My blazer used to have a high reving noise when i started to drive and from different topics on here i figured out that it was the iac valve so i replaced it. Now the rev thing stopped but now when i go to stop or when im idaling, my truck dies. it starts with my rpm and my oil pressure fluckuating quit a bit and then it just cuts off. any suggestions on a cheap quick fix?

 

might check your brake booster. just a thought.

 

I guess im what you would call car illiterate. When it comes to wires and electronics and stuff i can do that, but engines throw me through a loop. Pics or a brief description as to what your talking about would be much appreciated.

 

try checking the throttle positioning sensor or the ignition control module and coil.
