Tech Help. I hit the trifecta.

car hesitates now so I go to Advance and get the cel checked:

P0507 - Idle Control System RPM High

P1170 - Manufacturer Control Fuel Air Metering

P0420 - Catalyst Efficiency Below Threshold (Bank1)

Maybe one problem is causing all three codes, dunno. Anyone want to take a stab at it.

i had that same problem with my car when I first got it. So I pumped a load of injector cleaner and fuel sytem cleaner into it for like two weeks. Then I changed the spark plugs, wires and coil packs. Still nothing. Then it went on for like another two weeks and all of a sudden it just stopped one day. Hmm. I now realize telling you all of this was absolutely no help to you. *IDIOT!!!*

Dont you have a standalone ecu?
Did you always have cel or is it recent.

tried that

Just keep throwing parts at it until you fix it. Or spend 75bux and get it properly diagnoised.

I threw in the towel. I'm just gonna wait and have MP Nick mess with it in March.

Whats the production date of your maf sensor?

 

[Witchdoktor]

I'm on MAF #4 and yes I tried that too

Did you dump some water on top of the intake manifold (intake manifold to head connection) while the engine is running?

 

[Witchdoktor]

nope

 

[BlkZoomZoom]

Go try it. Engine idling dump a bottle of water where the injectors are and listen for any slurping noises.

 

[Witchdoktor]

if it does slurp what would that mean ?

 

[BlkZoomZoom]

Your intake gasket is not sealing, causing idle problems and lean condition.

Vac Leak...

Vac Leak...

did a smoke test, wasn't a leak

 

[BlkZoomZoom]

Did you try what I said?

Checking the trusty protege online manual

The only thing thats common between them is a vac leak, or a pcm malfunction (that would suck).
