I finally got my MPFI L31 intake swap running after a hell of a time and even now I'm having problems. If I let it cool down it starts up almost instantly and runs fine, I drive it around and it drives good then I come home and park it and it wont start back up till it cools off again. I have tried adjusting startup spark at the temps it does it at, as well as crank BPW, I have been trying all afternoon adjusting both of those in both directions. I have even tried more crank BPW when warmer than cooler, opposite of what you expect.
Is it possible for the timing to be right but the disty still be off, like throwing the DRP out of wack or something?
