This happened last week for the first time and I replaced the battery and cleaned terminals. Moved main TPS a little up from where it was turned all the way counter clockwise to about where it was marked by previous owner. Car had been running great for the past week. Rpm's at 650-750 at idle with transmission on Drive.
Car is currently with hood open and positive battery cable off. I'm thinking the battery had nothing to do with and the RCU reset is what got it back running normal again. Dunno. Also, noticed noticed A/C compressor would not come on. Turned the A/C on while driving it home because I assumed that would raise the RPM and keep it from turning off at stop lights. I can't stop thinking this is throttle position sensor related. This car used to jerk every time I would try and pass 2,000 rpm when I just bought it and I replaced one TPS sensor which I later figured it the trac TPS sensor and not the main sensor and this got the car running great for months, the A/C would also shut off but the A/C button would flash in this instance. Thanks in advance for reading this far, I know being an internet mechanic has it's limitations and this grasshoppa is nowhere near being a masta.
Any comment appreciated even if it's a long shot.
have the same problem?
