Question about 1995 Chevrolet C1500
Hi, I'm really puzzled, about four years ago my truck started to idle @ 1100 rpms. (not the normal 750) So, I ran to the autoparts store to buy and replace the iac valve which apparently solved the problem. About six months after a got the same issue and another iac valve, after few months another one. then,the problem came back later. this time I just cleaned the valve and the truck ran just fine. The problem continued but I learned by accident that disconnecting the battery something was ''reset'' bringing the engine to normal operation.
The good thing is that I don't buy valves any more but I have to have my wrench ready behind the seat to disconnect the battery when needed.
I ran the scanner to get the stored codes, it happened to be the coolant sensor. it was replaced but the idle deal continues.
my truck is 1995 chevy 1500 vortec v6
any ideas or suggestions would be greatly appreciated.
Is your air cleaner good ? Replace aircleaner. look for leaks of anyliquids or debris that may be keeping the valve dirty.
