Hey everyone. My situation is not as common as some but I'll fill you in. I have a 95 Mark viii motor and trans in my 1967 f100. I used the factory computer and wiring. I'm using a walbro gss342 (I believe). 255lph pump with a fuel cell. Truck ran great. I notice though that if the truck is cold, towards fall, it will spit and snap and sound harsh at first. A couple minutes down the road and it seems to clear up. I have had issues under hard acceleration where it will stumble. It has all new 02's. Maf sensor cleaned, new temp senders etc. I tested fuel pressure yesterday and it was 32 at idle and 41 with the regulator unplugged. I'm finding differing info for the fuel pressure at idle and revving. Can anyone steer me in the right direction? Thanks!
