Norm, if I take the brake booster hose off it sputters and dies like it should. It's the MAF sensor that I can take off with no difference.

In a post a few pages back there was a picture of your engine with a breather filter were the oil cap goes
Could that be the leak I know when I had my. Car at ADM Andy told me my tune would need to be changed if I wanted to use one of those could that be your problem just throwing it out there |

Ahhhhhh wonder if your speed density tuned. Now I've heard of this, but not exactly sure how it works. But I do think it takes the MAF out of the equation. Maybe thats why there's no change when its off. I hope you get it right Randy.

when he disconnects the MAF it idles the same but when he tries to rev the motor it hesitates... so I'm thinking the MAF is at least partially working correctly.

Well, then it's working. Remember when the car would die after a couple of minutes due to the hose collapsing? Wonder if something similar is happening but in a different location. Just enough to make it sputter, maybe?

Wait a second, disconnecting the MAF doesnt throw the CEL either? Thats not right, unless it was tuned out. But that leads me to believe there is more going on here than thought...
If the MAF is not right, then the computer is trying to compensate to make things happy. So then the fuel trims are all outta whack. Got someone close by to swap one with real quick? We'll find this SOB! J

Well I didn't have time to read the whole thread....but as a side note...I use wd40 instead of carb cleaner to find a vacuum leak. It's less flammable and doesn't dry stuff out like carb cleaner. Sorry if someone else posted this

He did. No codes. Very confusing. Randy, all your injectors seated and electrical connections on them tight? How much boost do you guys run with a Magnuson supercharger? Is it adjustable? Does boost stay steady or should it fluctuate as you drive? Does boost reflect on how much additional fuel is needed/used? I just ask cause if Mike at Vengeance said air leak, could it be on the fuel rail? Sort of sounds like your engine is starving at idle

Since Chris was here it gave me an idear.....
Why is your intake tube capped right before the throttle body and Chris' isn't? Where does Chris' tube run and what do you have there in it's place? According to this schematic, that capped off piece on your intake should have a hose running to the rocker cover. Looks like Chris is running a hose from there. Just wondering why yours wouldn't have that.

I'm done for a while messing with it. I'm wore out with it. Spent 600.00 on a tune and got nothing. I've been to a number of shops and experts now and they seem to all be the same. I'm taking a break. It's still fast. |
