I replaced my dead engine with one from a yard.


The car does not want to idle. When I give it gas, the rps drop. If I hold the pedal down, rpms slowly climb.

Once the rpms are above 2500 I can hold them and it revs smoothly.

Since then I have changed the TPS, TPS wiring, MAF, Idle control, plugs, plug wires, Fuel pump, battery, battery terminals, alternator, ecu.

Seems like a tps problem. What should I look to replace next?

Injectors
Crank/cam sensors
Throttle body

Please help

I'd take a careful look at the hoses for the Idle Air Bypass and other vacuum hoses in that area, and inspect them for leaks/clogs.
