Are the MAF burn-off and power relays the same part numbers for both, or are they completely different from each other? (I obviously haven't yanked the battery yet). The local NAPA store shows one part number for the MAF relay, as does Ecklers. Just wondering if they are interchangeable.

Thanks!

I changed my MAF burn-off realy and I used whatever NAPA gave me. I think they are interchangeable as both relays look the same.

Thanks!

Your should be the same as my 87 and yes, they are the same PN and are interchange, can swap for testing... if they rattle inside, they're bad... but at $11 each at napa, i just replace them both

This TSB may be superseded but if still valid, the '86 used different relays. I've replaced mine with the two different part numbers called out in the TSB. YMMV as I've heard many '86 owners using the same for both.
TSB 87-270

On my 89 both of those and the fuel pump relay are the same.

My 89 are all the same part number.replaced them all from dealer parts department. Not an expensive item. If I remember correctly they were only like 11 bucks each.

It was a long time ago so.....IIRC:
I think the original relays were different PN. When I replaced the MAF relay I then got another MIL (trouble code) for the Burn Off relay . When I talked to my GM parts guy he chuckled 'cause he remembered the TSB. With the replacement relay you had to change both MAF and burnoff to the "new" common PN or code gets thrown.

Like I said, the TSB could be superseded. As I recall (and I'm the original owner of my '86), both relays were the same 10067925 part number from the factory. When replacing all the relays in '96, I remembered the TSB and went with the part numbers from the TSB. Interestingly, the parts book that runs through 1996 lists both as 10067925 even though the TSB was issued in 1987. I'm pretty sure they were both 10067925 from the factory though as I keep all the original parts and my engine parts box has two 10067925 relays. In the end not a big deal though, I guess. Use what works!
