I have a 1987 Dodge Ram 1/2 ton w/a 318. It has an Edelbrock 600 4 Barrel Carb, and I had it timed at a shop about a month ago. It has been driving fine for about a month, up until yesterday. I drove to town and was heading back, about 8 miles total, and it acted like it was barely getting enough gas just to stay running, but BARELY. I pulled over, tried starting it, and got nothing but it trying to turn over. I took the air filter off and put a couple drops of gas in (what i had in the can), and it cranked right up and got me home. Anyways, I was driving to work this morning, it ran fine up until i got to the highway. I got about 55 mph, and it started popping or coughing, and losing power, it kinda felt like the tranny was slipping but it wasnt. It just seemed like it wasn't getting enough gas, but i have half a tank, and someone told me it could be the backflows screen into the tank thats clogged? I haven't changed the fuel pump so that could be it, but i've seen lots of similar problems and none of the solutions were the fuel pump. Anybody have any suggestions? I adjusted the carb myself with no knowledge except adjusting a 1 barrel, and it's been running fine like that for about a month, so i don't think its the carb adjustments.

 

have you checked the fuel filters?

 

Timing maybe? or clogged cat?

 

I don't think its the timing, and the fuel filter is good, are there 2 fuel filters? No cats

 

Since the truck is not stock there is no way for us to tell how many fuel filters are on your truck. Run the fuel line to be sure you know how many fuel filters are in the line.
