4.9 engine barely runs
Hi
I have an 84 F-150 with 4.9 motor. Was driving down the road and all of a sudden just started running VERY rough. At an idle it jumps, sputters and stalls. Changed distributer cap,rotor,MAP sensor,pcv valve,fuel filter and plugs. Plugs have the dry sooty look. Carb. is about a year old, don't know for certain but it appears to be ok. Ignition module ohms out good according to Haynes manual. Have a used spare(in case I get stranded again) and swapped that and no change. Any suggestions appreciated.
Thanks
