OK, I have the 8 injector setup, and it was roughly tuned for 12psi.

Lately the car seems to fall on its face right at 4K rpm. I can do a full pull through the rpm band in first, BUT 2nd-5th is when I run into the prob. Occasionally it will buck once, and then make a loud POP noise, and then continue to not pull hard.

Is this the result of the car pulling timing cause it is too lean?
Could this still occur in a too-rich situation?
Am I a retard? ( Dont answer this question, for I am sensitive :) )


I was also wondering if anyone is running the HRC inline fuel pump in conjunction with a Walbro 255 like I am? Would it be better to take out the inline and run just the Walbro?

U dont have anything to check your A/F or O2 Volts??? :(

Damn, i have the same problem, but i just installed my 8-injector setup and my wideband o2 sensor wires broke. So i am gonna order another from PLX and the try it again.First gear it pulls ok but the rest doesnt feel anything. I am waiting so, hopefully i can get it fixed. Good thread so i can get help, also.

Unfortunatley, I only have the blinky A/F gauge which is useless. I did have a datalogger, but my Palm died, and I ususally had problems connecting also.

Should I take out my inline pump since I have a Walbro? Does it matter?

Thanks

Are you getting any check engine lights? It was weird when I first put mine in it would stutter at 4krpm, but it doesn't do it anymore.

Maybe I should put my "check engine" light back in. OOOPS!!!


But it seems to be just recently that the car started acting up.
