I'm Lost

[GTwolf]

Well I'm running lean to the point of throwing a "system too lean on bank one" code. Thought I had a bad MAF, replaced that, it helped a bit but the problem is definitely still there. If it helps it's idling like shit, and I'm getting about 12 MPG, the DIC say 16, but theres no way. And that's driving it nice too and staying out of boost. I was thinking possibly front o2...but wouldn't that be throwing a code? Or maybe a vac leak? I had this problem right after the swap and it turned out the supercharger gasket didn't seal right and there was a giant vacuum leak. Or could there be a problem with the tune? Idk, I'm lost, any ideas?

im reaaaallly thinking vacuum leak.



vac leak vac leak vac leak.

im betting that whole s/c gasket part... vac leak...

Yeah, we replaced the gasket (for the second time in a week), but he said to try and seal it without RTV...maybe that didn't work out so well.

all ur vac lines are good ?

 

[GTwolf]

I think so, one of them was destroyed, but I already fixed that one. I'll check again though, I don't have my car with me right now, but I can take a look in the morning. No school tomorrow, so I'll have the whole morning to look around.

Do you have an IC? Also, ALWAYS use RTV on SC gasket...yeah, yeah I know it's not "needed"....but 75% of the time a dry install leaks...and a motor with performance in mind (aka more boost) will blow out the gasket that's only designed for 7-8 lbs boost.

I like to put a light even coat of black rtv on both sides of the gasket...let it hang until tacky, then install.

Yeah I'm making about 10 PSI so I guess I should re-do it with RTV. Can I reuse this one or do I need a new gasket?
No I don't have an IC unfortunately.

No I don't have an IC unfortunately.

I asked because the bolt that holds the bracket for the MAP will pop up the blower off an IC if you try to re-use the stock bolt.

Well, update, can't find a leak in the lines anywhere, so I think it might be that gasket giving me shit again.
