Hi there. A bit off help needed. I have recently had to change my old engine for a good used unit. Car is a Seicento 1.1 SPi Sporting 98 - S reg
Runs ok except for idle speed runs at a constant 1500 rpm once warm. I've checked for obvouis air leaks and sensor connection but seem ok.
You can hear the stepper motor correct if you blip the engine i.e. The revs die down then stepper corrects.
I used the coils and crank sensor of the new engine but everything else was of the old engine. I did find the small emmision pipe blocked up with self tapper?? and wondered if this was to correct old engine running problem. Maybe the ECU needs time to re-learn base settings? What kind of mileage do they need to self-learn ?
The engine light is not on by the way and it drives superb.
Any ideas thoughts useful...Thanks
