My son has decided to get a truck similar to mine, but we want to stay pre-computer. In what model year did the computer appear?
Thanks in advance for any help you can provide.

'81 Flareside
300/6
4 spd
3.31 gears
33"/31" tires

 

It depends on the engine , For the 300 cu in engines 1987 was the first yr Efi was used . For the V8 's I believe 1985 was the first yr for Efi .

 

Wasn't there a period where the trucks came with a computer controlled carb? If so, when was that?

85 and 86 F150's with the 300 I6 had computer controlled carbs, worked great when new/newly rebuilt but all it takes is a little fine dirt in the gas to screw them up and then they're worse then a poor conventional carb.

I've seen several trucks with the EECIV and a single barrel carb. Looks like quite a pain to deal with tuning.
302 was 1985.
351 was 1988 as was 460.

 

I drive a 1984 F 150 300 w/computer. Now anybody know where the oxygen sensor should be and what wire it hooks to?

 

the O2 Sensor goes into the Exhaust pipe and has a single white wire that hooks to it I have a 84 also with a 300 1 barell feedback carb what they are called it isbnt bad I get about 13 with mine a lot better then a quadrajet by Rochester

 

 

1984 was the first year Ford put EEC-IV in its vehicles. I'm not sure if any other engines besides the 300 had feedback carbs?

 

I know my 83 F150 had the Duraspark 3. Is that the equivalent to the EECIII?
