I rebuilt my 1986 S-10 Blazer 4x4(2.8L TBI.A/T.) No error codes, starts every time, purrs like a kitten. Takes off w/ok speed then in 2nd & 3rd feels like i'm pulling a house. I have to hold down the throttle to maintain speed on inclines which causes overheating. Slows to 25 mph on bigger hills. on level ground it travels ok. w/nt climb to highway speed. Seems to be using a lot of fuel. dealer test only ckd engine @ idle. of course no problems found. STUMPED. PLZ HELP.
