Getting closer .. Hopefully lol. I replaced the leaking return o-rings... But I apparently bumped the one next to it because it started leaking lol. So I replaced those too , she's all dry now . I decided to just use a cheap gasser timing light with my meter instead of fixing the probe hole. Timing is at 9.5* . Smoke is completely gone! It still stumbles here and there.. And after driving it a mile or two it starts loping in gear. Switch to neutral or park it idles normal , back to drive / reverse and it lopes bad. It is definitely down on power. I'm going to throw a bottle of diesel treatment in the tank , since the truck did sit for like 10 years I'm sure there is junk in the tank. And toss another fuel filter on it. I ran the truck down passed 1/4 tank so I don't think the shower head broke off and clogged the fsv... But that will probably be what I check next .
