850 r olive holding revs on changing gear

[matt_t5r]

hi long time no 850.. 96.. just drove to launceston 280 miles and purchased an R on a whim.. i missed the bruised banana..

anyway.. could you point me in the right direction (its been 2 years),,
when i change gear the revs hold for a second or so. also idels at 11-1200rpm. the banana had a similar problem but was an auto. cant remember how i fixed it. im a little lost plz help

Idle control valve

I know where your old car is, cat d had a black bonnet for a while

[Ettienne]

Take it off clean it out with spray cleaner or such like and make sure you can hear the ball bearing rattle.

[matt_t5r]

lovelly will try that first..
i loved my old car.. is she alive again.. the guy that bought it spent some £s fixing but ended up selling her as she developed a knocking?:-(
still best looking t5s by far

[Ettienne]

No he sold it on then it changed hands again, had a manual conversion now iirc

[T5frankie]

They all do this it's the map

[matt_t5r]

the map? how do u mean. as in ecu needs remap?

[matt_t5r]

tried cleaning icv but still the same :-(

[claymore]

I just unplug the icv, I run all my 850's with them disconnected.

[matt_t5r]

does not make a difference if i disconnect it. actually idles slightly faster too.

[stribo]

Have you tried adjusting the throttle cable, it maybe too tight.;)

[MoleT-5R]

Possible air leak in that case ??? or may be the throttle body needs a good clean, as it could be crudded up and not shutting fully, those would be my next suspects.

[oblark]

Air leak. simples

I had the same problem when I changed my engine, it was the seal between the master and the servo.

[matt_t5r]

cheers for insight.. know what im upto sunday

[T5frankie]

the map? how do u mean. as in ecu needs remap?

i had two maps for my 850r one held the revs and one dropped instantly when foot released, to be honest that made driving the car horrible very jerky on/off/on, its made/mapped for a smoother drive, if revs increase then an air leak is the cause i reckon

[ajc106]

had this on mine it was the vac hose on the end on the inlet manifold by the thermostat right pain to get to but just get a length of vac pipe and run it round to the vac tree on the turbo intake pipe

[matt_t5r]

just realised im only firing on 4 cylinders. the leads look old so they will be replaced. im hoping that will sort out that issue. wont know till tuesday wots wrong. im hoping its not to painfull. im anticipating a huge bill :-(

[matt_t5r]

off for repairs today. now i gotta dtive a 98 ztech focus to work :-(
after its running right i have been looking for shocks.as front i.bit soggy. complete coilover kit £250 pro 3000.??? anyone used them before?

[stribo]

I've got a set on my C70, they improve the handling a lot, but ruin the ride.

[Wobbly Dave]

We have a group buy still going for BC Coilovers - which should be better quality/ride.

But well over twice the price. ;)

[matt_t5r]

ok...
nsf hub done
oil n filter done
plugs leads n cap done... firing on 5 again.. phew..

issue still remains wih holding revs.. is it likely that although i hear rattle in icv it could very well be causing my problem and still be knackered..

when disconnected it drops revs when changing gear....

[matt_t5r]

ok.
. throttle body cleaned but not removed..
. icv cleaned
.2 x vac hose rubber elbows renewed.

still holds revs changing gear.

.am i right in thinking that icv althogh free could still be up the creek.. when disconnected it drops revs.
starts idleing at 900 from cold increasing to approx 11-1200. this is same with icv disconnected..

[T5frankie]

see post 6

[stribo]

See post #11.

[matt_t5r]

#11.... ok. cable seems to be free. gunk free on throttle spring... dose not appear to be snagging or too tight..

#6..... assuming it points to the map what would the solution? i never bothered to research tuning beyond its factory setting,
bought car recently so mot really sure if its been tuned/mapped previously.

[matt_t5r]

finaly sorted rev problem and sure enough it was all down to vacume..after changing all apparant hoses and pipes with no joy i found refuge with a guy from near dover who sorted problem.. i now know where the hose under the radiator is
thnx all

[stribo]

Glad you got it sorted.

[Saaamon]

It should idle at 800 and it should hold revs between gears.
