here's what chilton service manual says:

95' "w" 4.3 cmfi [email protected] [email protected]
95' "z" 4.3 tbi [email protected] [email protected]

and here's what the designations mean:

mfi- multi port injection
sfi- sequential fuel injection
tbi- thottle body injection
cmfi- central multiport fuel injection
csfi- central sequential fuel injection


please correct me if i'm wrong...

CPI, central port injection. One giant injector in the manifold... Or so I've been told :bash:

Moxon, You probably have the "z" engine. :)
