Odd ECU Code/

[Sonicfrog]

Now that the MAF has been replaced, Murphy, the $500 87 T-Wag is running really good. Better than it has in quite a while. No more little hiccups or misfires during acceleration. BUT I'm getting a strange ECU code - .4.

 

Yes, it's four quick flashes. Anyone seen something like this?

That is the model designator.

 

1-4 for MPFI

 

excact # specifies manual or auto, cali or federal

 

 

5-8 for SPFI, same deal

 

 

If you are getting that steady, then there are no codes

4 flashes = Automatic California model computer. Pg 105 of the manual I gave you the link too (its for '88 model year though.) The CEL is off right?

No, I swapp'd the crappy 3AT for a FT4WD 5 speed. That one will have to be changed - its leaking fluid and I'd rather have the 5 speed hi lo.

yeah but the computer still thinks it is an automatic. that is what the 4 code designates

I know. After driving Murph for the last couple of days, I can definitely say it has better acceleration, especially low end, than it's had in a very long time.
