1995 1.6xel engine. This is the ecotec 16valve.
Having idle problems.
Looked at most items airvalve throttle etc.
after some other feedback and reading on the net net item to look at is the MAP(Manifold Absolute Pressure) sensor.
This can be chjecked by looking at the ouput voltage at differned revs.
Unfortunately I can find no information of what the voltage should be at different revs. The hays manual just says the vaoltage increases at higher revs.
Any one looked at this and have good information on what a perfect MAP sensor should ouput at idle 750revs, 1500revs, 3500, revs
Also any one know what sort of price these are, and if expensive where to get a good second hand one!!
