Need help diagnosing,
65 mustang 200 ci with a Carter YFA from a granada 250. Electronic ignition (ford factory DSII). Stock coil.
I have been driving with this setup for two years with no problems, Last night coming home I had a loss of power and heard a little more hissing sound coming from the carb.
The car seems to be only able to rev to about 4000 and then back to idle it is rough. Playing with the accelerator a bit and it will idle ok but once you gas it it will go back to rough.
Plugs were a bit fouled due to me flooding it in this cold weather, and number 5 had some crusty crap on the plug.
What I've done so far-
Was running a little rich- reset float (brass), changed plugs and checked dist. cap and rotor (no change).
Checked fuel filter (fine) checked oil and water for contamination (none)
Checked for vac. leaks and (found none) Pcv seems fine.
Checked timing (good)
I'm down to trying to figure out if this is fuel or ignition. If its fuel then maybe the carb?, coil or Ign. box? Head gasket?
Anyone experience these symptoms? Any help would be appreciated.
This car is a daily driver.
Thanks, Mike
