thank you for posting this. I never once gave a second thought to it but while trying to do a log on mine I noticed a bias on the right bank. Did a smoke test, sure enough leaks everywhere that I didn't work on. Odd. Usually it's me screwing stuff up. Unfortunately it also means that I will probably have to buy a set of headers. Always something.

Re: Misfire at low loads
I didnt check the trims when i started. this definitely isnt a small miss. if im 5th gear it bucks so hard that it feels like its going to break rearend! i finally got everything to install the 90m lightning maf. so im going to start with a fresh tune. im hoping the issue is in my current tune. if not then back to troubleshooting. one more thing to note, during acceleration with around half throttle it goes really rich to around 11.0 then leans back out to whats commanded.Brewster wrote: ↑2021 Jun 14, 22:54 Still haven't had a chance to finish this one, customer opted to come grab his car and replace his intake manifold himself. When he's done with that I'm sure he ll bring it back and I can continue onward and upward.
I've noticed any cammed fox's I've played with usually have a bit of a miss while cruising or low loads. I've always inspected the ignition systems and never find any issues there, not sure if there just running a little lean and don't like it, a characteristic with a cam or what it could be.
Hows your trims when yours starts messing around?
