It seems like my car does this randomly like at start, highway, normal driving, and sometimes it'll be fine for a few days.

When the TCS and SLIP light comes on, and i make a complete stop then start to release the brake the car vibrates heavily. I can feel it through the seat itself and passengers also feel it. My 2000 SE (auto) is going on 150,000 miles so I dont know what the hell is going on, But Im guessing the tranny is going....(Sigh). This started about a week ago. My mechanic did a diagnostics on it and no codes come up pertaining to this. Any help would be appreciated.

 

i got that right before one of my coil went

but then again i got a SEL right after

 

its definately the ignition coils. Change all six, call Dave B at 888-254-6060.

 

Thanks a mil.

 

just to add some more input, i was having this EXACT same symptom. the TCS, Slip, and ABS lights were on, and when i braked the car would shudder heavily and was difficult to stop. it turned out it was a rear ABS sensor, and the dealer replaced it and it was back to normal again.

but you have a '00, it seems these symptoms for whatever reason end up being the coils more than the sensor, but just adding more info for others, especially 5.5 gen guys.

 

When my car this it was also my ABS sensors. So dont count on the coils, inspect the ABS wires first and make sure they are not damaged.

PS- they are the only black electrical wire in each wheel well running to your brakes.

 

Thanks again
