Engine + Driveline / Re: Rough Start/Idle, Power loss under acceleration (Code 1223)

Replaced the blue temp sensor under the intake and all the wires seemed to be in good shape for their age. Still have to remove the cel to see if it solved my problem. Will most likely remove the intake manifold and replace the black sensor (the one inaccessible without intake removal) as well later this week. I've read that to clear the cel you can stomp test, wait for your code to flash, then hold the gas pedal down for 15 seconds to clear?

Engine + Driveline / Rough Start/Idle, Power loss under acceleration (Code 1223)

« on: October 20, 2020, 11:26:00 PM »

Hey I'm a newbie to this forum and looking for some help.

On my way to school today came to a stop at a stop sign and my car stalled randomly. Took me a few tries of turning off my car and on again for it to turn over, and when it did it had a super rough idle. I turned it off again, waited around 30 seconds then started it back up and my idle sat around 1200. When I press the gas pedal I would get power loss and my engine would almost die. I ended up parking it at school for a few hours and got it running after a few minutes before heading home. I stomp checked my engine light code at home and it threw the code 1223 for my coolant temp sensor but I was wondering if anyone would have any other ideas of what this could be? I've read online that the c191 connector on m20's was a big problem but can't find anything on it or like it for the m42.

Any help would be appreciated, thanks
