    If I do the potentiometer trick to get ride of the missfire which is driving me INSANE :mad: .. and tune it with a SAFC so the fuel is set well is it a perment fix or risky. I dont have the money for a dsmlink since i just through 7000.00 on all the new things and motor. I do want to run the car this summer and take it to the track I didnt spend all this money to let it sit and wait till I can afford a dsmlink. PLease anyone with knowledge of this I really need the help also how bad is it to missfire I feel it and let go of the throttle and coast in netural for a sec and it goes away.

    Thanks in advance

    The guy who did my motor put it in for me today dont know if it is working or not. It was doing it so much I had to pull the pos terminal to reset the computer to take it to him. It went away for quite awhile when i did it last time see if it comes back after this. I will tell you tommorow. I havent loged it or wideband it yet will do that here tommorow also I dont think I will though cause he set me up kinda rich durring the breakin of the new motor but to make sure i will see if I can find someone around here with a logger they will let me use of someoone with a wideband. Is there any real downsides to this cause I dont have the cash for a dsmlink plus I have to find a 95 eprom and the car is a everday driver for me.Anyway thanks for the help any ideas on the whole idea of doing this ( BAD_GOOD)

    Thanks

    Wow this was a old thread to see pop up in my email.
    To answer you though yes it did fix the issue. I did recheck Fuel and needed a few tweaks nothing major mainly in the lower RPM . It did happen Maybe 1 or 2 times a year but just barley touched the knob to adjust and was fine. Guessing bumps in road. Good luck.
