So I still have this problem, but it is even worse now. If the engine is warm or hot, it will stall in neutral every time. Even when cold, after it drops down from high idle it will run low and rough. Sometimes stalling.
In drive or reverse its still perfect, cold or hot. One shifted to neutral, it dies like I turned the key off.
I replaced the IAC and it made no difference. Voltage at IAC read 11.5, S/B about 10.5 from what I read, but would that cause it? Tested the TPS and it checks out good .9v at idle and 4.5 at full throttle. Im lost, I cant even check codes anymore since it wont stay running.
