ok this might be an easy one for you guys, but im bored. ok so i put some mpfi into my 85 carbureted wagon. i took most of the stock stuff out of the engine compartment that i wouldn need for the efi system im runing, no more canister, ac, power steering, did away with alot of stuff.

got it installed, got it all wired up, hooked up the one vac line that goes from teh car to the engine to give my heater controlls vaccume.

i start the car and it starts great, then procedes to rev to the moon. i shut her down look at throttle linkages, vac lines in the way, that could have hung it up, nothing. try again and it goes to the moon again. at this point im thinking all kinds of stuff... after checking a few lines i figured out my problem.

can you tell me what i did to make my car do this?

Big vaccum leak maybe.

im talkin pedal to the floor reving.

sounds like what happened when I swapped in the ea82 manifold and carb, the cable "looks good", but was NOT seated, or the bracket was wrong for the application

 

 

is the engine you put in fi or carb

 

is it audibe rev or tach rev?

wrong vacuum line..........

Unruly truck monkey?

the little rubber boot on the sheath of the throttle cable came loose and wedged itself into the groove on the throtle bracket itself, keeping it from returning

pedal was fine, untill it started, then it went to the floor.

Accel cable for the carb one still on and the length isnt right for FI?

is this vehicle equiped with cruise control? if so then you had the wrong vac line hooked up to it so it would suck on that lil diaphram that controls the accelerator pedal and so it would rev to infinity and beyond

that was it, i had no idea it actualy moved the stinkin throttle pedal, i thought it only messed with something on the carb. i damn near blew the car up wish i had been looking at the rpms. the heater controll vac hose comes out right next to the cruise one.

you win brat rear bump stop(well used)!

 

i trimmed the cable earlier, so it has more throw.

aaahhheeeeemmmmmm.......i believe that is what i said....wrong vacuum line.

brian, isn't it past your bedtime?

yeah but I nailed it right on the head hahaha hmmmm now what to do with that well used bumpstop.......... BURN IT muahahahahahahaha

damn, i needed that bumper stop yeah yeah, you were right......did ya just need to hear it?i just kinda figured it was a vacuum thingy.....good job nut
