Problem: When I start the car in the morning (Floirda) it seems to run fine until it gets warmed up. Upon accceleration from a stop the car begins to stumble between 1800-2000rpm. It's as if the car feels like a few cyclinders are not firing or starving for fuel, however the car will drive it just won't accelerate. Sometimes by getting off the gas it will resolve it self once above 2000 rpm. However, most of the time I have to pull over and restart the car. Sometimes I can shift to neurtral and restart and it will clear up. But most of the time I have to restart the car.
Today: Took the car to Autozone to have the engine light read. the results are as follows
P0300, P1347, P1351, P0171, P0174. I had the tech clear the codes (engine light off).
Started the car drove fine until I stopped at a stop light. Upon acceleration the car started to stumble. The engine light came back on. Pulled car over restarted the engine light went out and the car drove fine until the next stop light. Upon acceleration the car started to stumble as usual and the engine light came back on! Took it to Autozone (read the codes) this time P1347 no other codes. Had the light turned off. Drove car home car started stumbling again the engine light cam back on.
Anybody have any ideas? There are no apparent vacuum leaks that I can detect. The last time this happened the dealer replaced the lower intake boot (vacuum leak) the next time the dealer changed out my Exhaust Position Sensor, seemed to work for a while but back at square one again. I do not want to go to the dealer again. HELP???
