Hello Scotty! I found you on YouTube, anyway, I hope you can help me. I drive a '03 Turbo Chrysler PT Cruiser, 2.4L it has over 102,000 miles. We have had to have the car turned into a salvaged title, because my wife had a small accident and our insurance co said it was a total loss. The reason I'm laying this foundation is because I don't want to invest too much more money into this car BUT want to keep in running for a 2nd backup car to get around locally for a few more years until my wife retires.

Soooo, last week the check engine light came on and with my OBD scanner and the codes were P0031 Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 and P0037 O2 Sensor 1/2 Heater Circuit Low which were showing the 02 sensors were bad. So I replaced the Upstream & Downstream sensors. I cleared the codes and they stayed off for about a day. So, I was driving it the other day and the car would act like it wanted to stop but then it would go and act like it was being choked and it hesitates etc. Now, I've been driving for over 50 years and have had a few cars stop running when the catalytic converter clogged up and go bad. So, after watching a few videos on YouTube and NOT wanting to put too much more money into this PT (Which, by the way has been a FANTASTIC car!) I removed my Catalytic converter (Which, I figured was most likely clogged up) from the car placed it in my shop vise and proceeded to gut the inside of the CC. I used a mask and sealed up the honeycomb and the felt and ceramic that came out. I ordered a 45 Degree Oxygen Sensor Spacer to move oxygen sensors away from direct contact with exhaust flow and to do away with the check engine and the codes from coming back. Well, this evening when I drove it to a friends funeral, the car would still hesitate and stalled out but then it would be ok and really get up and GO! Seems like it got worse when it got hotter. Any suggestions? Could it be Faulty Engine Control Module (ECM) which is the same as the PCM. If it was this, seems like it would just go bad and not work, NOT be intermittent when it works. By the way, spark plugs, wires and the ignition coil are brand new. We use 91 octane in the tank

Thanks, Eddy
