I really need help I got a car 4 weeks ago I brought a car (03 Chevy Malibu base 142k mil, 3.1L V6) and the check engine light was on, so it was no way for me to pass state inspection. I replaced the battery, did a oil change and a coolant flush. Went over to autozone and had them scan it for me and code p0306 was coming up, so I changed the spark plugs in the front cylinders (2, 4, 6) and the wires. So I went to a shop to have them inspected it and put a sticker on it. But it failed, so the shop started working on it to get the code to clear, first they changed the coil pack thin the injection valve, nothing worked thin they checked the locker arms in the motor and seen that one of them was broken and lost the thread. They replaced it thin seen it messed up a piston and they replaced that. They started it back up and the p0306 code was gone and now they say its giving a p0300 code. They have had my car for 7 days now. Can anyone help me out on what to tell them to check next time I go. This is my first car.
have the same problem?
