I have changed the TP sensor, map sensor and engine computer module with all new parts. It starts fine but won't stay running, unless I keep the tact around 3000. "Service Engine" light still on. Scanning it still addreses 1) baro out of range, 2) 5 volt output too low, 3) TPS voltage below acceptable minimum.
HELP, I'm LOST !!!!

Did you check sensor circuits? Is the 5-volt ref signal ok? Does your scanner show live engine data? The voltage on the tps signal, does the reading move up and down smoothly, when you work the pedal. What is the reading?
