Ok here’s where I’m at.do the test, i said it was good, why are you even thinking maf or tps?
STAY THE COURSE! ONE THING at ONE TIME!
report what you find.
and stop!! with the excuses
I went outside and tried to crank it. It made crunching/clicking sounds almost like a dead battery but not quite, and wouldn’t crank. I adjusted the battery cable terminal and was eventually able to get it to start. (I have video of the noise it made).
I tried disconnecting the IAC. CEL came on, but the car would idle and did the same thing it’s been doing (dying after a few minutes).
I tried disconnecting the MAF. Same exact thing.
I tried disconnecting the TPS. Same exact thing.
I tried disconnecting the other sensor that’s in the cold air intake tube between the MAF and the TB. Same exact thing.
When I first reconnected the unknown sensor and started it with everything in place, it cranked for about 4-5 seconds before it would fire.
Observing the idle closely, it seems to sputter for just one rotation before it dies. It doesn’t struggle at a low idle, it just drops extremely quickly and dies. But prior to that, it idles at a normal RPM.
I also tried a few more times to start it and let it run with everything intact. A couple times it would fire and then IMMEDIATELY die.
My theory is that the IAC is physically stuck or clogged, and needs to be replaced or cleaned.
