I am at a loss with this car.... it started idling high at start up, changed the TPS ran fine for a week, started having trouble starting, then it started stalling going down the road, then it started backfiring through the throttle body. It starts up after multiple tries and idles rough when I put it in gear it starts to backfire and will not move.
