i just threw in the injector cleaner, it might help. but like i said i found a small vacuum leak from the boost nipple, and when i fixed it the problem improved quite a bit. i also ordered a new injector seal kit because i have a feeling my o-rings might be worn out

thanks for the info guys, ill look into the fuel filter, and cleaning the system, as well as cleaning out my maf sensor, i know its not my wiring job from doing the build cause the car was running beautifully before and was able to hit 14psi with no problems, so something has to have changed since the build was done, and with my old bumper water was able to get to my filter real easily and it was taking some in, which like before leads me to belive its a dirty maf sensor

See this is what gets me mine worked fine for the first few day then after that when ever I hit boost lots of misfire

c1_c1rca

Axelthered05

iTrader: (9)

I never fixed it I just gave up and returned to stock, really hitting myself now for not sticking with it and figuring it out

I have heard somthing interesting since though. when I went to the RKC super show last summer I had a conversation with some of the guys from GMTT who said using the LSJ parts caused problems and that using the stock 2.2 MAP and TB is best but in order to do so they said you needed to bore out the screw holes for the 2.2 TB to make it fit but that it would fit they also said to use the stock map you had to have vince tune the car to make it calculate the fuel using the MAF insted of the MAP so you only use the MAP at idle. one other thing they said was never to cut the wires but insted to unravle the harnes to reach the proper locations. Im not sure on weather or not this would help but I just thought It would be good to mention it. that would at least rule out some problems. also I just wanted to ask if you were using spark plugs one or two degrees colder? if so are they for your engine? I have heard using LSJ plugs also causes problems

Anyone have any other input or comments on any of this?

c1_c1rca

i have the one step colder plugs for the 2.2, and i did unravel the wires to reroute them.. and the only thing i cut was the throttle body harness cause i had to rewire from 6 pin to 8 pin, i didnt soder them but i used connectors and taped the **** out of it...

Axelthered05

go back and soder them it might not solve the problem but its always a good idea to make sure to secure the wireing and get some heatshrink on them not tape everything you need to do that you can get at radio shack

c1_c1rca

not a bad idea, also just went and tried to start the car to see what happens and holy **** i have no idea whats wrong with my car, cause i highly doubt that a dirty maf can do this....

make sure there are no leaks around the injector area,check the gaskets on them.What is your entire setup you used?

Axelthered05

iTrader: (9)

I would also like to know what your running

c1_c1rca

Eaton m62 blower, stage 2 pulley, 42# injectors, 1 step colder NGK spark plugs, K&N cold air intake, lsj intake mani, stock lsj h/e, trifecta tuned, stock 2.25" exhaust back to a 2.5" magnaflow muffler, and i have a ss/sc exhaust mani to install.. the gauge in the video was my boost gauge on top and in the middle is my interceptor but that didnt even get a chance to turn on and my wideband is on the bottom but is disconnected right now

your not by chance using NGK BKR7E are you? Because NGK BKR7E are for the LSJ. for the 2.2 you want one degree colder NGK LTR6IX-11 but they are more expensive you can get them from ottp
NGK Iridium IX Spark Plugs

Yes check for leaks, harness may b loose or not sittin right, buddy had the same issue n his actually came off

Axelthered05

iTrader: (9)

Corect me if i am wrong but I think the 42lb injectors are shorter than the stock injectors check for leaks around whare the injectors contact the head

My setup is almost similar to yours.Option b tank,42's, zzp stg 3 h/e,dual pass,stock dp and header and a tsudo exhaust.The only promblem Im having with mine is KR and my car stalls at a stop from a run.

i have 60 lb injectors for plug and play and i got a tb harness 6pin to 8 pin so there is no cutting and im using stock map sensor so by not having to rewire anything i hope those issues dont happen to me.

Axelthered05

iTrader: (9)

and what spark plugs are you using?

zerosk8ter83

iTrader: (3)

1step colder here

Axelthered05

iTrader: (9)

no im not asking how many degrees colder your using I want to know what the model number NGK your both are using

c1_c1rca

ill have to pull mine out to find out, mine came with the kit that i bought, but it was a piece together kit that came off an 05 ss/sc

Axelthered05

remember you should not use LSJ plugs with your builds, LSJ plugs are shorter and dont reach the proper length into the combustion chamber thats why I said in post 39 not to use NGK BKR7E spark plugs

c1_c1rca

yeah i remember reading that, im pretty sure they are not the lsj spark plugs but i want to replace them anyhow to make sure
