Vehicle “surges” at idle. 300-500 rpms at a time. Sometimes the brakes hold and sometimes not. Have nearly been in 3 collisions the last 2 days because of this issue. The ecm codes indicate throttle body or tps issue, both of which have been unfounded. Vehicle has 63,000 miles.   Read details...

The Other Fuel System Hoses Lines/piping, And Fittings problem

I noticed the odor of fuel as soon as I exited the car and checked to make sure I had secured the gas cap, which I had.   Read details...
