Simply put, the car intermittently stalls while on the road, and there isn't much to go by as I haven't really identified the stall conditions. Even more weird, unplugging the MAP sensor brings the car back, and it runs fine in reduced RPM limp mode.
I don't get any codes when it stalls, and I have a Micropod 2, as well as the Witech software. When I did check the PCM, I couldn't get it to talk (Funny enough, this is while the engine was running too). So I had just replaced the PCM, but still no fix. I've replaced the MAP sensor, and Intake Air sensor. I've replaced the coil packs, and re-gapped the sparkplugs. I have new injectors, and the intake manifold is clean. I've checked the harnesses, and they're all good, the fuel pump is ~2 years old (I had it fail on me). I had taken the plenum out, and scrubbed it down to get oil residue out, and I had removed the throttle body to clean it with Throttle body cleaner and some cotton pads.
Additional info, I was in a front end accident in 2019, and had redone the body work, control arms (upper and lower), struts, and tie rods.
I also had some initial issues in December where the car would misfire, but not throw a code, which caused me to clean, and rebuild the intake, as well as coils, and injectors. After that point, that is when my car would intermittently stall.
I'm kind of at a loss here for where to go now. The issue is clearly electronic, because when it runs, it runs great. But when it does run, there is some hesitation with the throttle response. The thought did cross my mind that I could have a CANbus issue, but I've ruled it out since I'd see more modules acting up, and throwing weird codes.
If anyone has the pinouts with what the expected resistances are for the throttle body, I'd love to see if maybe I messed up my throttle body. Some spec data would also go pretty far, since I can read all the data coming from the car.
Thank you very much for reading, if any info is needed, I will gladly supply.
Also sorry if this sounds a little scatter brained, I'm trying to remember all the things I've touched, while also thinking about what I could have messed up. I've been to a few shops having them check my work, and nobody has identified any issues, heck nobody has even been able to get it to stall. Also the car shifts fine, and I had the trans checked, which came out clean.
