Problem- Need Help!

JJ-NISMO · 05-05-2012, 05:35 PM

This morning I washed my car from head to toe. I spent a lot of time washing the wheels, but never sprayed inside the engine bay.

Note: I have an AEM intake

I go to start the beast and the engine sputters and dies. I start it again and it sputters, barely making it into the garage.

First: I pulled off the bumper, removed the intake cones and let it dry. Now it starts, idles for a minute, bogs down on its own and dies.

I have pulled the MAF sensors and am drying them as well.

My question: WHAT ELSE SHOULD I DO and is an immediate oil change necessary?!?!

Thank you.

My guess would be the maf sensors got humid. I don't think there's any need for an oil change I doubt any water got in there. Drying the maf sensor should be all you need. I've seen it happen with intakes get humid and the car won't run right.

Update:

Dried the MAF sensors and same thing! Runs for thirty seconds, bogs and dies.

Any other advice?!?!?!

How long did you let your airfilters dry? Were they soaking wet? I know a few members on here ran into the same problem, they let the filters and MAF sensors dry over night and was fine the next day.

I just used CRC MAF cleaner and reinstalled the sensors. I also put the cones back on and disconnected the Negative terminal on the battery.

In 10 minutes, I will fire it up and let you guys know.

I have had the cones in front of a fan for about 4-5 hours so far.

she's running!

Bogged down a few times, but held on. Road test in a while.

Now my window wont roll up though?!?!

roll the window up manually, hold it in the "Up" position for 10 seconds after it reaches the top, repeat for the other side. Fixed.

Glad to hear everything is working. Keep us updated. Thats why I'm not really a fan of a "true" cold air intake.

UPDATE:

Got everything back together and it seems to be running strong. The one issue is that if I rev it, or am decelerating, the engine makes a slight knock at EXACTLY 1500 RPM.

It literally happens only at 1500. I had my friend ride and listen as well just to get a second opinion. I cannot figure out what could possibly cause that only at a specific RPM. When it happens, you can feel the knock it your but. The car hiccups.

Any ideas?
