91 Stealth R/T Intake

So I bought a after market intake and unfortunately I have a MASS, my problem was my MASS adapter fit perfectly but the other side of the MASS was shaped like a huge oval that only a 4" to 3" plumping fitting fitted too. Now I got it all togeather it 90's out of my intake and then 90's again to sit right by my battery. I reset my ECU by removing the + terminal from the battery and now my car runs like crap. Hit the gas and it is very spontaneous and wants to stall a lot. Any pointers on what I could of done wrong?

check to see that your MAS is plugged in.

The problem was simple, with the after-market piping I was getting more air then fuel so I switched to my stock piping {ugly but works)and it still gives me the desired affect. Before anyone asks I did reset my ECU with the after-market piping installed.

there's no reason to reset your ECU when installing an intake. tell me, was this intake just a filter? the pipe/tube? or both? was there a vacuum port on the intake tube?

its really a simple install; i'm sure you just accidentally overlooked or forgot to plug something in. i'm a bit confused by your first post, but it seems like you first had a fitment problem where unfiltered or unmetered air was leaking into the system. then you fixed that problem with the 90 degree bends, but it should have worked fine at that point.

if you could post a picture, i'm sure we could get it all straightened out.

welcome to AF!

word of advice, when your disconnecting your battery, unplug the negative terminal first and always connect the negative terminal last.

And yea, i don't understand what your saying about whats wrong, but as linebcker said post a picture
