misterp Posted July 23, 2005 Report Share Posted July 23, 2005 Quick question for experienced PCM guys - I got some bad gas yesterday, fortunately only 3/8-tank. I refilled today at another station, the truck runs smoothly now but is down on throttle response, so am I right suspecting that the PCM needs time/mileage to reset fuel trims and advance? If so, how long or how many miles until the PCM 'optimizes' its tune? I need to know because I want to run 1/8-mile tomorrow! Thanks in advance - Mr. P.
