So far its showing P0430 & P1273, but from the research I have found and actually my cats, that probably is popping up due to the cats being cleared out previously. Guess no platinum for me, lol! Regardless I bought the ECM Relay and placed clamps on 2 vacuum lines yesterday, and so far no stall nor shut-off. The Engine seems mechanically sound other than those codes before. I was worried it was the TCM but from what I have read there would be a UCOMM code showing with my scanner. So today's drive from work will be the true test while in traffic to see if it was only the ECM relay that was bad. Wish me luck, and still need to buy some interior plastic trims and re-upholster the driver side seat.
Okay, well the verdict is in!! Conditions drastically improved after ECM relay was installed but i loss power and eventually it turned off on the way home today. Left it off briefly while still rolling in neautral in traffic and started up again just fine. Kept going home, when i arrived home it started again losing power and sputtering but staying its lowest around 500 rpms more or less. Im suspecting either vacuum leak or MAF because i disconnected it and the engine changed to a stronger stance. I connected a scanner and still same codes, despite the ones for disconnecting the MAF temporarily. The scanners live readings showed O2 sensor (2) displaying low reads during times of failure. O2 sensor (1) was at a constand. I turned off the car and on with the scanner and then it read as both o2 sensors reading around the same.
*Remember my cats are cleared but it shouldnt be reporting "lean" codes. Hence why i suspect its breathing in extra air somewhere
