Ok. I picked up an 88 runner sr5 3.0 with bad head gasket. i got another 3.0 from a friend who was parting out his 91 pickup. the engine has high miles but ran fine in his truck. I swaped this engine into my truck and it runs,kind of. it will start but it it runs very rough. it almost dies when i put the auto in gear and has even less power than a normal high milage 3.0. i checked the timing, checked for vacum leaks and i don't have any codes. what do you guys think the problem could be? thanks in advance for the help

 

Did you check all your ground straps?

 

Injectors . Use the injectors from the 88 . The 88 has a different impedence from the rest of the 3.0 s

 

Thanks guys i did check all the grounds and I had to use the 88 injectors because the plugs are different i am now thinking mabey i have a vacum line hooked up wrong and the egr is staying open or mabey i have an injector that is sticking open. what do you think? oh and did i mention this this thing is a major P.I.T.A to work on. I swaped out my 22r in my last truck in about half a day by myself. this one took all weekend with another mechanic helping me one of the days.

 

do you have the air intake hooked up to the afm?

 

I'm not sure what that is but I probably have it hooked up

 

afm= Air Flow Meter

 

Yea i got that hooked up. it wont run at all withuot that will it? any way I disconected the egr and pluged the hole and it pretty much run the same. any other clues?

 

Hey come on guy's I have an sas kit sitting in the garage that i'm dieing to put on but can't bring myself to do it until i get it running right. please help
