HELP! Car only idles after TPS calibration
Stupid car. I swear, I always take one step forward and eight back.
Found that the negative battery cable had a bad fray on it leading to an occasional no start condition. I fixed that with a ring terminal, and the car never ran better after doing that.
I have been working on getting my basic tune set for a while, so I haven't removed the overboost limit yet. I upped it from 152 to 179 and burned to ECU. Then I recalibrated my TPS. Oddly, the last time I tried to do this, I couldn't get it read 100% at full throttle. This time, it read the full sweep like a champ. I chalked it up to my bad ground.
But when I went to pull the car back into my driveway, it stalled. For whatever reason, I can't rev the car out of idle. I can slowly SLOWLY give it gas (not changing the MAP reading) and it will rev all the way to redline, but giving it any kind of gas at all leads to it stalling out. My wideband shows full lean when it does this.
I don't know what I'm doing and I'm ready to kick a small animal through a brick wall.
Any assistance on what to check would be great.
