[QUOTE="infrared, post: 1431447, member: 68615"] Jerry, I'd be the first to say, I'm no expert on your issue. I would say, go for the easy stuff first. Since the ECU handles all of that fuel stuff, I would try a good contact cleaner on the plug (and repeated re-connections of the plug, with cleaner). Cleaning or replacing the TPS might be the remedy, but no digital readout of TPS operation is going to show [I]glitches[/I] there, only the seriously bad defects. Some multimeters have a bar-graph readout across the screen, besides the number readings, which can show "stutter." Borrow a better multimeter, if you do not have that option on your multimeter. The bar graph [U]will[/U] show "stuttering" performance of the gadget being tested. Since you have a 2006, an ECU re-flash by Ivan's Performance (Georgia) is probably worthwhile, even if that does not cure the problem outright. Like I said, though, I'm no expert there. [/QUOTE]
