1G crank pulley broken/ MAFT issues
 

**UPDATE** April 12

Crank pully rubber is gone. Alt/wp belt missing in action. The broken crank pully carved up my timing belt cover, too. Would this broken crank pully somehow have f-ed up my MAF? I dont see a connection, but ya never know. *Also, should I use a used crankpully I have or buy a new one?*

I'm a dumbass. Stopped at a light in the left turn lane, I wanted some sideways action in the rain today. Step on the gas, sideways I go, and CLUNK (probably crank pully exploding lol). The car jerks and sputters. Pull over. Car cranks fine, when it fires it wants to die. With the pedal floored doesn't go above 3k, or even stay there for long. It would rev very erratically. I disconnect my MAFT v. 1.6 and rehook the stock MAS and recirculate the BOV. I checked the IC pipes, wiggled hoses, looked everywhere, and didnt find anything weird. The car runs fine. What happened?!

Car has basic mods:
14b, fmic, 660s, 255hp, afpr, afc(5knob), maft, (not tuned, rich, doesnt knock), the rest isnt valid.

Re: Won't Rev Past 3K
 

maybe some mafdt wires got loose? Sounds like an MAS problem.

Re: Won't Rev Past 3K
 

thats what i figured, just need to pinpoint. I should add the LEDs on the MAFT were blinking... does that mean something? lol I dont know anything...

Re: Won't Rev Past 3K
 

If the led(s) were blinking it may be the rpm wire. It might of gotten knocked off.

I still wouldn't rule out a big boost leak until you are 100% sure that all your IC pipes are good to go. Sounds just like a boost leak to me. Either that or you are running on three cylinders from something.

CRAIG

It wasnt a boost leak. I was in the car and when after that happend we put on the 1g MAF and everything was fine boosted fine and everything. So I wouldnt think its a boost leak
