That’s why i ask about the sencers what they do. I work on cars last 15 years. Older ones. I put my baby (92 fulsize Blazer in the lake in fefruary. Dads idea go ice fishing. That was bad day. Took the two weeks to get it out and 30k later. Morow of that story is DO NOT GO ON ICE.
Anyway got a 98 grand prix with 3100 changing head gaskets and intake gaskets well redoing the top of the engine. All the sencers i had to unhook. Made me think why and how? Before is a gessing game what sencers and throw bunch of money at it. I took ericthecarguys advice from his videos and youtoob and learn how to chec stuff. with the ohm meter found out that my aic is no good.
I love older cars they are simple. The newer one just more and more electronic and one sencer could make car run like crap. Then stressing if car will pass or fail emission test. It’s nice to know now how to check and fix that. So i’m pressy happy.
