Im new here and i need some help. I bought i 77 LTD with a 400 in it about a month ago. I know its not a truck but i figured someone would have some advice on my pos. The car's ran great since i bought it, but last night after about a half hour of driving, i floored her off a stop sign and she fell on her face. her new top speed is about 60mph and man does it take a while to get there. The car starts up great and idles fine but whenever i try and drive it, it's like im on five cylinders. I'm spoke to a mechanic and he told me it was probably something really simple, but im worried its and internal problem.
The car has new plugs, wires, fuel filter and pump. This has happened once before after being pretty hard on it, but i let it cool down for about 15 minutes and started driving again and it snapped right out of it. Please help.... i dont wanna scrap the boat just yet.
recheck your timing to make sure you didn't skip a tooth on the timing chain. just my opinion. Or check your vacuum advance on the dist. Someone who knows better will chime in soon.
Many Ford engines had a plastic tooth cam gear. The timing set is only good for about 80K miles reliably and almost always fails by 120K. If your engine has not had the timing chain replaced it may be time. Get an aftermarket timing set not an OEM type. See the multitude of threads here on retarded timing...
Good info Torque. Not to take away from that, as that is a good possiblility...but just wanna throw this out there...
In my experience, the heat related, and/or cooling off and it gets better, sounds like ignition...more specific, a control module!
I know, you would think a control module would fail completely, as would a timing gear...but, I'm sure you all have heard the old trick about cooling off an ignition module when it fails to get it working again,right???
I have had one fail, run rough etc..When I got to work I would put it in the cooler for a while and it would run fine until it got warm again!
My suggestion would be to try another module first ( can't hurt anyway ) before you go tearing down the front of the engine....although the timing gear is a good investment aswell!
another thing to look at besides the ignition module with a runs cold great but like poop hot is the much overlooked COIL!!
i can't count all the times i have had people calling with the same problem, and wasting money on a module to find out it was a coil breaking down from heat.
Hey thanks for all the advice.
put new cap, rotor, and coil in last night and problem solved. Coil never even crossed my mind but i guess that was the problem.
thanks again!
