When I first start the car in the morning the car runs real rough. When I start backing out, the engine hesitates and sputters like its going to stall. When I move forward and depress the gas pedal it does the same thing. At first going down the road it acts in the same manner. But all this only lasts for about 2-3 minutes then it runs normal the rest of the day. My mechanic does not know whats wrong with it either, and he is pretty good at what he does, but this one is a mystery to him as well.
Do you

Hi
Worked for Mitsu for many years and they have a problem with carbon build up on the intake valves. Causes A.M. Rough idle etc. Have the injectors cleaned this will clean valves also. And add a bottle of Techron by Chevron now and every 15 fill ups will keep all clean.
Thanks for Donate
