Hello everybody!
I am starting to get stuck with my ideas, and I has hoping someone might have an answer for me or help me with some diagnostics. I will tell you the issue I had, and I will tell you what I have done so far to fix the issue and what has cropped up since.
So here we go;
To start, the problem I was having with my truck was that when I was driving down the highway it would feel like a huge gust of wind was hitting the front of the truck slowing it down and then when the sensation was peaked the RPMs would fluctuate (jump up about 300-400 more)and then back to where it should be till the next time it would happen and it was happening only when I was at highway speeds with intervals being sporadic but often.
So what I had done at that point to try to fix the issue was
-Made sure I was getting a good fuel flow to carb.
-New timing chain and gears.
-New spark plugs (a cooler type plug).
-Electronic ignition.
-Made sure timing was good.
-Changed the transmission oil and filter.
Other things that were done too during the fix but for other reasons were
-The rear main seal.
-2 Frost plugs.
-The rear pinion seal.
This cleared up the issue of that wind gust feeling issue. Now I have cylinder 3 that does not seem to work. The engine wants to stall while in gear at a stop light or sign and in gear. When in park or neutral idling, it runs rough.
This is what I have tried to fix that with no luck yet.
-Made sure I had the firing order on the cap correct (lol it could happen)
-Swapped out the plug.
-Checked gapping on plugs.
-Changed wires.
-Changed rotor.
-Changed cap.
-Changed the vacuum lines.
-Sprayed WD40 around the 2bbl carb spacer to see if it would raise the RPMs but I could not detect any change (looking for a vacuum leak)
SO with all that said (I know it was an ear full or I guess more so an eye full lol) does anyone have any ideas of what I could do or try to help fix my engine in my truck.
I have the high energy coil that matches the ignition on order and should be in by the end of next week
If I ve left any important info out please ask and I will put it in and if I don't respond right away its because I will be in the middle of moving in the next few days so hang tight and I will be back online shortly.
The truck is a stock 1973 ford f100 with the 360ci, 2bbl carb.
