HELP NEEDED......

i am having problems with my car breaking up on the nitrous..the only shot i can use without detonation is a 75hp.. with a bigger than recomended fuel jet..i tried the 100 with the bigger fuel jet and the car still detonated..i pulled a couple of plugs and they were showing severely lean..but this problem has just occured within the past few days..any suggestions would be helpful..i am using a nx wet kit with ngk tr6 plugs gapped at 36 thousandths..
thanks in advance
patrick..

also it is breaking up on the motor at the top of third gear around 5200..the car just "falls on its face when it hits that rpm"..in other words im clueless and dont know where to even start so i would appreciate the help

Re: HELP NEEDED......

Year, make and miles on the car? It could be the fuel pump is on its way out and cant support the fuel needed. When was the last time the fuel filter was changed. It could be cloggged causing it to starve for fuel. When was the last time the injectors cleaned (if you have alot of miles). It could be that the injectors arent keeping up.

Either way, its a fuel issue. Can you check the fuel pressure? That will narrow it down pretty good.

Re: HELP NEEDED......

Autozone will loan you a fuel presure guage for free. All you have to do is screw it on to the fuel rail.

Re: HELP NEEDED......

Autozone, hell they'll hook it up and check the pressure while you rev the engine. It's easy and definately something with the fuel, not the fuel solenoid (he stated it does it NA also). Know anyone with Autotap? If so, have them log your car NA and spraying. Good-Luck.
