Looking for advice here. At first I was getting a 1345 Ckp to Cmp correlation code. I was able to re-set the distributor forward a tooth and got the timing set at +1*. Light is off now but I still had a terrible cold start issue and a very bad stumble and miss at anything more then 10% throttle and more then 2000 rpms. I tested my fuel pressure and gauge was reading 50 idle and 57 open throttle. Also the pressure would bleed off drastically. So yesterday I replaced the pump and filter and now I’m at 52 psi and 60 open throttle.
Cold start went away entirely and pump on time to prime was drastically reduced. I can get the rpm’s up to about 3000 or so before it starts to hesitate and stumble and probably about 20% throttle but wide open it still falls on its face and starts popping through the intake which sounds like a lean mixture on a carb. So progress but far from perfect.
At this point I’m thinking the spider injection and the fpr is the issue and probably going to need a good tune up. What are some good plugs to use and the proper gap? All of the factory specs are saying .060 but that’s way too much I think. I think something in the .045 range would be better for response. Thank you for the advice.
