    Alright, I have a 92 plymouth laser turbo awd. Just last week I decided to swap out my old factory lower injector o-rings that I was using on my FIC 650's. Car ran pretty good before I took everything apart. I just wanted to have the correct o-rings with these injectors. So I go to start the car up and just idles like crap. Feels like it's missing. I cant hear any hissing coming from around the injectors. I let it warm up and took it for a small drive. Everything was going good then all of a sudden the whole car just shaking like it's missing BIG time. I come to a stop then let the car settle down. I take off it's good...I still haven't boosted, but this seems to happen all random. I have messed with my s-afc settings all over the place. Anywhere from -10 to -20's and nothing helps. I took the computer out of the car to take a look and see if any caps blew, but they are all good. Really stumped on what's going on. As far as fuel mods I have the FIC 650's, aeromotive fuel pressure regulator, walbro 255hp fuel pump, and safc2. I'am using a logger to watch stuff. I'am kind of wondering if maybe my wires are crap? I have 10mm magnacores and running ngk bpr7's plugs. When I took the plugs out they looked fine. 😞

      are those plugs too cold by any chance? i thought i heard magnacores are crappy? or were those other type of wires?

      At first I did it for fun, then I realized I made the investment and had to do it!

        I think they are aliright. Maybe not the best wires. Just the wierd thing though it all ran decent before this stuff. Even with the stage colder plugs.

          are you running a stock turbo with those mods then? what are the AFC settings? what is your FP set at?
