Hey, I am new here and I am getting 5km per liter. which i dont know what that is in mpg. But it isnt good! I am sick of dumping gas into this pig.

I bought it back in january. didnt notice till after that it drank gas, and had no power. So i got the timing changed. It was at like 8 degrees out i think. But know its back at 0 i think. The truck had a bad bog as soon as it warmed up. So i changed the TPS and ECTS. Nothing. So brought it to a shop, and they unplugged the EGR. They said i need a new one. But the mechanic has the same truck and said he bypassed it. that fixed the bog, but its no better on gas. I cut off the cat, and gained alot of power, but no mileage gain. We changed the distributer and wires. and rotor and cap and what not, fuel filter and air filter.

It throws no codes. it supposed to have a new motor and tranny when i bought it. I assume its still a 350. I dont know what else to check. Im just getting into trucks, and dont know much about this sort of stuff.

I ran 1 container of injector cleaner threw it, but nothing, that was a while back however. I still think it may be injectors because. If i leave the truck for a few hours. it takes a few cranks for it to start. but if its only off for a few minutes. it will fire back up instantly. Could it be slowly flooding itself?

Thanks, Mark

on these trucks with TBI set right running fine the only thing that matters the most on economy is your right foot. my neighbor pulls his trailer grossing 25K with a 91 350 4 speed and still gets 7

OP, let's clarify what's sending spark to the plugs on that 1967 engine. Is it standard distributor with points and condenser, HEI, computerized, or what?
