My car: Hyundai Tiburon 2006 GT Automatic - 72,000 miles
This problem started 5/7. I was at a stoplight and my foot was on the brake. All of the sudden (while still on the brake) my car wanted to accelerate. Then all of the sudden the car shut off. I had to turn the ignition to off and then turn it back on and it started just fine.
I didn’t have any other problems until last week (6/2) and the past several days - at least once day - my car will be driving fine and then the accelerator will feel like it wants to go by itself. Then I brake and it feels like it still wants to accelerate. It also kind of sputters every so often.
I took it to a mechanic and he checked the throttle and there is nothing wrong with the throttle. So he disconnected the cruise control - thinking maybe it was switching on by itself. Nope, it has done the acceleration thing even with the disconnection.
I should add that I have had my check engine light on - it goes on and off every so often. Sometimes I can go for months without it coming on then other times it comes on all the time. I have had the codes checked and this is what the codes are showing: PO130 - O2 Sensor B1 S1 --however, I had that replaced and that code is still coming on!! And the other code is: PO118 - ENG Collant Temp Sensor Circuit High
I am at a loss??? What is the problem??? Why is my car accelerating by itself??? Can anyone help me figure out what is wrong??
