Need help with diagnosing problem
Posted: Thu Nov 21, 2013 9:14
Last week driving the protégé it was doing fine but I shift from 1st to 2nd after a red light and I feel the car go no were, I mash the pedal and got nothing, drove home and the car started to idle like shit and did not wana drive.
I just started it up again and idles like shit, id rev it to about 4k and it would rev like it had a misfire but a really bad one even though the car has new plugs and coils etc etc, I also checked for vacuum leaks by spraying carb cleaner all around the lines while it idle ok and I got nothing, next I thought my egr but I just replaced it. decided to take my plugs out and #### they were as white as snow! I then replaced them with a different set started it up and 5 seconds of crap idle and it would die.
so after all these attempts I hooked up a matco tool I have a read all the data while it was on fuel, timing, maf, and checked for codes,
only codes I got were oxygen sensors and intake manifold tuning valve but those have always been there.
What the hell could be wrong with the car?!?!?!
my last assumption was a batch of really bad gas
