View Full Version : 92 gts revs up to 5k only

08-25-2016, 07:53 PM
Stock 5sfe. Bone stock, already ran a fuel injector cleaner through it but no dice. No cel is on, was on before but it was the water neck temp sensor. Already checked timing and its spot on. Maybe fuel issue? Previous owner said they changed out the fuel pump and i have thw receipt to show for it. Maybe regulator?

Already swapped out plugs and wires and no luck either.

Any other ideas guys?

Check the TPS on the throttle body.

Stupid question, but did they do the filter when they did the pump?

Yes the filter was changed.

Murgatory. How would i check it? Resistance with a ohm meter?

My '93 ST had a similar problem. Different engine, but it was because I bought a cheap distributor with a shit igniter. Your igniter is separate from the dizzy, but does it sputter at 5K, or just stop revving, or backfire?

I would also check the fuel pressure and ignition timing.
