Have you done a diagnostic from the vehicle since?Are you having a check engine light coming on?If so you may also need a reset of the system.

IAC - idle air control valve . What are the fuel trims at ? Are they with in + or - 10% short term an long fuel trims ? Do you know what fuel trims are ? What's the IAC counts at looking at scan tool data ? Or are you just guessing to find a fix ?

Fuel injector


Check the idle circuit- idle motor or idle air control. The computer controls idle, but the motor or controls may need attention.. Also the throttle body may need cleaning of dirt and gum deposits, varnish, etc. Use an intake cleaner spray can.

High idle problem


HIGH IDLE COULD BE ACCELERATOR CABLE BINDING PULLING THE ACCELERATOR PEDAL OR YOU HAVE VACUUM LEAK AT THROTTLE BODY GASKET.WHERE GASKET COULD CRACK SPLIT APART THROTTLE MOUNTING BOLTS LOOSE OR YOU COULD HAVE FAULTY IDLE AIR CONTROL VALVE.IN WHICH IT WILL CAUSE CHECK ENGINE LIGHT TO FLASH.

What sensor is controlled by the accelerator pedal? What sensor controls spark timing? Both on a 1997 v6 Rodeo.


Hello Wayne.
When you depress your accelerator pedal it increases the voltage output of the throttle position sensor mounted on the end of the throttle shaft.
No one sensor adjusts timing though. The inputs from several sensors are integrated inside the ECU computer. Then the ECU adjusts the timing accordingly.
Base timing is taken from the crankshaft position sensor and the camshaft position sensor.
Engine temperature, engine load, revs per minute, gear ratio, speed all have the most effect, but there are others that will have slight effect as well.
If you have any more questions leave them in "add comments" and I will return your question.

My xj6 runs at high rpms and accelerates on its own


None of those possible problems have anything to do with idle speed. The first thing might be a very weak throttle return spring. The next would be a sticky throttle cable or foot feed pedal that isn't moving freely. Another possibility is a vacuum leak somewhere. Did changing the spark plug in #1 cylinder help the misfire? If not, you may have a partially plugged injector. Fixing the misfire will only increase idle speed some more. Look for an idle speed motor near the throttle body that is supposed to raise idle speed when the engine is cold and lower it back when the engine warms up. Check to see if it is holding the speed too high. If the throttle position sensor tells the computer where the idle speed motor is set, then it could have an effect on idle speed if the sensor is bad. The position sensor is just a fancy potentiometer. Hope some of this helps.

Problem while driving 1987 jeep cherokee


Your engine is stumbling "off idle" - as it switches from idle to throttle control. The idle air motor regulates the air flow and engine speed at idle. If the idle is smooth but the stumble occurs just as the throttle is pressed this isn't the problem, The MAP sensor is mounted in the middle of the firewall behind the engine just below the hood. It has to sense the manifold vacuum drop when the throttle is opened. This my first suspect. Second would be the fuel pressure regulator. If it runs O.K. after you get it going, this is a weak suspect unless it loses power when pulling. A bad fuel pump, again low fuel pressure. Just like the squirt from the accelerator pump in the carburetor days, the injectors have to deliver a good stiff shot of fuel when the throttle opens to keep the engine from stumbling. The MAP sensor will tell the ECM a squirt is needed but the fuel system has to have the pressure to deliver.

RODEO 99 ECM PROBLEM


that can happen for several reasons the least being the ecm. first thing is it could be a weak fuel pumpand the only way to check this is with a fuel pressure gauge. it should be between 17 and 25 psi. next it could be the TPS(throttle position sensor) this controls your idle. this is located on the throttle body has a weatherproof plug and is held with (2) screws . next is the engine speed sensor this helps the ecm adjust the fuel/air mixture in conjunction with the TPS,IAC valve,O2 sensor<and the egr valve. to pinpoint the sensor problem you have to have a diagnostic scan done. please rate this.......thanks
