The car dies at stop and idles rough at low rpm


OBD Tools 365 Days Shop
A rough engine idle can come from a variety of causes. During the winter months, cars may have a harder time starting and will shake when first turned on. This form of rough idle can easily be mistaken for other problems. Engine idle problems can also be attributed to malfunctioning components, such as spark plugs. Holes in the air intake valve can also cause a rough engine idle because of excessive amounts of air being drawn in.
The rough idle of an engine can signify a power loss in the car. This loss of power could lead to other problems, such as excessive gas consumption. This lack of power can also lead to additional wear on other parts of the car. Ignoring problems with the engine of can lead to a massive breakdown that will require you either to make costly repairs or replace the car entirely.

Car starts running rough at idle, eventually quits running. Has new plugs, wires, cap, fuel pump, fuel filter, air filter, IAC Valve, and gas cap.


Back then, Honda suggested timing belt replacement every 60,000 miles. If your Honda has that much mileage or more and has never had the belt replaced, now may be the time.

1996 Jeep Grand Cherokee stalls when brakes are applied


My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.

Truck losing power and service engine soon light on


Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.
