I was wondering what would happen if i plug in a PR4 in to my 90HB. it still has the stock motor, will it still run?

 

nope as u have a motor set up for only two injector and the crank angle senor and positioning senor different then a MPFI engine


so it might not work but if it does will run like ****

and check engine light will be like a disco

maybe not that bad but won't work
will run horibble or not even to the gas station

 

LOL... dam good thing i didnt try it... that woulda been funny. I didnt think it would even start up. but i figured if it did i would have a higher RPM limit... lol..

 

but if u change the clinder sensor wires around, would it run?

 

if you convert to mpfi it might run with a cel

 

Why would it run with a CEL? If he did the MPFI properly I don't see why on OBD-O PR4 wouldn't run and not throw a CEL. It would run rich, and run like crap, but that's another story after all.

 

well i was just wondering... my babys mom has a Teg & i was getting board & thought about doing to see what would happen. but good thing i didnt.
