won't rev over 1000 need help asap
my 05 gt has been sitting for about a year. I hook up the battery it starts perfectly. go to rev engine and nothing.. Will kinda sputter up to 1000 but no more. pulled codes and came back throttle stuck or closed. it is not throttle body works fine opens and closes like normal but Rmps do not go up. I have an over sized borla, exhaust, NOS, after market air system and a tuner. was given the car so not sure of the tuner or anything like that. also fail safe mode is on. a brake.line is cut so could this be the issue for.some reason? I want to get the engine.running before I work on brakes or anything else. please any advice will be helpful. have been told maybe tps. how could I test the tps. thanks

The brake line is unrelated. Check the wiring under the hood, especially the MAF wiring. Rodents are known to get under the hood and gnaw wiring. I'd also try another tune but I really doubt that's the issue. It could be a number of things. A year of improper storage could cause a host of things or it could be a non-storage related failure. Could be fuel, bad sensor such as the TPS...

If you have Traction Control System, push the button to turn it off. For some reason, it could think the car has lost traction and is limiting power to the engine. I think you probably have a chitload of problems, not just one.

I don't think it a chit Loa of problems. idels beautifuland this car only has 4000 miles on it. it was a show car. I've checked all the wiring seems okay. what's got me baffled is when I put the connector back on to the throttle while pressure is on the gas it'll kick in and sound normal for just. few seconds. and my traction control is off and won't go back on. what's up with that

Well, it sounds like you may need to start a list of problems. The TCS should default to "on" when you start the car and you should be able to turn it on and off at will with the pushbutton. If that's not happening, put that on the list. But if TCS is off and NOT coming on AND you still have the hesitation issue, then... add that to the list.

The brake line might be the cause of the issue. If the abs system registers no pressure it may cut power so car cant continue increasing its speed.
Not sure if these sensors are in place or even installed in these cars but it is a possibility.

Had a similar problem with my Traverse... would freak out like it was possessed. Would not allow HWy speeds and the traction control system was F'd up. And the only thing I did before this went nuts was swap out a spare tire for the flat.
Turns out it was a speed sensor on the transmission that was throwing the TCS system into a frenzy.
Dealer replaced it under warranty.
