Question about 1966 Ford Mustang

2 Answers

I have a 1965 6 cylinder mustang and it was running well and recently I was driving and the car started to loose power. It seems like it does not have power i would press the gas and there was no response. I took it to the mechanic and they told me it was the carburator and I had the carburator rebuild by a professional and nothing. the car starts and when you press the gas it idles well then all of a sedden it starts to loose power and shakes. Once I take it out for a drive it drives well but once i want to spress the gas pedal it starts to shake and it doesn't respond.

What needs to be checked and verified is the point gap. And if it is adjusted to the correct dwell, the timing will need to be set again also. Oil inside the ditributor and contaminating the points as well as the condensor is not good. You probably has a bad seal in the distributor shaft,causing oil to creep up into the distributor. You have replaced everything else, so that rules out those components,therefor I would check or have someone check the distributor and point dwell setting.
By the way, points always become out of spec,and should be checked regularly.
Also check for a possible vacuum leak on any hoses; cracks or splits. I know there are not many on this year vehicle, so it should be an easy task.

Check the fuel pressure and fuel volume output of the fuel pump. The pump could be bad. You could also have a clogged fuel filter.

    I went ahead and bought a new fuel pump, coil, sparkplug wires and the carburator isnew and still nothing I checked the points inside the distributor and they were ok. i did notice that there was a small amount of oil once i removed the distributor capmaybe the distributor is bad and thats what is causing the problem?

  • dlinkhart Aug 24, 2010

    I would definitely check the fuel pressure and volume, even if you have replaced the fuel pump. There is a possibility that there is a restriction in the fuel system, or that the new pump is defective. With the car in neutral, will the engine run OK at all RPMs? Or does it break up at speeds above idle?

What causes my 1965 4 speed mustang to backfire and sometimes stall?

backfiring is ignition of the fuel mixture while an inlet valve is still open. Check firing order as there may be a HT lead crossed . If it backfires then the mixture is burnt in the inlet manifold so there is nothing left for the cylinders so it will stall. If you are running holley carby then check the power valve for a hole in the diaphram Check for vacuum leaks. check ignition timing is correct and not too far advanced. if the HT leads are touching each other this will induce a spark in the wrong cylinder --use lead spacers from an auto spares shop

1965 mustang the car starts and runs but when put into reverse or drive the car stalls this happened after i canged the spark plugs and replace all the wiring, i dont have very much experince on mustangs...

if automatic, look for vacuum hose damage/leaks or loose wires that may have come off during the work you did. Is the distributor a vacuum advance and are timing/ points set correctly?

Need spark plug wiring diagram for 1965 ford

Try this. If the distributor is in the right way, the clips that hold the cap on should be just a hair off of 12 o'clock and 6 o'clock. #1 is positioned at 1 o'clock, which is at the firewall side of the distributor. The firing order is 1-5-4-2-6-3-7-8and is counterclockwise from #1. The passenger's side is cylinders 1-2-3-4, from the front of the car. The driver's side is 5-6-7-8 from the front. Hope this will help.

Pulsating gas pedal in low speeds, if you go really easy on the pedal untill ~25, it will not pulse at all.

Make sure the carb is bolted tight to the manifold too. Loose nuts can cause this.
