Get hold of your engine supplier and ask for the ECU (computer) and the whole wiring from the same Jeep ASAP.

Ask them can you stop by an compare the connectors and pin-out

There are few different between Federal and California emission.

California emission engine + ECU will have more sensors.

Make the call ASAP and take careful note on the pin-out from the org. Jeep.

I have a 1990 4runner with 214,000 on the motor. I have recently replaced the plugs, wires, cap, and rotar. When the truck is cold and not warmed up yet it stalls out on me. I start it and it idles high in...


probably the IAC, not usually the TPS, have you replaced the fuel filter? it could be a problem with the new wires, yes they may be new, but there is always a chance it is faulty, kind of sounds like a misfire. It could also be the spark plugs. or possibly you have them plugged the number 1 wire into the wrong spot on the distributor

1998 Jeep Grand Cherokee 4WD 5.2L V8, Multi-Point Fuel Injection System. Idle is low, stalls when you let off the gas, sometimes smells of gas. Could this be IAC Valve or TPS Sensor or maybe fuel...


I would suspect the iac stepper motor may be dirty or plugged off when coming back to idle. I would try cleaning it and the throttle body at the same time. Q- tips make it easier to clean and brake kleen makes It easier to remove the dirt. Were safety glasses and gloves with the aresol brake clean. After everything is clean you can reconnect battery and you will have to test drive for the iac to relearn it's steps. Hope this helps

How do you fix the idle on a 1990 isuzu trooper 4 cylinder, and where is the adjustment?


The idle screw is on the throttle body near where the gas pedal cable attaches to it. Not sure what sensors it has and less familiar with pre 90's cars but if it has an IAC or TPS could be causing problems. Clean the throttle body/carb.

I have a 1999 that will not start or even fire


The engine cranks but will not fire? If checking for spark finds sparp at the plug wire at the plug. add fuel to the air intke to see if it'll fire some on the added fuel. if theres no spark then the crank senser may have failed and the test is to unplug the throttol postion senser and measure the voltage with the key on. then unplug the cank senser ( at the back of the intake manifold ) and if the voltage at the TPS changes then the cranksenser is bad change it and you'll be good to good.

1990 f150 w/5.8 FI motor, idles good, take on road, it boggs down


Have you changed the tps? The tps is like a dimmer switch with the idle being the lowest setting and everything above that being progressively stronger. If the switch is bad it will not advance spark or gas flow.
