hey guys, been a long time since ive been on here but i have some problems.

FIRST.i had a gmpp stage 2 installed about 2 years ago. during the summer months it seems to be ok, but i have smelt the smoke during hot summer days but have never noticed any. now that its later in the fall every time i start my car when cold and step it down a little in first of second it smokes like the engine is shot BUT its black so it seems to be flooding like a SOB. is this because of the larger injectors in the cold dumping so much extra fuel?

SECOND
everyone knows about water/intake troubles, theres even gm bulletins to prove it. but mines been getting worse in the beginning it was small bucks. now its engine nearly stalling throwing me into the steering wheel bucks. and engine running like crap and making be rev the **** out of it to get it to run properly again.

im running a injen intake with a clean filter and a K&N watershield.

everytime it rains and bucks a couple times the engine light comes on. everytime that i have checked it its been Mass air sensor. when it drys, light goes out. what the hell can i do?


on another side note, anyone have trouble with resonators? mine has something loose inside and is making a terrible noise.


thanks in advance!!

Check the intake pipe for holes, some have had it rub on the metal enough to create a hole and it suck in water there, also clean the MAF while you're at it.

As for the GMS2 it's notoriously rich, why it's worse all of a sudden I don't know but it could have to do with water getting on the MAF.

ok ill check into that. but what actually makes it buck? is it water actually getting into the cylinder and killing the fire or is it water hitting a sensor?

I honestly don't know, hopefully this bumps it for someone that does know.
