Looks like a classic idle air control IAC problem. The ECU should normally enrich (prolong the injection cycle) if load is put on the engine such as engaging drive or putting input to the power steering. It can only do this if it knows that the throttle is fully closed according to signals from the throttle position sensor on the throttle shaft end (see the outside of the throttle body at opposite end to the rotary accelerator linkage). The ECU then allows air passed the closed throttle plate> This is doen by two possible ways 1) a motor in the TPS eases the throttle plate open just a fraction or 2) a port on the side wall in front of the throttle plate is connected via an opened IAC valve to an exit port. If it is the valve type, just ensure that everything is clean by using carb. choke spray or WD40 and cloth/brush to remove oily carbon build up. Ensure the valve can open and close freely. If the TPS motor type ensure that everything is very clean and that any micro switch associated with sending 'throttle closed' signal to the ECU is also clean and able to click freely. AS a final measure check all the vacuum lines to the inlet manifold for any leaks, ingress of un-metered air needs to be ruled out as another potential problem source.

2004 jeep liberty won't move when put in gear (like brakes are locked).crank it in neutral put in gear it will go till i touch brakes then won't move again.WHAT'S WRONG WITH THIS THING.


gear, is this a Manual trans? or AUTO you said gear.
what gear, please name the gear, 1,2,3,4,5 R
or PRNDL ( a/t box auto matic) what shift lever selection?
what is out door air temp, you do know brakes can get wet and freeze right?
it wont go you meant? until brakes are touched, key word won't?

ok engine only starts in PRNDL set to N??
is that it?
and then when you shift to D, the car will not move
what about the other gears.? try them all yet?

my guess (wild) is that you dont know how park lock out works.?
that you must hold the brake pedal down to shift to park or neutral.
is that it? (read operators guide?)

my guess is car is not drive-able. key point1 (a dead car)
point 2, engine starts and runs. and races on demand with gas foot.
point 3, im lost. (no trans stated or clear symptoms.)

my jeep has 6speed manual box
and the clutch allows me to start car.
on Automatics trans must be in park or neutral to crank engine.

"it will go till i touch brakes"



I read that 10 times,
my 2nd guess. the engine stalls ?

IS THAT IT, stalls means engine RPM is 0
and right foot actions are dead.
and all dash lamps glow, telling you STALL is now.

9-3 Saab stalls while driving on freeway without warning and after drifting to side put in park starts right back up and drives


The problem may be a dirty throttle body. Clean the throttle body with a recommended cleaner and you might want to add some injector cleaner to your gas tank. You may also want to check your vacuum hoses and make sure they are in good repair. I hope this helps. Good luck.

95 cherokee sport stalling


Since the car stall only in the drive position, it sounds(i'm not there to actually ck the car)like when the engine torques, it might be pulling on a harness somewhere and killing the ignition. Do this,start the car and under the hood while the engine is running, move or jiggle the harnesses around and see if the car stalls. If the car stalls try to pinpoint the location on the harness and look for frayed or broken wires.

I put the car in gear and drive 30 to 50 yards and then it stalls. the car starts and idles good. i can rev it up to 3000 rpm's whith out it stalling but as soon as i try to driv it it stalls.


There is an electrical connection located on the transmission. Disconnect the connector and try to drive it again. This will help to determine if the problem is located in the transmission or engine related.
Let me know.

2002 sequioa sudden stall


Often when the battery is disconnected or replaced the computer will lose it's learned idle settings. You could try letting the engine idle in park until the engine temperature comes up to normal and leave it like that for a few minutes, then put the Air con on and let it idle again for a few minutes, then switch the air con off and put it into drive. If it does not stall, let it idle in drive for 2 minutes or so, and then do the same with the Air con on. This should relearn the base idle settings and stop it from stalling on you. Before you carry out this procedure you should make sure that when you replaced the battery you didn't remove any other plugs or knocked anything that may be causing the fault. If you try this procedure and it still stall when you select drive, you will need to get a Mechanic to check the vehicle over.

Hope this helps,
Mark.
