my boy has a rex with a LS in it for some reason the car revs to 7 grand and keeps going when you start it, all the vaccum lines are good and the fluids are filled, and the wire harness is new, but the ecu wont throw a code so i can fix it....does any one know how to fix this.

Also I am thinking about turboing out my LS/VTEC Rex, i have built all motor cars before but never turbo and i was wondering if anyone had good ideas or advise on where to start

 

is the intake manifold gasket good, or how about the throtlebody gasket.

 

i'd check tps wiring. maybe someone forgot to reverse the outer pins.

 

what is the wiring for the tps sensor....if you have an hf harness you shouldn't have to re-wire
