well as i was driving today, the car did not respond upon me pressing on the throttle. it only happend for a fraction of a second. but its the first time. it only happened once today. and the rest of the day was fine. i look under the hood but everything is stock. i havnt tinkered with it yet. just bone stock.

 

Hate to say it but probably a TPS problem. I've had it in the past. Engine idles fine but flooring the pedal had NO effect at all. A sticking TPS plunger will do that. How to fix? Maybe some electronic switch cleaner from Radio Shack or??????

 

it happenes more on startup but its fine after the engine is warmed up. i guess i will just go and lube it up then thanks.

 

can someone tell me where the tps is?

 

Its a black push button with wire connector thats located on the front of the throttle body, its pushes in when throttle is closed and comes out when throttle is opened.

 

its not stuck but its fine after like 7-10 mins

 

It looks different on an S5. Since you didnt specify which engine you have its hard to say. In both cases though it faces the front of the enigne off of the throttle body. The S5 version has a wedge that looks like a throttle arm that runs against a switch and a push button switch like the S4's.

its not stuck. the no throttle responce just happens on start up. and it goes away after 7-10 mins

 

Im not certain on this, so dont take it as gospel, but instead somewhere to start your search.

IIRC there are a second set of throttle plates on the secondary runners that are designed to stay closed when the engine is cold and they open once the engine warms up. This is to prevent you from beating on a cold engine. that may be your problem.

Someone else verify or add to this?
