Resetting The Ecu

[richardgrantham]

to reset the ecu on a 1990 g-ltd mr2, do u just disconnect the Battery? and for how long?

please help!!!

[screechmr2]

can just pull out the efi and ecu fuses in the engine bay fuse box, leave them out for about 20 seconds and replace, simply as that. toyota themselves say pull out the efi fuse for about 10-15secs.

my mr2 is running really really rich all of a sudden

do u know if my ecu is a self learning one or not?

any ideas y it might br running so rich all of a sudden?

If you have reset the ECU you will need to give the car time to learn itself again, best bet is to go out for a decent drive with a number of different types of road !!
