car is misfiring nasty style at anything under 35-40% throttle.

MAF just suddenly reads 0hz? That can't be good. Harness problem? Bad MAF? Swap it for another MAF and see if the problem continues?

I've got a stock LS1 MAF if that helps @ all....

i dont think that maf will help me. and im not sure if i have a newer style maf lying around.

im going to take it out now, along with my afc and clean it and try to see if possibly my afc has water in it or something or something

but yeah

cant be good. would explain why its running like shit tho.

 

[Eagle]

Sure would

here check it

the bottom most line on the chart is maf in hz.... see how it starts to fluctuate and goes to "0" every now and then.

Thats definitely bad. You gotta bad MAF and I'll bet your VE table is FUBAR for your application, so anytime it fails the VE table is what the car is running by...

Just figure out that MAF thingy and get back to tearin it up!

i have a brand new delco maf if you need one....

 

[Yaj Yak]

alright sweet. ill let you know if i do. im sorry i havent gotten those speakers to you yet- my lil brothers yukon is blocking all of my stuff in my garage, and its broken and i cant get it out... once i get it out i will ship them. so sorry it has taken so long.

 

[Yaj Yak]

heres another view from a different scan... look at how i give it gas- and it eventually comes back...

skip the cleaner and use the qtip method to clean it. Sounds like it is way out.
get someone to tap on the top of the maf while the cars running and see if it changes on your scans .

 

[Yaj Yak]

it is way out or on its way out?

also... if it changes when I tap on it... whats it mean

 

[Sinister Drag Designs]

on its way out. sorry.
when you tap it, it should change/jump a bit. this is a normal response. Non responsive mafs tend to be shot or not reading correctly.

 

[Yaj Yak]

alright cool.

It definitely seems to have been for the better though that this is all happening since when I removed my engine cover, I noticed a slight fuel smell, and noticed that my front center injector was leaking from the rail...
