[Adrians89MR2SC]

blew the dust of my old 89 mr2 sc and tried to get it running .. put a brand new motor in it this time last year and haven't started it yet (well hasnt run yet)


it will start, idle really rough, then cut off after about 10 seconds

got a guy helping me right now trouble shoot it, but were runnin into some trouble


cleaned out the throttle body and ISC - didnt fix it
checked all my grounds - there good
checked timing - timing belt and distributor are right on the marks
afm - checks out good

printed off all the pages for troubleshooting the EFI system with a multimeter

only thing ive come across is when I was checking stuff with a multimeter on the ecu w/ the ignition on is the voltage for the AFM wasnt in spec for vs - e2

its supposed to be 3.7 - 4.3 volts .. but im getting about 1.5 volts when the afm plate is closed

the motor idles really rough, smells rich, and the plugs are black when I pull them

the AFM ohm's out good according to the BGB, and the wires from the afm to the ecu are good (no shorts or corrosion)

would a bad ECU cause this to happen? .. there is some rust on the ecu like its been exposed to water or something

that guy has two good ecu's, so tommorow im going to get one and try it ..

anyone got any other ideas of what might be wrong?

thanks,

Adrian
