Question about 2001 Chevrolet Malibu
2003 Chevy Malibu - 1st problem was that on long trips the car would not decelerate when wanted to slow down. If I stopped it would be revved up and once I got on the road again it would accelerate without me even touching the gas pedal. Drove through Houston, Tx like this and aged 10 years. This would only happen on longer trips > 2 hrs.
Now the car wakes up accelerated. When I turn it on first thing in the morning it is highly accelerated with the rpm gage at around 3 when it usually idles at a 1. If I attempt to drive it stays at about 30-25 mph without me even touching the gas pedal.
I have taken it to several mechanics without any success. They have done a tune up and fuel system flush. They suggested some valve might be sticking but they can't seem to diagnose it.
Any help to point the mechanics in the right direction would help.
Throttle position sensor. It's under recall for most Malibu models.

RUN A OBD 2 CODE TEST FOR ANY STORED TROUBLE CODES, KRAGEN AUTO DOES THIS FRO FREE AS WELL AS OTHER CHAIN STORES LIKE KRAGEN, THEN CHECK 2 THINGS, THE IDLE SPEED CONTROL VALVE, IT MAY BE STICKING DUE TO SLUDGE BUILD UP, CLEAN IT, IF HIGH IDLE IS STILL AN ISSUE REPLACE IT, THE NEXT IS CHECK THE THROTTLE POSITION SENSOR, THE SIGNAL RETURN VOLTAGE SHOULD BE ABOUT 1.0-1.25 VOLTS WITH THE THROTTLE CLOSED, CHECK WHEN THE IDLE IS HIGH, IF THE VOLTAGE IS HIGHER THAN ABOVE SPEC REPLACE THE SENSOR.
