hi! Would like some help regarding check engine light on 98 Blazer with only 100000kms .Runs perferct.

 

Could be a variety of things .If you have an autozone around they will scan it for free and tell you what is tripping the (dummy light).If not look around for a local shop in your area that may do it free or cheap .MY .02 is that it is probably O2 sensor if you havent changed it recently pricey little buggers hope this helps...

 

Yeah, you need to get it scanned and get the fault code. once you get that, then tell us what the code is. otherwise, no one is going to be able to help you. if it is an 02 sensor you need to know which bank its on and if its upstream or downstream. theres 4 02 sensors. so get the code and maybe we can go from there.

 

thanx for your help marriedguyinlove240 and 2tone ,snowman.
