Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Good to hear. I thought there may be something that we could not see blocking the cruise. Thats the way it goes with auto repair some days. As for the turbo, that does seem odd. Does the vehicle seem like it is surging when this does this? The only thing that comes to mind as a possible cause is an incorrect reading from the manifold pressure sensor which the engine controller uses to judge how much boost to give. Monitor the pressure reading to see if it is fluctuating incorrectly. Also monitor the vacuum solenoid that controls the turbo dump valve for cutting out and go from there.
Good job on the cruise. I am glad to have helped.
Hey, Jim. I still have not received any word on this one. To be safe and, if you feel comfortable with it, start another question about the turbo concern and then put something in the question to request me if you would like. I will try and grab it as soon as I can see it.
Talk to you later
