1991 missing at Idle
91 C4 Missing At idle l
Hello,
I'm trying to find out why my car misses at idle, it's a 1991 C4 auto with 112000 miles the car runnes strong when you step on it, but when you come to a light it will miss a bit every once in a while not steady, it doesn't break down when you get into it hard, it just seems to do it at idle. When it cold and you first start it up it starts right away and runs good untell it warms up. I've can't find any vacumn leaks and there are no codes except for code #12 the plugs are new and the wires are to. and it has had a BG service flush on the fuel and cooling systems. can anybody help it seems to be getting worse.
thanks Larry
