Hey Guys.. I am absolutely stumped on an issue I'm having with my truck.
My truck is a 1994 F150 with 4.9L Straight 6 and a 5 speed manual transmission.
The problem is the truck is running extremely rough. Like it's missing. It also uses a lot of gas. but it doesn't smoke or anything. I have been 57.8 miles and i have an eight of a tank left.

I have checked for spark to all cylinders its all good.
These are the parts i have replaced
PCM
ICM
TPS
CTS
EGR Valve
EGR Valve solenoid
Fuel Pump
Fuel Filter
Spark Plugs ( twice )
Spark Plug Wires
Distributor Cap
Rotor Button

I'm Probably missing a few things but the MAP sensor checked out good. O2 Sensor checks out good. When i run the OBD1 code reader on it i get 111 which is system pass when the key is on and engine is of. When the engine is running i get code 213 which is spout circuit open. I've set the timing. (with the SPOUT out) I've traced all the wires and their continuity and it all checks out good i can't find a bad ground. I have no idea what to look for or what to do any more. can anybody help me out ?
