Customer Question
my cars been running rough...
my cars been running rough for sometime. and when idling the engine would surge then go back too normal. I took it for a drive and when i floored it the car would jerk and stutter a bit. Well just today i went too start it up the engine was idling really high then the check engine light came.. after about 5 too 8 mins the light went off i had too shut the car off because it was too idliling too high. I did however get the code.. i did it the old fashion way i turned the key on put a paperclip in the code reader the fan turned on and the engine light blink 12 3 times.. then it went 11 11 for 22. if you have anything there could you check the code? i found throttle sensor. i start the car every other day and the check engine light never comes on intill today the other days the car would always start rough and idle kinda rough.. but today just idled really high never seen it like that before. but a few months ago when driving it... the engine was idling high in fact i had my foot on the brke and car was moving a bit. kinda scary. I shut the car off at theat time reastarted it and it was fine.. but still had the studder or jerking when the pedal was floored.

if this had a code 22 in it which is a TPS sensor code and would cause this issue you are having

the best bet is to be sure the TPS electrical connector is tight and the wires visually to the TPS sensor look good if they do replacing the TPS sensor should correct this issue you are having

if you have any questions please ask as i do not get credit for my work until you rate me here at Justanswer

yeah it was kinda scary hearing idle that high like the car was going too take off. would the rough running and pedal too the floor the studder/jerking be about of this also? any other symptoms with this?
Buick Mechanic: Gary, Buick Technician replied 2 years ago

yes if the TPS is bad or giving a bad signal it will over fuel or under fuel the engine and cause this issue

Is there any kind of adjusting of the sensor that would be needed?
Buick Mechanic: Gary, Buick Technician replied 2 years ago

yes once in place a scan tool needs to be connected to the cars OBD port and the TPS set to 25 to 60 at rest

or if no scan tool put the new one in the same location as the old one was

Customer reply replied 2 years ago
