SOURCE: Rough idling/loping at idle it otherwise runs fine

1. Vacuum leakage Check throttle body and intake manifold for tightness. check all vacuum hoses.
2. Faulty fuel or pump or electrical.
3. Plugged PVC valve.
4. Air filter clogged
5. Leaking head gasket.
6. Camshaft lobs worn.
All of these porblems can cause lopes or erratic idle.

SOURCE: ROugh idle

there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
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.

SOURCE: check engine light is on: engine idles rough

IT SOUNDS LIKE THE IAC (IDLE AIR CONTROL) MOTOR IS BAD OR GOING BAD, BUT THE QUICK SOLUTION IS GO TO ANY AUTO ZONE,OR ADVANCE AUTO PARTS STORE, AND THEY WILL CHECK IT FOR FREE,& TELL YOU WHAT SIGNAL CODE MADE THE CHECK ENGINE LIGHT COME ON, I WOULD DO THAT JUST TO BE FOR SURE, BECAUSE THERE ARE A FEW OTHER THINGS THAT CAN CAUSE IT AS WELL,SUCH AS MAF SENSOR DIRTY,OXY SENSOR GETTING A BAD READING,ETC.

SOURCE: 2000RS 2.35/4G64 sluggish,rough idle,poor MPG,check

Sounds like an O2 sensor, go to An autoparts store like Schuck's, Autozone, or O'Reilys, and they will be able to a free scan for you, and tell you what your check engine light is on for. Or if it isn't on they could still tell you if it's a bad O2 sensor by reading the live data levels. Good Luck! :)

What causes a rough idle on a 2003 Nissan Sentra Spec-V? Car otherwise runs fine while driving.


The rough idle is associated with the p011 code. The P011 code is: Camshaft A over advanced. There is a mechanical fault with the intake camshaft.
You need to take the car into a mechanic, preferably the dealer since they have all of the needed special tools, to properly diagnose and repair the issue.

My 2003 GMC Sierra idles rough and cut off sometimes when turning.Replaced fuel filter and changed plugs.engine light stays on.Which 02 sensors do i need to replace first? Before converter or after...


Before replacing the O2 sensors, I would check the fuel pressure. You may also try to have someone pull a trouble code from the powertrain control module to verify why the engine light is on. Do not replace any parts until this is done, otherwise your going to be guessing at the root cause, and it will get expensive with part replacement.

2002 Impala idles very rough


it could be as easy as replacing plugs and wires..but first check every single small diameter vacuum line you have as these get old the crack and get brittle i had a rough idle once and found a cracked vacuum line leading to my MAP sensor. i just cut off the worn end and just shoved it back on and it fixed it. Also its not very likely, but you do mention something about fuel gauge... so if you"ve never replace your fuel filter i'd spend the tim if to replace that as well. if its the new style with plastic clips, you just take a pair of pliers and squeeze and pull to release..but release pressure on gas cap before trying to replace the filter. can i get a very helpful thanks.

90 chevy cuts off and idles up and down


Sounds like their is to much air getting to the engine. This is caused by an air leak in the vacume lines. Try replacing all the vacume lines on the engine.

If you have the vortec motor they are notorious for the fuel pressure regulator failing. Have the fuel pressure tested at the fuel rail. If it is below or at 56 the engine will have hesitation or rough odle and no power.

Please contact me if your problem presists.

Thanks, Charlie
