Bad Cold Starting Problems - Help!
My 19 1.4 RT has become very bad at cold starts. I have done a service and replaced the distibutor cap/rotor and the HT leads since it started but it seems to be getting worse. Last night I checked the gap on the new spark plugs and set them to 0.8mm as per the haynes manual I have and it was just as bad this morning.
Once I manage to get it running, (which takes about 45 seconds or so of turning it over) it will splutter into life and will then run a bit doggy until it's warm. Also until it is warm it will hesitate through the revs from about 2000-3000. What I mean is when it's cold and ticking over if you put your foot down it will get up to 2000 or so, stall for a half a second and drop back a little before the revs pick up again- is this a timing issue? Other work recently done has been a cambelt 3000 miles ago (garage) and has run fine after - and the mid exhaust section.
I have read on some posts that cold start problems could be a coolant sensor / crank angle sensor problem??? Also a friend advised me to check all my servo hoses and the lambda sensor.
Any help would be most appreciated on this one!!
