Sounds like you may have a clogged catalytic converter. do you hear a air rushing sound from the exaust when accelerating? or alot of intake noise. have someone rev the car up and feel if the exhaust is superhot but be carefull!! you should be able to hold your hand there for a couple of secounds about 3 inches away without burning yourself. if it is superhot you have a bad converter. disconect the exhaust from the engine and sewe if the power is back to normal. good luck

Starts good wont idle stalls. if i give it a mid rpm will hold steady, let go of throttle runs rough and dies


Hi Russell:
I'd start by looking for a vacuum leak, often associated with the PVC valve. Make sure the PVC valve is not obstructed. Possible dirty air filter.
How long since regular Preventive maintenance was done?
Cheers

Why no accelerator control


Your throttle position sensor (TPS) is bad.

91 olds cutlass supreme runs rough and wont stay idle.


If your vehicle is fuel injected I would say you have a blown fuel regulator. This would cause excess fuel into the cylinders (flooding) causing a miss and coughing and also blow fuel into the air breather. If will also cause the vehicle to run poorly and could cause the vehicle to stall. Also to much fuel on startup can flood the cylinders and cause the vehicle to no start.

Hi i have a 2002 hyundai xg350l while driving the car accelerates without depressing the pedal further, in park when i reach 4000 rpm the rpm shoots up to about 4500 rpm without depressing the pedal...


I'd say sounds kinda like a missfire although with the absence of an engine code I would lean more towards a vacuum leak somewhere. Chk all your lines while cars running to see if you might have a vacuum leak.
