Hi all,
I've been having engine problems with my Colt for about a year but it's got to the point where I'm totally out of ideas. I've been trying all sorts of fixes suggested by members of many forums but nothing seems to help.
Here's the spec:-
Mitsubishi Colt UK 1.3i (4g13 engine)
102,000 miles on the clock Manual transmission 1994Here's the problem:-
Car fires up straight away whether hot or cold but when cold will die straight away, fire and die, fire and die (you get the picture) Seems to take forever to find a steady idle but when warm seems to be quite happy. Main problem of this is that for the first 3-5 minutes of any journey it will almost certainly stall when pulling up to junctions, lights etc (dangerous to say the least due to breaks and steering being power assisted) It strikes me as being a mixture issue with the emissions smelling very rich, also, when it's cold it requires constant throttle to keep it going, even though i have the fast idle giving it some more revs.
Things i've already tried:-
New plugs New Leads New distributor (needed this as the car broke down and wouldn't go at all without a new one) New coolant sensor New fuel filter Drained fuel tank Cleaned all electric connections Tested O2 sensor and gives a reading once warm which appears to be within parameters Cleaned induction air filter Checked stepper motor
As you can see i've tried all the high profile checks but still the same problem with poor to non existent idling from cold. I've also tried all combinations of biss and fast idle screw but no joy.
Any ideas would be much appreciated, sorry for the long post but that's pretty much all i know, any other questions please ask.
Thanks all
David
