run fault codes to find which sensor is not correct

scan the computer with a computer scanner just to see what it says. check your intake, I am thinking your mass air flow sensor is no good. it happened to my car where the rpm increases and decreases when the car is idle. Or it can be the IAC valve.

When was last tune up??? Plugs, wires, all filters & fluids? Especially fuel filter. I'd start there and run a good fuel system cleaner through it.

Check for codes
May have a bad Coil

think you need a engine mountin and some tranmition oil in the matic tank in the boot thanks ben

buy a bottle or two of gas line anti freeze, it absorbs any water that may be in your fuel. add one bottle now and one the next time you fill up. if it is water as i suspect you will notice results almost immediately.

It does sound like a vacuum leak. Get a can of WD-40 and start spraying around the carb. It will rev up, and U can pin point the loose vacuum hose, are crack vacuum hose.

idoling positioning sensor is going out just happened to minn

check fuel filter then check the ignition system
