Why does my 1964 ford fairlane 500 3 speed manual trans. Run rough when not under load.


Hey Fred, I AM SOOOOO JEALOUS!!! My teenage years Saturday nights were spent in a 64 Fairlane...(4 speed - 390 - WOW!!)..
Any way.. your carb needs some TLC, a valve clearance setting-get a qualified pro to do this!!), new spark plugs (wires maybe) .. a new air filter.... mainly the carb needs a QUALIFIED PROFESSIONAL to clean and set it once you have put in the plugs/air filter.. This will eliminate possible rough idle issues and give the mechanic peace of mind when he is adjusting the carb.
Good luck...

Expedition running rough on acceleration, it's a 5.4L.


running rough means it is misfiring.does it run smoothly without load or at idle?If it does then better check you fuel pressure as the engine needs more fuel under load.

Your cat should last quite a while now it is replaced. I recommend testing coil packs and module. Change plugs and wires and double check your vacuum hoses.

1999 Z24 runs rough when warm


I'd check the throttle position sensor before going anywhere else. Your problem is right in the middle of the rpm range, right where the most wear on the tps happens.(assuming a 2,000 rpm average crusing rpm) An ignition or fuel problem generally shows up first at high rpm's where the load is greatest.
