Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

I HAVE A 2004 AZTEK AND HAVE VIBRATION WHEN PRESSING GAS PEDAL. WHAT CAUSES THIS?


you don't say where the noise is. that is important to give a clue where the issue is. when stopping on the brakes 3 things happen. you press the pedal and the abs pump starts pumping fluid. the second is the brake capilers start pushing on the rotors to slow the car. the rotors are attached to the wheels and that stops the car. so if the rotors are warped you will feel a vibration in the steering wheel when stepping on the brakes. if its your foot feeling the pump working that is normal for abs pumping. you should feel it and holding the pedal will keep it working and stop you from skidding if everything is working correctly

3.0L 2000 DODGE CARAVAN SHUTS DOWN WHEN STOPPING AT A LIGHT OR STOP SIGN. NO LIGHTS ON DASH - NO ENGINE LIGHT. TURN KEY OFF AND RESTARTS OK. MUST KEEP FOOT ON GAS PEDAL AND BRAKE PEDAL TO KEEP ENGINE...


it sounds like it is starving for fuel, the fuel filter may be clogging up. when a fuel filter gets dirty and cuts some of the flow of fuel, it will stall out at stops. because the engine does not have the proper amount of fuel to keep it running. have a good day !

I just bought a 1988 Chevy Suburban. I drove it home on Friday with no issue. I then drove it all day today while starting it and stopping it with no issue. I then parked it for a few hours. It now won't...


I would try to get a fuel filter first and replace that if that isnt it you probably have a issue with the fuel pump. also try taking a hammer and bang lightly around were fuel pump is located in the gas tank.If you have a issue with fuel pump and dont no how to drop tank and replace it you would be wise to shop around because it could save you hundreds of dollars.

Engine light on and engine keeps stopping


Happened to me...check engine light came on and had to keep my foot on gas rest of way home/while reversing into driveway. Try cleaning/replacing the Mass Air Flow Sensor...cost is between $115-$150 with out install (about $10 to clean if you do it yourself). Shellybear

Have you checked the charge on the battery? How bout your connections at the terminals. Vw are very sensitve to voltage drops. You might even have something thats draining your battery

sounds like the exhaust has restrictions. maybe the convertor is restricted or in the muffler.
