Injector advise on the R please.

[foammanmark]

Something I know very little about so please don't take the mick. My R has whites, and ever since the Rica map was fitted, it has missed quite noticeably at 3-3,500rpm. I've run injector cleaner through her, V-Power all the time but she still misses. Should I try blues or greens, or just have my whites cleaned properly please? The map was not 'made for my car', but for someone else's.

[merc85]

Why do you think its a injector issue??

[foammanmark]

Why do you think its a injector issue??

Partly because of the lean running issue that I had, which seemed to be mainly down to the vac pipe being disconnected though. The injectors may well be nothing to do with my issue, but I have to eliminate things as it's annoying me.

[merc85]

Can you not try another ecu to rule that out?

If I had one, then yes. My ecu was swapped for the mapped one. So I need to try a fwd manual R ecu, if anyone can help please?

There is a good ECU compatibility table here - http://turbo-tuner.co.uk/ttusb-compatible.htm

The website wasn't available a few weeks ago, so I'd recommend copying it asap if you need it ;)

EDIT - Oops - just realised yours is a V70, so its a motronic 4.4, in which case that link isn't applicable sorry. I'll leave the link just in case any 850 owners need to refer to it

[jamesy12345]

To check if the ECU is OK, I think you will need one from a similar car to yours, Mark. There are lists of ECU numbers (http://forums.t5d5.org/topic/7489-ecu-codes/)on the net but just take a look at yours

My ECU number is 0 261 204 449 as below but is an auto so not much use to you

How old are the.plugs in it? Might be getting blow out on them and need the gaps closing a little try this first as it's free:) close them to about 22 thou

[M-R-P]

Shrek's R coughed and missed at about 3500rpm under "heavy load", we changed leads, dizzy, coil and plugs (and fitted refurbed blues) and not only did the cough go away but it went like a mo-fo too :)

This could well be the answer Mark, I'm getting an occasional mifire at full throttle full boost, so will regap the plugs first.

When mine was being mapped felt like it was blowing all 5 out BIG stuttering lol

[960kg]

Recommended gap is 0.8 which is 31 thou`ish .......mine are set at 0.7 which is 27 thou........i would say 22 thou is too low as 25 was the norm. before metric and electronic ignition!

Miss firing at 3-3,500rpm on a turbo is usually plugs but get the proper Volvo ones not Bosch or NGK ......Volvo specified Bosch ones will give no problems even after a large mileage whereas any of the other makes may give miss fires at around 8,000mls and you won`t find the problem as you think you have new plugs!

Pay once, fit once, fit Volvo!

The map was fitted at the same time as a full service end of July last year, so I presume the plugs were changed at the time. I'm sure that the gaps will be spot on too, but may be worth a look.

I have a service coming up, and will ensure that decent plugs are fitted. In fact I will take them for a spin in the car and let them feel the splutter for themselves.

the point they are making Mark, is that your service people will have set the correct gap for your car, but your re-map may require a closer gap set to counter the extra boost trying to blow out the spark a certain points in the rev range.

Q: Do I need to set the "gap" when installing a new set of plugs?

A: Maybe. A spark plug part number might fit hundreds of different engines from many different manufacturers. Although the NGK factory will set the gap to a pre-selected setting, this may not be the right gap for your particular engine. The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy, and accelerated plug wear. It is always best to check the gap against the manufacturer's specifications. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. The gap should be adjusted by only moving the ground electrode.

Another consideration that should be taken into account is the extent of any modifications that you may have made to the engine. As an example, when you raise compression or add forced induction (a turbo system, nitrous or supercharger kit) you must reduce the gap (about .004" for every 50 hp you add). However, when you add a high power ignition system (such as those offered by MSD, Crane, Nology) you can open the gap from .002-.005".

You Shouldnt re-gap platium/fine tip plugs, there will be another Part number with the correct Gap.

Right, the car is in for a full service at Readview Volvo on the 22nd of this month. Therefore, new plugs and we'll see if those with a reduced gap to normal makes a difference. Let you all know after I've tested her.

