HELP!!!!!!!!!!!!!!!!!!!!!! Intermittent hell!
I need some serious help. I have a 1962 Galaxie 500 with a 390ci FE motor. I've had the car for 7 months now. It has had no problems except for a vacuum leak under the carb spacer. It was missing a gasket. Also I had to replace a crack exhaust manifold as soon as I purchased the car. Other then that it has been an excellent running car. However, last thursday I was driving my car, when is started overheating for no good reason...right before this it started to bog down, in 1st and 2nd gear but then it planed out.
I changed the oil and the thremostat, finding no reason for the overheat. Start the car, oil pressure 50..engine temp 185.. it ran great until I got where I was going. Then when I start it up again it idles rough and bogs down in 1st and 2nd under 40 mph, over that I'm smooth as can be.
So I think its bad fuel...change the fuel filter and clean out the carb, replace a carb gasket. SAME DAMN THING! Runs great until I turn it off...turn it on again, its a mess! o.p. 50 engine temp..185
Now I think its electrical...maybe a coil going bad..you know heating up. I change the coil..check the points and condenser. They look good. This time I start it up and let it heat up to 185-190. Then I drive it..it drives SMOOTH AS CAN BE! I drive it for about 4 miles. Come home, turn it off. Let it sit for 5 minutes and then fire it back up...This time I CANT EVEN GET AROUND THE BLOCK...its idling really rough, and bogging down likes it fuel starved. Its bucking a little. It stalls on me, ...its starts right up, but I have to ride the gas the whole way home. WHAT IS GOING ON! The plugs look good...the plug wires where just changed, the points and condenser where changed 3 months ago, the carb was rebuildt 3 months ago. The coil was just changed, the fuel filter was just changed. UGH!
A buddy suggested it may be vapor lock in the fuel line..maybe to close to the exhaust. I traced it, the closest it gets to the exhaust is maybe 5 inches. I dont think thats it. WHAT CAN IT BE? Why will it run fine until I turn it off, then run like shit again when I fire it up. I ran it without the gas cap..same thing...then I change the condenser, plugs and plug wires again! Same thing. So confused. Can anybody help?
Its a 1962 Galaxie 500 with a 390FE and the stock ford 4 barrel carb (I think its a holley)
Any help is GREATLY appreciated.
