Yes, this is about idle problems, but it's past the basics now...
Well I've reached the end of my line on stopping the galant from dying at idle when it reaches temp.
I have no vac/boost leaks that I can see or hear. (using soapy water ect)
I rebuilt the TB.
3in exhaust no cat magnaflow muffler
Boost gauge, running boost off wastegate pressure (10lbs)
I've essentially replaced everything on the intake side, from the Jpipe up to the intake Mani gasket.
ISC/TPS are In spec, no cels
The car runs fine at cool temps, I assume the ISC is doing its job correctly. When the car reaches temp, or aprox 8 miles worth of driving, the idle will begin to falter when I push in the clutch, say to put it in N for a stoplight.
If I I turn the car off, say to go into a store, when I come out she runs fine, till the temp is back up and the same issue repeats itself. Here are some videos to depict what's happening.
I'm I'm need of obscure help, because the basic vac leak/FIAV/ISC answers aren't going to cut it anymore.
First video here is showing the fresh cool motor idle, with a few second of exhaust.
Second video is me at a stoplight/sign with my lame issue, I blip the gas up to 1500 for a second, and the end I'm trying to hold it around 8-9
Third video is me coasting down a side street in neutral, showing the same. The. A small third gear pull
I swear this has to be something temperature related. Maybe computer related? Could it be the ECU? I don't have another one to swap out and see.
She was playing nice when I took the videos and didn't die at all, just faltered. Usually she will bounce down once or twice then die on the third try. It's quite embarrassing really.]
