Hello all just wondered if anyone can help.. i have a couple of problems with my cossie any help on the matter would be great.

First off the car is running a stage 1 conversion just chip acctuator and exhaust only changes.

When car is started from cold if you let it sit there and idle for a few minutes its not to bad but if you try and move the car just a slight increase in the revs it then starts to miss not major but if you dont keep the revs up it will cut out also it does seem to rev its self quite high when this happens. once your on the move it seems ok.

Driving around at low speed the car seems to be quite jerky seems to be a problem around 1000 - 2500 revs mark if you hold the revs say around 1500 the car seems to miss and seems a bit jumpy but when driving around at normal speed with the revs at 3000 + it seems fine.

Sometimes when the car is idleing it will idle nice and smooth (very rare) but nearly all the time it will idle and it seems to drop a bit then back to normal and keep doing this but not a continuious straight idle.

Ive checked the dizzy (phase sensor). and its got ngk plugs i changed these a few weeks ago but no change in the prob. also cleaned the parts on the throttle housing (idle screw) etc.

Any help would be great

Thanks

 

hello matey have you tried changing the coil?

 

My escos has the same problem , i have changed plugs , MAP , coil , injectors , lambda-sensor , fuel pump and filter , amplifier and loads of other parts . I would appreciate if somebody knew whats wrong

 

Guys, our 2wd was misbehaving (stuttering) on partial throttle, turned out to be the throttle position sensor that was not working 100%.

Just a thought and BTT for you guys.

 

is it only when cold? have you cleaned the idle valve, they arbour loads of shite in them, i had mine untrasonically cleaned and you would not belice the amount of gum and grime that came out, another one to check it coroded connectors.. anythwre on the loom