The only plugs not suitable for re gapping are the three pronged ones, stated in the appropriate Volvo Handbook



VOLVO is Bosch

Read my post again it says Volvo Bosch........which are Volvo specified plugs made by Bosch......Bosch cannot sell them as it is copyright!.........The only proper specified plug for the STANDARD engine is Volvo Plugs

I dont need to read your post again! THERE NOT COPYRIGHT!! they have the right to distribute FACT!

[oblark]

Volvo don`t make spares. They get company`s to make spares to Volvo spec and label the parts "volvo"

[960kg]

I dont need to read your post again! THERE NOT COPYRIGHT!! they have the right to distribute FACT!

Volvo spec. plugs are copyright as they have spent years with there manufacturer,Bosch to get the heat range correct for all models, Ford plugs after 2005........ and also want to profit from them doing so.

Here are a few posts from the VOC of which Clan has worked for Volvo`s for over 40yrs.........there are loads of different items made by others to Volvo specs for Volvo and they are not off the shelf at the aftermarket places they are all captured parts from Volvo.

One of my friends works in the parts department at Volvo and he says the same about plugs.....you cannot buy a Bosch plug with the Bosch part number on it from Volvo ......ONLY the Volvo specified plug made by Bosch with the Volvo code pressed in around the centre metal part of the plug.

To prove to yourself go try and buy a set with a Bosch part number as i have asked my mate and they cannot be ordered.

[merc85]

Bosch like other manufactuer's spent ££££s Designing there plug for VOLVO Bosch are the Owner of the copyright NOT volvo!

Your saying Bosch spent £££s develping a plug then made spent £££s making a lesser plug to sell to the aftermarket.

Why dont other manufacter a VOLVO badge?? well its because VOLVO own the Name so other's cannot copy that why you cant copy a Volvo or any other vehicle embluem.

We will have to agree to disagree, Eurocarparts/Unipart/Central auto supply and thousands of other motor factors are now going to go out of business because of supplying all these copyright infregmnt lesser parts.

Oh btw ive just bought a Bosch air flow metre, Oh just noticed that every part number on the air flow metre is the same as every other part number on the original Bosch volvo air flow metre, funny that?

One more point keith, I havent pushed my Company on this thread mate. nor the sale of plugs to anyone on this thread.

[soothingduck]

Its getting pointy in here :duck:

[merc85]

Its getting pointy in here :duck:

Bosch make that particular plug for various other vehicles too, NOT just for Volvos hence you dont see the Volvo number on the plug (ONLY THE ONES from Volvo). It would certainly upset the local ford comunity. lol

[soothingduck]

I worked at a motorfactors untill 2012 and would say bosch make a range of plugs to suit all cars with the bosch name on them BUT they do not make all plugs with bosch on them. Each bosch plug will match a number of makers part numbers because the plug is close to each makers plug requirements. If you want the plug for your car that is set right then you need to go to Volvo otherwise said plug may need to be adjusted. Yes bosch made the volvo plug but they made it to Volvo spec ie the gap/temp/lifespan. A plug with the Bosch name on it will be close but not quiet spot on.

There i've said it now.

[soothingduck]

Its not a copyright thing its just good business. I think the Bosch range goes to number 57 or so and that covers all engines. If they made a plug just right for each car they would need a range of hundreds.

[Jamest5r]

Anyone want a beer :)

[merc85]

I respect your opion but the gap is the same as the volvo plug, its thesame plug. you should not re gap a long life fine tip plug. btw the plug range is massive as you quite rightly said it would need tobe, :)

Yes, if you have 70bhp more then go up in the heat range with Bosch but not on a Standard motor, even an "R" which are just simply "rip of price" standard.

The reason i don`t admit i am wrong about plugs is because i am NOT wrong and whenever i give advice to help others is because i can back it up with facts about my advice.

But seeing as you are talking aftermarket, yes i agree i know nothing as my Volvo is a reliable 100% Volvo as i only buy Volvo parts and when i sell it soon it will be a very good buy for someone. It does not have parts on it that need to be replaced after 6 or 12 months due to inferiority......There are an awful lot of genuine Volvo parts that are cheaper and more reliable than copy parts, most think they get a bargain from aftermarket parts.

No way would i travel at such speeds my V70 is capable of with aftermarket parts installed....
