My tps went with no warning. Went to make a left across rush hour traffic. I got a break and nailed it and it was like sudden limp mode. Had to idle in second across the road and went to the shoulder. It never died but it was tricky getting home. It began running fine again but it went limp two more times in heavy traffic. I read the codes and replaced the tps. Turns out there were symptoms for about a year before it went but I didn't make the connection... jerky throttle at low speed, slightly erratic power and the ebrake would sometimes fail to engage. Everything was like new again with the better aftermarket tps. Craig
