Wouldn't you think it would throw a code for any of those? Or not necessarily?
I'd hate to just start throwing parts at it, but sounds like that's what I need to do. |

Before replacing parts I would do some additional cleaning and diagnostics, like doing a proper cleaning of the injectors, checking fuel pressure, etc.

my engine was shaking after i disconnected the battery.
Edit: nvm, it still shakes after a while of idle. Last edited by bail_w; 08-17-2013 at 09:50 PM. |

This. I've had rough idle and stumbling acceleration for a few weeks now, with the occasional P0300/P0301/302/303/304 and the odd P0171. Finally got tired of it stalling at intersections and pulled the TB off. Not unreasonably filthy overall, but enough had built up around the rim to prevent it from getting the right amount of air at idle, as well as some sticking when opening/closing. I disconnected everything but the coolant lines because the TB cleaner specifically said NOT to use it on forced induction systems. A few squirts of cleaner and a minute with a shop rag cleaned it right up. Idles just fine now and responds much better to pedal inputs.

My MAF looked clean as well but after spraying with MAF cleaner there was noticeable smoothness and more power felt. Those little silver wires are very sensitive it seems. What can't be seen with the naked eye, but is obviously there is amazing to me.
