Default Error Code P0303/Check Engine Light

Hey, all -

I love my car. I have a 2007 PT Cruiser that has 100,000 miles on it and has been a great source of transportation from the time that I got it.

Recently, I started having problems with my Cruiser. At times, the engine would be really difficult to start (turn it over, have it start, go up to about 1200 rpms and immediately die - even if I pressed the accelerator, it would die after the initial rev up...this usually persisted until the car wouldn't turn over any further and then, after a few moments, it would start).

I took the vehicle in for service at a mechanic - they replaced plugs, wires and some type of oxygen sensor that (they say) causes the engine to "flare" correctly when starting. They also insisted on doing a "conditioning treatment" on the engine to remove carbon. According to their scan, the only code that came up had to do with a "new key" -- nothing more. Since this point, I have had some problems with starting the car and the engine light coming on and intermittently flashing at points.

Any ideas? I've been told in the past that engine fuel injector cleaners can cause the check engine light to come up at times. I pulled the error code last night - P0303 - but when I checked it later, it came up with nothing.

Thanks for the great forum!!

OK, so you took it to a mechanic, they charged you for all that was done and now it's doing the same thing. Take it back and tell them you want your money back as everything they did didn't help.
