I give it gas, it boggs down
 

Ok so i new i needed a new alternator so i drove out to my buddys house and installed a new alternator. When i drove out there i had no problem at all. After done installing the alternator my battery light went off. Everything seemed to be ok. Well when i started taking off my car would bogg down like it was not getting gas. NOw when i start it up it will bogg down and will not pick up rpms. Then it kinda sounds like its farting and a little black smoke will come out. I tested my compression and checked my turbo to make sure its not locked up, and i got perfect compression and no oil in turbo. I also checked my spark plugs and wires. All good. So i have no clue on what is going on now. I just had a 6bolt installed and really have not had to many major issues untill now. Any clue as to what is going on would be really helpfull. Thanks all. ~96 gsx awd~:KANE:

Make sure the plug wires are on the right cylinders and that an intercooler pipe isn't off or the MAS is unplugged.

i put a data logger on it and it gave me a mas error and o2 error. I just had a brand new 02 sensor put in. Should i try replacing the mas with another just to see it if it fixes it? any other things i should try????

I had this same problem, but I forgot to plug m mas back in :( its probably somthing minor....Boost leak check?
