I have a problem with a 92 buick century 6 cyl that either runs at a fast idle or stalls when it is idling. The check engine light does not come on.
Sometimes it runs fine, but not very often.
Any ideas?
Thanks Joe
What engine?
V6 3.3l
That engine is not known for manifold problems. Several things to check: vacuum leaks from hoses, etc. worn out TPS dirty MAF Remove the console trans switch - indicator light assembly and resolder EVERY solder joint.
