[QUOTE="DOWNS, post: 438456, member: 21038"] Sounds like your TPS may have a dead spot. Unless the TPS is completely kaput, it may not throw a code for it. Get your multimeter and back probe the center wire on the TPS connector. Switch the Jeep on (don't start). You should see 200 millivolts at idle and 4.8 at WOT and as you slowly turn the throttle valve from idle to WOT you should see a smooth increase in voltage without any sudden drops. I'm willing to bet you may find a dead spot just off idle or a bit more. [/QUOTE]
