to elborate on the title.

from cold my gti6 starts fine, idles fine, runs fine.
when it warms up it runs fine, and idles fine for about 10-15 seconds.
the idle then become a bit misfirey and slowly gets worse and worse.
if i blip the throttle it cures it again for another 10-15 seconds.
if i dont blip the throttle it eventually feels like its about to stall/die.

sometimes if im trying to accelerate off from a standstill it also feels like its about to die/stall unless i take it out of gear and blip the throttle. again only when the engines warm.

im hoping its just my icv being dicky and it needs a clean/replace.

but just incase any other places/sensors to look at?

thanks in advance
jim

thanks for the reply

unknown.....cars been sat for 10 years, somewhat of a barn find.

i cleaned out the icv and oil bretaher lines other day, didnt seem to help.

i havnt been able to "test" or give it an "italian tune up" untill i had the cam belt done (today)

i have swapped over the exhaust from my parts pile....but i reused its exsisting o2 sensor.....it didnt look bad but thats hardly an indication.

by any chance are either of those two sensors "tested" if by unplugging either, it cures the problem?

also.. im not sure if the bogging down and irratic idle problems temporarily cured by me blipping the throttle or me allowing the throttle pedal to fully release and the revs drop past a certain point before i try and use it again. could this be a throttle position sensor problem?

Can you run a diagnostic? I'm betting on a failed MAP sensor.

Black T'99 Gti - may she rest in peace - written off in a shunt on the A329m

been tinkering today. found it it was missing a litre of gearbox oil :S (filled now)

i tried two spare map sensors i had in my parts bin. neither fixed the problems.

went for a drive with the lambda unplugged. both problems are gone.

ive also realised my check engine light, doesnt come on when the lambda is plugged or unplugged. (should it?)
the bulbs ok as it lights on 2nd click ignition.

hopefully when the new lambda gets here it'll fix the problems.

definately f-ing with me.

On Friday the problem appeared about 2 minutes into my commute to work (before she was fully warm).....solved itself about 5 minutes towards the end of my commute. (commute is 20-30 minutes)

was about the same story on the way home.....problem only occured mid journey and was fine at the beggining and end.

swapped the O2 sensor today (sat) along with a brand new map sensor, (and a new gearbox mount)
ecu reset. first drive, problem seems to of gone....but a new one has appeared... :S

i get a quite noticable dip in power past 3500 rpm, feels like ive let off the throttle or someone attached a heavy weight to the back of the car.

any ideas?

Im still and dingle and it didnt help.

just taken off the throtle body to fit new TPS, made no difference

new spark plugs
new coils packs (2nd hand)
new exhaust
cleaned ICV
new o2 senor
new map sensor
new TPS

if it turns out to be the green coolant sensor ill be annoyed with myself
