Replace the spark plug wires, it will most likely cure the problem.

With Auto Temp---you first need to use professional
scanner, to look at Body Module Data & continue from
there,it helps to have factory trouble charts to use &
not guess, as I'm afraid some shops still do

After replacing tps developed small miss at high speed over 40 mph tried another one same problem


I don't think I would replace a tps for the small miss at high speed, although it may have seemed plausible at the time.

I only replace the tps when it shows degradation on the scanner.

Does your computer detect the miss on any given cylinder? If so, that's where I would look next.

Have you tune up your car lately with spark plugs, wires, air filter, fuel filter?

I recently bought a 1992 model toyota camry SV21 and 3S-FE engine, it starts well exept that when you try to accelerate, the engine will miss and would like to stall, so just to bring it home I rev it high...


the fuel must be adjusted ,it loses the torque, when press the accelerator ,the engine need more torque when moving the car on 1st gear,compare on the motorway,check for the fuel man ,this will affect the engine on long period

Are you sure it isn't the fuel pump or filter just running the cleaner through might not have been enough. Also the fuel injector might be something worth looking at.
