    Get this guys, I'm gettin my 95 GT ready for nitrous and when i took my timing back to 10 degrees... I've got cylinder misfires in 1-4 but cylinders 5-8 are fine. Its a new ignition set up, MSD yada yada. Ohmed out the O2's and there the same. Any ideas guys? Need major help, won't spray the car until i get it fixed.

    Did you buy your MSD brand new? Becuase I have heard of lots of MSD units failing. That is weird.

    Yea man its all new stuff. The reason I'm having troubles blaming the MSD is becuase its only cylinders 1-4..... 5-8 run fine. Possibly a PIP? I'm not sure. Continuing to do research. Thanks matt

    No idea about this MSD, but my suggestion is don't touch your timing, get the nitrous installed and take it to a good dyno/tune shop. Tell them what's going on and let them do the work, it's something you don't wanna fuck up heh.

    Just like anyone else, i hate giving my baby to a tune shop. That will be my last resort if i can't figure anything out. But yea, im gonna put my timing back to where it was becuase the computer should take care or most of the detonation. Thanx for the input

    What is the lobe seperation on the cam?? That will have a big effect on the giggle gas with a after market cam. Take your car to MD Motorsports for the tune Ken Bjonnes is the shit when it comes to tuning he tuned my car he is a great guy to deal with. Hell they are in 5.0 magazine almost every other month.

    As far as the cam goes, its the stock duration and lift. I've been tweaking the timing the past few weeks and its startin to sound a little better. Gonna throw some NGK plugs in it and we'll see what happens.

    8) Yea buddy, hey I wouldn't have bought a sports car and not get the sports part out of it. It spends most of the time at the local road course and an occasional rice cooker. Imports...... :gtfo:

    KISS

    back to basics

    check the gap on the plugs, check spark at the missing plugs, check condition of wires ect

    after all that setup your timing where you want it to be N/A then back it off 1-1.5* for every 50hp of nitrous

    start off with a small shot once everything is running great like a 75 or so and then up it as you get more comforable

    I was going to mention the plugs and their gap. That's where I would go first.
