Hi, I have a 1994 Buick Park Avenue with a 3800 engine in it. A few weeks ago it started acting funny, It will idle real high when you put the car in Park like at almost 3,000 RPM's and when driving it as it does that it seems as if wants to take off like your pressing the gas pedal. It also will not let the diagnostic tool communicate with the vehicel. So I changed the ECM (the Brain) on the car it still will not communicate and it still Idle's high Please help me! My next step is to change the idle air control valve, and the throttle position sensor and also the mass air flow sensor, air temp sensor, and the coolant temp sensor. Oh yeah the vacc hoses to. I hope I dont have to get all of the parts I have listed on here. In dyer need of help!
have the same problem?
