Suburban idling irraticly

My suburban has been acting up since we changed the plugs, it seems to idle irraticly when in park and when slowed down at say a intersection or a light, we had also changed the wires, distributor cap and rotor, and the pcv valve.

Check the wheels and see if the drums are not tight. and also the erratic Idling Could be from your Torque converter Clutch Solenoid that doesn't work properly and if the Solenoid gets totally bad then your car will be stalling.all Well i can say is Check your transmission fluid level and your brakes. Good luck

Try replacing a valve called the Idle Air Control Valve, if your car has one. See if that solves it. Not sure where it is located on your specific vehicle.

Idle irratic


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue 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
