Asked by menge Jul 16, 2011 at 04:30 PM about the 1992 Toyota Pickup 2 Dr SR5 4WD Extended Cab SB

Question type: Maintenance & Repair

3.0 V6 Has a rough idle and bucks/studders under load and acceleration.  I have replaced the fuel pump, spark plugs, cold start injector, EFI Temp sensor, Distributer, CAP & Rotor and no luck.  It will start fine when cold, but has a hard start when warm.  It back fires, bucks and has no power (more studdering) during acceleration. Any thoughts out there?

There is a recall to replace the head gaskets on that specific 3L V6. Google it for the number but I think it is 3V2 recall number due to poor gasket manufacturer. I had my 92 done and it works great now. L Lee Biloxi MS
