Hello, I was getting the dreaded code 17 code. My car was bucking and surging under light throttle. I replaced the o2 sensor and all was well for a week. All of the sudden on my way home from work, it started doing it again!!!! What could this be? A defective o2 sensor? A bad ground somewhere? I replaced it with a single wire sensor that I had shipped to me from "oxygensensors.com" I did some searches and it seems that a lot of people had bought them with success. SOMEONE PLEASE HELP. This is driving me nuts!! thanks, mike

 

oh man, someone has to have this knowledge!!

 

um whats done to your car... give us a list of mods... mileage... what vacuum you pull at idle... it will help you get answers.

 

ok, all it has is a pettit intake. I think I pull 12 hg at idle

 

oh oh, Unless you got a monster port, you might need a rebuild soon. How is your car running? auto or manual?

 

The car runs like a champ. It doesnt blow smoke in the morning, runs 12-8-10 boost pattern, and its an auto. IT has 69k on it and the motor was replace about 15k ago.

 

12hg at idle is REALLY crappy... you should be pulling 20-16hg .. i have a monster port job on mine and i can pull 18-16hg..

i'd check for some vacuum leaks, they could be a culprit... do you have a lumpy idle?
