Title: Stored car for winter, now it runs terribly
Post by: Gooch on March 23, 2011, 11:06:13 PM

So I put my car away at the beginning of January outside under a car cover until this past weekend.  The car was running great when I put it away.  Fast forward to this weekend when I tried to start it up.  It ran like shit; searching for idle and stalling out.

I was completely surprised because I wasn't expecting this at all.  Looking over things I noticed my intake boot was torn in multiple places very badly.  Okay, so it was a massive vacuum leak.  I ordered a new intake boot from Blunt (which arrived the NEXT day, thanks Blunt!!) installed it and thought for sure it would fix the problem.  It didn't.  WTF?!?

Stomp test indicated 1215;

MAF Fault: The mass air flow sensor measures the  amount of air that is currently being drawn into the engine.  A big hole  in one of your fuel injection intake boots may cause the car to stall  and generate this code.

Alright, so I thought I fixed this with the new intake boot...so I swapped in a spare AFM I had laying around.  No dice.

I'm kind of at a loss here.  For some background, this past summer I replaced the fuel pump with a TRE 255 LPH, new fuel filter, new CPS, cleaned the ICV, and completed the "mess under the intake".  So I honestly have no idea what the deal is here.

Any help, suggestions, or ideas are much appreciated.  Thanks, guys.

Sounds like maybe some mice got to it? Check your wiring, etc.

Figured it out...feel like an idiot.

The intake boot has two open bungs on the bottom, one for the ICV vacuum line and the other isn't used on our cars.  Not even realizing (and assuming it was plugged from the factory) I put on the intake boot with the open hole on the bottom.  After I finally realized, I grabbed the old boot from the bottom and sure enough there was a plug pressed in there.  Popped it in the new boot and all is well.

I should have thought about that. I just replaced mine and was in a panic because there were two holes in the bottom and I had one hose...
