I have an 86 Ram with a 318 and it has a lot of performance issues.
#1 - It missing a little under load despite a full tune up and a sound engine.
#2 - It seems to have the feeling a trans issues like it almost feels like it kicks down but the trans is sound and recently overhauled.
#3 - It lacks power even for an 86 2bbl.
First should I ditch the logic module/computer and go with an aftermarket carb and ignition? how did I work the lock up converter if I do? Or could I have things like the EGR opening at the wrong time or a vacuum issue? Any help would be appreciated. The truck only has 60k on it but was sitting a while before I started driving it. Dump the computer and retrofit an electronic ignition. You'll need a new distributor with advance mechanisms, that's about all the computer did anyway. The converter is not controlled by computer, no worries about that.

I just recalled those carbs were jetted insanely lean, led to burned exhaust valves. The carbon canister is failure prone, carbon pellets can enter the float bowl and are just the right size to plug the main jets. I used to use a fuel filter in the vent line to keep debris out of the carburetor.

I had an 88 Ramcharger. It starting running like poo poo. It was the hall effect distributor. It ran good after that, but even better when I ditched the EGR, smog pump and converter. The thing even managed 17mpg combined.
