I tried to run my cossie up today, just to warm it through as its laid up at the moment but it is missing really badly. It starts ok but you have to use the throttle to keep it running and it smells very rich and fumey, any ideas ??????

 

sensor at back of head??

 

Any moisture in the dizzy cap?

 

plugs if I had to guess - but check:

* if dump valve, remove vacumn hose and plug it while running and see if it improves
* spray carb cleaner around hose connections/intercooler to see if the engine revs up
* remove Idle Control valve, clean with towel and reinsert
* pull out spark plug and check how sooty it is - change if necessary

 

Sounds like its knackered!

Tell you what, I'll take it off your hands for free!???

 

Map Sensor gone down?
Or dirty/broken crank sensor?

 

maybe its just saying " i want to be driven more often not locked up in this smelly garage" lol

 

broken dumpvalve will only cause faults on small turbo not latge turbo (dunno wot one yours is)

misfire would cause rich smell if its a bad miss...

 

try plugs mate!

 

I am having the same problem as well, I think it could well be the blue coolant sensor at the back of the head causing the engine to overfuel when cold and foul the plugs.

 

Its a 3 door Jim!

 

I,ve found it. It was a bared wire coming out of the MAP sensor plug rubbing on the earth strap It,s nearly ruined my Christmas and Nearly caused a divorce ( It kept popping out to garage to try different things and the mrs was getting a bit ) Thanks to all those who made suggestions ,Gaz

 

glad its sorted dude

 

At least it was a cheap fix.....

 

Like a handjob, it's was a cheap fix Bet thoughts of selling the car crossed ur mind!!

 

I dont know about selling it , setting fire to it crossed my mind though !

 

Swap ya
