So I'm at a breaking point with my 2001 Chevy blazer and don't know what to do in the last two years I've had it I replaced the crankshaft sensor maf sensor o2sensors spider injector new catalytic converter new distributor cap and rotor spark plug and wires and starter and ten different codes still come up ! As I was driving on the highway the other day it just randomly loss power and any time I go to step on the gas it takes a while to get it going someone suggested it could be the iac valve or it could be something else just trying to find someone who may have experienced this issues or know the best way to go kind of in a tight budget and really don't want to get rid of my truck so anything will help thanKs!
