Topic: need some quick help

[83yota]

ok i have an 85 runner that i blew up the engine. i picked up a good engine from an 88 truck. i put the engine in and it starts GREAT. but as soon as i hit the gas it dies out. i was told the comps are different. is this true? could this be affecting the problem. i tried the timing... good... good fuel, filter new, plugs and wires new. what else could be the issue? i want to start driving it again. if this is the problem can i just switch the comps and get it to work.

anyone??? i REALLY want to start driving this thing again

Maybe do a quick comparison and see if you are using all the same connectors for the electronics.. make sure they are all being used and hooked up with no extras.. I would start there..

it is all the same except for 1 smog sensor that was on the 88 not the 85. thank you for the help. PLEASE keep it coming.

really no one has had any issues like this before?

[chim]

Have you tried switching computers like you already mentioned?

sounds like a bad air flow meter AFM.

[83yota [OP]]

is that the one in the air box? i will try to comp next

[boggerunner]

yep, its the aluminum pile of crap on top of the air box.

[83yota [OP]]

do they "just go bad" it worked fine before i put the new engine in.
