I have a 2004 Monte Carlo with the 3.4 V6. If you read any of my previous posts I have been having trouble with my RPMs revving up and down while driving a constant speed. I still have no solutions for this problem. I read somewhere how this guy had the same problem and cleaned his throttle body a and MAF sensor and had success. I am wanting to try this but I am having trouble finding a video that shows me how to properly do this. If anyone can help that would be great!
