Code 36 MAF unit. have ?'s step inside!

[Heavy Duty]

HI JACK A THREAD!! Even the part numbers for excel relay's from NAPA.
Mike and I just got threw replacing that junk.
Everything you need to know is in this thread.





The factory manuel always recomend the relays be replaced when a code 36 is thrown.
It's is a service item that chevy recomends.
If you are cutting and splicing wires it builds resistance and could, but not likely put a load on the ECM.
You should also know the 1986 corvette has the worst wiring of all the vetts.
Something with the coating not to mention putting the wires next to the EGR tube which gets about 900 degrees,where the main harness goes through the fire wall.
NICE MOVE CHEVROLET!!

If anyone needs the factory break down sheet for code 36 another member sent it to me ,let me know.

Redc4,
thanks for the info. I would like to get a copy of the code 36 sheet. I think that would be a good starting point in trying to figure out why mine keeps eating MAFs and ECMs. I think that should be my next move before i go investing over $300.00 in parts again. I still think that the re-splicing of the wires is a major contributorto this problem. Computers are very finicky when it comes to screwing with the wiring. Voltage and resistance have to be within specs or things go south in a hurry. I learned that when i was working on aircraft. Looks like the same rules will apply to automotive computers. How hard is it to replace that wiring harness? Does anyone make a complete wiring harness for the ECM and all of its sensors? If not i guess the next move would be to put the harness on a peg board and make one.

Thanks.

Thanks Mad-Mic. I saved it to my favorite sites for later. At the rate this thing is going through MAFs and ECMs I may need to make the move and R&R the wiring harness. I told the guys last night to not do anything to it just to go ahead and finish the paint and such. I'll take it home and do the trouble shooting myself.
