117828, Running lean
Posted by C L U T C H, Oct-15-07 01:54 PM
Last weekend i decided to clean my engine. I used the cleaning/ degreaser , and then rinsed everything with water. I removed the ecu, coil pack and the harness.

i let everything dry, and put everything together. the car started and everything seemed fine. Next morning i was on my way to school then the car was shacking stuttering and like dieing and when i press the pedal to the bottom it seems to accelerate good.

I scanned it and i got a PO171 cel (Fuel System Lean)
-->
MAP sensor output / Injector / Fuel pressure / Intake air leaks / Heated oxygen sensor / Adjust S-AFC

I think i was running with water in the spark plug holes. I dried it replace spark plug + wires (so i am broke now) car seems to be better but i still have to press the pedals to the bottom some time for it to accelerate

or i think there the map sensor broke due to water residue in the plug hole. Any suggestions appreciated

Did you pull all the plugs out crank the motor with the asd relays unplugged to get all the water out?

No, I used air to blow all the water out. maybe a few drops got in the cylinder but it's a few drops i think would be irrelevant, tell me if you think otherwise, And THANKS for the reply :) hmm

pull your injector harness plugs off, spray with WD-40. Reset ECU. most likely water in the harness shorting it out
