replace throttle body gasket. first check to see if carbon has built up around the throttle valves in throttle body if so remove and clean it with throttle body cleaner.and a old tooth brush. besure to remove all electrical components or any thing that plastic or rubber the cleaner will destroy it.

SOURCE: battery light stays on

Your alternator isn't putting 14 volts out to the battery. Check the stator wire on the alternator and the 3 wire plug make sure there is no gap on any of the alternator connectors and they are on VERY firm!

Hook up a multimeter inside your car and watch the battery voltage! if under 14volt you got an alternator problem!

Sounds like your heated 02 sensor's heating element is not working. Is the check engine light on, when it starts and is running bad? Have the engine codes read to see if the 02 sensor is defective.

If you are referring to the Check Engine light then this indicates there is a problem with the emissions system. Have the ECU scanned with an OBD2 scan tool. The fault code that has been set by the ECU will tell you where to look for the problem. If the engine is running fine there is no hurry, but do have this looked into. If you are referring to the oil pressure light stop driving the car until you get this repaired as it may be serious.

Why is the 'check engine' light come on? The top of the radiator on my 1993 3.0lt Toyota Camry V6, 3VZ FE engine split some months back and it overheated. I replaced the radiator but realized after that...


First you need to have someone hook up some sort of code reader to the car's computer to see why the light is on. Take note of the code or codes stored in the car's computer. I would clear the codes from the computer's memory and see if they come back, indicating there is still a problem, and go from there.

92 mitsubishi libero, engine surges downward in cold air, when accelerator pushed engine suffocates. difficult starting cold.check engine light on when warm, runs fine in warm weather or city driving


DIFFICULT STARTING CAR IN COLD.WOULD BE A THERMO - TIME SWITCH.THE THERMO TIME SWITCH CONTROLS THE AMOUNT OF TIME THE COLD START VALVE IS HELD OPEN BY MEASURING THE COOLANT TEMPERATURE AND UTILIZING A TIME FUNCTION TO PREVENT AN OVER RICH CONDITION.THIS COULD BE MOST OF YOUR PROBLEM.BUT SCAN IT TO SEE WHAT PCM CODE YOU ARE GETTING.
