F-150 Question???

[apex827]

I know its not a stang, but its a ford, so i figure someone on here would know. What year did the F-150 switch to the R-134A system and when did it switch to mass air?

Thanks

The switch to r134 was around 1993/1994 in Fords. Different models went different years depending on when there was an update or refresh.

well i know they refreshed the f150 in 93. wasnt sure if it switched to r134, thanks.

any idea when it switched to MAF instead of speed density? im pretty sure my dads 88 bronco had MAF but not sure if it originally came with it or if he did it and if it was the same for the f150.

maf was 95 in cali trucks, 96 in the rest. this includes broncos and e-series vans. easy way to tell if its been converted is the s.d. trucks will have two intake tubes going to the air box, while maf will have a single that will y off into the dual tb.
