Do you have the same code set?
I have no codes at the moment. When I took it to the shop 2 weeks ago they must have cleared it, but I have no CEL now.
I ordered one of those Bluetooth OBDII dongles, so I can use my android phone as a code reader. I wanted to use that to watch the TPS. I'm thinking that would tell me if the throttle is actually moving or if something else is causing the surging (like a leak). Is my logic on that correct?
