Apparently I need a new computer for my 1974 2.0 with D-jet fuel injection, Fuel Injection running too rich. Anybody know where to find NOS, rebuilt units or know where to send to repair one? Options

Apparently the computer in my 1974 2.0 is not working properly and making the car run rich. Does anybody know where I can find another one or who to go to have mine rebuilt? It's for a 1974 2.0 with D-jet fuel injection.

Also my 3rd cylinder is misfiring. Would this have anything to do with the computer? If not, any idea what may be causing it to misfire? I have a new working AAR valve installed, my MPS works, no bad wiring in the wire harness or spark plug wires, the timing and dwell are on point and the valves are adjusted.

Very similar to an issue I was having with my car about 5 years ago. At the advise that the computer rarely goes bad I chased the head temp sensor and a list of other things before I changed the computer. Mine would flood out when hot. Could take 15 to 30 of drive time and was a little inconsistent but always flooded out even when full open at 45 mph. I would pull the fuel pump fuse and it would start(after cranking) and run out the gas in the cylinder. After letting it cool it would run fine again for a bit. Change the computer it is easy to do in five minutes and there a a fair amount out them out there. It is a lot easier than trying to track down a wiring issue. As these cars get older things that never where an issue are starting to come up. The computer takes a lot of heat and thaw cycles over the course of 40 years.

Please let us know what it ends up being so we can figure out if the computers are starting to be an issue.

Ps. If it is always flooding out remember to change the oil once you figure it out as the oil tends to collect some of the excess fuel and the excess fuel washes the cylinders down.
