So, I drive to Walmart the other day and everything was fine. I start my car afterwards and I hear a valve tick. It was time for an oil change so I thought that may be why the ticking was there. I pull out of the parking spot, and as I press the gas, it stuttered so bad, the car was almost bucking…
I start limping it home and after 2 minutes of that, it ran decently. It still was not at full power, maybe 80% power, but the bucking and huge hesitation was gone.
I run the codes and got a bunch. See pictures.
After reading some forums, I see that one of the codes could be caused by bad diodes from the alternator. I replaced the alternator and cleaned the codes. Car still did the same thing. Idled great, but as soon as I go to drive it, it hesitates and bucks. I
changed the Cam Positioning Sensor on Bank 1 (passenger side), still same thing. I changed my oil, MAF Sensor, Fuel Filter. Still same thing… idles great… as soon as I go into first gear and give it gas, it grumbles, hesitates, and bucks.
Please help….
