Question about Jeep Cars & Trucks

1 Answer

Yes, my 2004 Jeep GC Laradeo, 4.0 Liter, was idling too high, began misfiring, would overheat easily if not moving, poor mileage. We have the idle air control valve replaced and throttle cleaned.

Helps with the idling, problem. But now it has POOR acceleration, the RPMS jump and fall without any acceleration. Now notice a slight shake of the car. Took it to Auto Zone the meter gave a code of P1763. What could this be?

The overheat problem is the thermostat

Posted on Apr 19, 2015

Testimonial: "The overheating seems to have stopped with the idle under control. It's idling good, but have this RPM jumping and with no acceleration, if I try to pick the speed up with acceleration the RPM'S really jump.. Auto Zone ran their diagnostic thing on this trip and got the error code. I need some assistance, as this is my transportation to work."

How do I adjust idle on 2009 Toyota Corolla 1.8 liter


There are no provisions for adjusting the idle . The computer through the use of the IAC valve - idle air control controls the idle . There is a base idle set at the factory an should not be changed or messed with . What idle problem are you having ? low or high Could be IAC valve or air passages plugged . High idle the throttle plate could be gummed up an sticking ! If you were to change the base idle you cause check engine light problems .

Start by checking to make sure that the a/c condensor and radiator is not full off debris. If the condensor and radiator were full of debris it will limit the air flow from the engine cooling fan which in tern will cause a high discharge pressure on the discharge on the a/c causing poor or no cooling at idle and could also cause vehicle to overheat. Check and make sure that the cooling fan as well as the condensor fan are coming on together when the a/c is turned on if equipped with 2 fans.
