Mileage = 170000 Engine size = 3800 V6 dash lights = check engine work done prior = none for awhile work done to repair = none tech = SF question = check engine light has been on a few weeks now. About a week ago the car has taken to dieing when the engine warms up.. You can go about 20 miles just fine then she starts to die especially on right hand turns.
SF: Anytime a check engine light is on, the first step is to get the codes read from the computer so as to have some direction for diagnosis. Many things can cause a check engine light, and many things can cause the problem you are having. You could be having a sensor problem, a wiring problem, a fuel pressure problem. Getting the codes is the first step.
