I've searched the forum to see if I could find a previous post that would solve my issue, but nothing seems to match.
My 64.5, 260V8 starts fine and idles fine, but hesitates badly on acceleration. I've replaced the plugs, wires, distributor cap, rotor, pertronix ignition (now a pertronix II), ignition coil, fuel pump, fuel filter, rebuilt the carburetor, adjusted the accelerator pump, adjusted the timing and yet I still have hesitation on acceleration. When I step on the gas, it's like I just took my foot off the accelerator for a few seconds and then it picks up... not smoothly, but it begins to accelerate ok.
The problem started after the car sat in my garage for a year. I think I ran it maybe 2-3 times over the year. Back in the spring, I was determined to bring it back to its old "glory". At that time, I noticed the fuel line was clogged as I could not start it. I blew out the fuel line with compressed air and got it started. So far so good, but then I noticed the hesitation. So, that's when I started to do all the work I mentioned above to no avail.
What do you think? Maybe crud in the tank? I've used a few tanks of gas since. Vacuum leak? Something else? I love working on this stang of mine, but this is frustrating! Any ideas?
Thanks,
Jim
