Thread: Car seems like its gonna die, then bucks foward

When im sitting in traffic, just cruising pretty slow my car seems like it just gonna die, but then the rpms shoot up a little bit and it bucks forward. Its only when im giving it a little bit of gas, then i take my foot off. I have no idea what the cause is, but i do know that i have a knock sensor code and a code for the throttle position sensor. Could the TPS be the problem?

Yes

Thats it? Just get the sensor and I'm all set?

Maybe.

Fix your codes and see what the car does then.

Sounds like tps to me.
