Why does the engine revs drop too low and sometimes stalling when I engage any gear?


This can be either an engine management issue (bad idle air control) or a transmission issue if an automatic trans (torque converter lock up problem). Idle air control can often be cleaned so = cheap fix. Trans problem not so easy.

Engine starts and idles fine, but will not rev up (2001 Jeep Grand Cherokee 3.1 diesel auto)


If it was a fuel shortage the engine would rev but to limited speed. This is a lack of air to throttle body. Check for clogged air filter and all the piping and the throttle body.

Sounds like your IAC(idle air control) motor needs to be replaced. its on the bottom side of the throttle body. there are 3 phillips head screws holding it on.

When you say it's destroying the air filter---do you mean it's all sooted up ?? I am assuming that what you mean.
Try disconnecting the vacuum line at the egr valve and see if that helps.
But it sounds more like a plugged up exhaust system.Try disconnecting or looosing the flange before the cataylic convertor and then see how it runs.

My 2001 ford tauras sounds like its gonna stall when you first start it and the engine like comes on and goes off.


the idle air control valve maybe sticking and causing the car to want to stall until you start moving. it keeps the idle when not moving. it is on the throttle body where the air tube meets the intake. it looks like a 3" silver cylinder. common to fill with carbon after awhile, have the fuel injection cleaned at a shop after to remove the carbon build inside the intake. best of luck

the idle air control valve is responsible for engine idle.
this is a common failure on ford's. but I don't think yours is bad because it does idle high befor it dies.
you stated you had codes p0171 and p0174 these are lean codes for bank one and two, you said you found a vacuum leak and repaired it, the vacuum leak was mostly likely the cause of the lean codes, however the pcm has calibrated the fueling stategy for this lean mixture, what you need to do is erase the KAM "keep alive memory" this is done by unhooking the negative battery cable for 60 seconds, this is the only way to erase the KAM the $6000.00 machine I use wont even do it.

once the KAM is clean the computer will go into a relearn state and all operating values will be adjusted for the vehicles current condition, during this relearn session the vehicle may have some driveability issues (low or high idle, stalling, poor fuel economy) the relearn should complete within 10 minutes of idling and then 10 minutes of driving.

good luck and keep me updated
