Supra Reving by it self

Recommended Posts

Hey guys,

my mates supra has a problem that on idle it just revs by it self, he has changed the throttle position sensor (TPS) and that has helped alittle bit but its still reving,

 

what could b the issue?

it needs to rev to stay on..

 

more info is needed, but look at things that control the idle, like the idle control and the throttle body

sounds like a vacuum leak. does it do it when its cold, or warm, or only one.

Its a non turbo 1993 model supra, The car is completely stock he has not changed anything at all, besides the TPS which sort of helped fix the problem but not entirely.

 

This problem occurs when its cold as well as when its warm, it doesnt matter.

My fj20 did a similar thing it would just rev up but to like 7k and was a massive leak as the manifold bolts were loose as f**k. So maybe check to make sure everything's tight.
