It Revs up to 1200 rpms and then falls back to idle and when you let up on the throttle you can get it right back up to 1100 or 1200 rpms but as soon as you try to rev it past that it falls right back to an idle. It starts great and has been a great running little pick up but this has me stumped everything else is running great? Anyone have a suggestion Tom Greenleaf Ultimate Carjunky / Moderator Jan 7, 2012, 7:53 PM Post #2 of 4 (1711 views) Re: Engine Problem/Electrical Sign In John - Welcome to the site and right now IDK what to suggest but will try something. This was a tricky year however this was mechanically a bit ahead IMO. It may have an RPM limiter that is confused. A wild azz guess is if a TPS fixed identical problem before then perhaps wiring to it is the trouble? Does anything change if you leave it unplugged? Just to clarify - are you saying you are pushing the throttle/gas pedal and engine just harmlessly returns to idle as if ignoring the request? Can you rev it from underhood with a long screwdriver and make it go higher?

Do you know if you can put the sensor in wrong? Thank you for your help.

You could try just watching the ohms smoothly change or take it out again if easy enough and make sure it is on/installed such that it get turned with the actual position of the throttle. The rod that turns throttle plates may have somehow broken and isn't really turning too so take a look that it really opens just by and with the engine off looking down/into throttle body, T   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
