I also had trouble (several times) with their Dual Sync distributors.... (I was an early adopter - too early as it turns out  ) which was the major reason I stopped using Accel and switched to the non cam signal EZ EFI... Seems that OIL can get up inside the distributor and cause all manor of issues -- PARTICULARLY if you have laid the distributor on it's SIDE after it's been installed etc - so it has oil on it.... A simple disassembly and cleaning was all it needed and bingo - it was fine again. |
I didn't think about the tps getting hit with the shock wave of the backfire and throwing it off. I will have to reset the values and see if it changes ? Could be as simple as that or I need a new one?
I got to talk to Mark today and he is going to look at my datalogs for clues and it was also discussed that the map sensor could be scewed also.
After going thru some of my datalogs I found that there is a spike that happens when I shift that goes to 17.25 a/f which isn't good. Last for a blip of a backfire it seems if all is just right.
Good thing is it still starts and runs good to 5500.
I'll keep you posted as to what happens. Another time at bat and I hope it gets better just like it did last time. If it was in the cards I would put a Fast or Holley EFI on it and let it self tune itself but i just am not up to the whole change over yet.
Thanks , Jim
