I am getting a very strange hesitation at 5000-5500rpms at HALF THROTTLE to 3/4 throttle. It does NOT appear to be present at WOT.



It seems to be running a little lean maybe? like loosing fuel. I'm not quite sure but it's all of a sudden, just kind of studders (than i back off the throttle and all seems normal), i just noticed it tonight as i was coming home on the usuall twisty roads in 3rd gear.

Any idea's on what the stumble/hesitation could be?

Rebuild time.



Try adding some more ground wires on the engine, and cleaning up the current ones. Could also be the tps, try re-setting that.

 

Ok, i'm an idiot. A couple days ago i did the TB mod, removed BAC and EGR. and well. (dont laugh) forgot to plug the TPS back in! lol. strange that it ran fine all up until yesterday, than started acting up.
