So. my T5R failed its MOT. failed for De-cat pipe. BOTH licence plates are illegal. and emisions are way to high Co 0.492% n allowed like 0.100%. so i need a cat converter. 2 new plates and all with ££££ all money left over cause the money i spent servicing it and trying to fix the misfire DIDNT WORK! she still coughs on idle and on occasional pulls will just completely cut out. im seriously confused n need some help if anyone has any ideas?
If you put your car in for a MOT with no CAT no wonder it failed. As the car was manufactured with a CAT it sholud have a CAT for it`s MOT. You will find your emisions would be alot lower with a CAT, you find it sort out your running problem. As for the number plates :doh:
Is your decat a cut and weld or proper bolt out cat?
Also.that sounds like a.maf problem you.tried another in.it?

yeah the decat pipe is a bolted one. but i cant find another bolt style cat. unless anybody knows one before i buy this one with a entire downpipe?. and new plugs leads dizzy cap rotor arm but no coil as i ran outta money. i got a used one comming in the post from a buddy. it was working when removed from his car + the king lead. a few have sudgested the maf but im getting no codes for it comming up on my obd1 nor the o2 sensor as i thought it could be either of them. and i know it didnt have much hope with a decat. but it was worth a try. he did test it n said if it passed or was close enough we could make it work. but C0 for mine was 5 times above what your allowed. still the cough persists but it wont do it on pulls. general driving or if i just keep it slightly above idle with my foot
Idle control valve OK?
yeah thats still fine. still drops down rpm when changing gear. still idles perfect just the occasional splutter like its cut fuel or spark or something
so. would anyone have a bolt style cat i could buy off them or point me in the direction of one? cause otherwise i have a full downpipe+ cat on watch on ebay thats the correct volvo partnumber i need. just if we could slide that on n such itd help hugely. need it to pass MOT so i can get back to work n such the splutter i can sort after its road worthy again
[QUOTE=hemihusky;749386]yeah thats still fine. still drops down rpm when changing gear. still idles perfect just the occasional splutter like its cut fuel or spark or something[/QUOTE] that can happen when idle valve is closed/disconnected, I believe...maybe someone can correct me
i thought when they start to play up when you shift they liked to hold rpm? or is that a map issue? im just taking a wild stab ya know
[QUOTE=hemihusky;749392]i thought when they start to play up when you shift they liked to hold rpm? or is that a map issue? im just taking a wild stab ya know[/QUOTE] if they stick open rpm will raise/fail to drop. Me also just having a guess
:)
yeah see if i had a cat i could just put in where the decat pipe goes it would make life so much easier. but currently just gonna buy a whole new dp + cat n bolt it up to the BSR n call it done. cause i just want it to pass MOT atm so i can get to work again as atm im stranded on unpaid time. n not doing alot of good
You not look at my post?? will that fit??
i dont think so. mine has 2. 2 bolt oval flanges (like the one on the back end of it) and is completely flat. rather than having the angle up
[QUOTE=hemihusky;749417]i dont think so. mine has 2. 2 bolt oval flanges (like the one on the back end of it) and is completely flat. rather than having the angle up[/QUOTE] Sounds like yours is a custom job like I made. Symptoms were like that when my maf & idle control were goosed.
ill jus go through everything slowly I guess. may replace the O2 sensor when the new DP + CAT goes in as itll be easier outta the car. n then check the others
