I think maybe on this group would have the answer. So the OEM MAF is Bosch PN 0280213002. Mine is disgusting so I looked it up and multiple sites list AF10328 as the appropriate replacement (Rock Auto included). I purchased the Delphi AF10328 stating compatible and I started getting error code 33 which is MAF out of range. Also, the car would intermittently run like garbage. Put the old one back in and it seems fine.
Anyone know if this is the wrong replacement part or where I could find the right MAF to replace 0280213002 ?
After looking around for you, that delphi number is listed for your 85 by several sites, maybe someone with an 85 FSM will chime in but the 14 081 243 # is called oem by most sites. Obviously it is not working. In these days of crap parts sometimes you have to do what you can. I think your option is to try and return it, which many stores do not accept returned electronic parts, or just ask for a replacement explaning that your part works and it does not. There are a few bosch units out there still but you have to look and you have to pay more as well. So the unfortunate fact is it does not work and some sites say it should. Can you clean your old one up ??? If not, you will have to purchase an ebay bosch unit (or from a store that has one) or different brand MAF. You probably already knew that but just needed another opinion, my 2 cents.
Thank you. I'm thinking I may take some measurements before I return it. I'm curious why it would not work. I've also sent an email to Delphi support which I'm guessing will go unanswered. Cleaning the old one is probably a good option since it runs so much better with the old dirty one.
I have an 85 and went through the MAF sensor drama a few years ago... 1985 Corvettes have many one year only parts and the MAF sensor is one of them. Many sites list a MAF that they claim works for 1985-1989 and they do not. I bought one of those Delphi MAF's and it did not work either. The reason is that 1985 Corvettes (and 1985 TPI Camaros and Firebirds) have a MAF Burnoff module (in 1986 they went to a better relay system)). The Delphi MAF is not set up to work with the MAF burnoff module.
The ONLY MAF sensor that will work is GM part#14081243. Blue Streak Electronics rebuilds them (BSE part# MF1243 or 28750). The BSE units are rebuilt GM/Bosch units with the correct part # stamped on them. Catalog | Blue Streak Electronics (bsecorp.com). AC Delco also made the GM MAF (AC Delco part# 213-3373). The AC Delco MAF# 213-3373 is stamped GM# 14081243 as yours is above. Somebody said Cardone rebuilt MAF's but I was never able to find one.
Question though: What is a disgusting MAF? Any codes? Do you have to change the MAF?
My gosh - thank you so much. You already did all the research and have the REAL part numbers. I'll look all those up.
Disgusting just means it is 38 years old and looks really dirty and rusty, but the thing is I didn't get any codes. I just didn't like the inconsistency of the idle so changing the MAF was going to be one of the steps I took to get the best information to the ECU in hopes of a more stable idle. Only the new MAF threw a code (33), but compared to the new one, the idle on the old one isn't nearly as bad as I thought. After all this trouble, maybe I'll just use a MAF cleaner and call it a day.

I was fighting idle issues a few years ago in my 85. There are many things I would look at before the MAF, unless you are getting MAF codes.
I would start with cap, rotor, plugs, wiring, timing.
Has the throttle body bean cleaned (ever)?
I had to replace the IACV because of idle issues.
You also may need to adjust the TPS (Throttle Position Sensor). Checking the TPS is easy. The FSM explains it. If you don't have a FSM, I can post the page for you.
Below is a procedure to set the idle if needed, though in theory you should not have to set the idle.
Of course, if you are getting any codes, address those first.
Here you guys go! Not mine, but I've bought from this seller several times with good results! I even thought about buying it just because, surprised it's still for sale! If I had an '85, I'd snap it up so fast!!! Anyway, one of you guys should buy it, good luck👍 https://www.ebay.com/itm/37489687827...emis&media=SMS

For my 87 I had no luck with the Blue Streak. Car ran horrible. After 2, I wound up finding a used Bosch. Maybe it's different for an 85 but OP should stick with his factory one. Maybe look for a used Bosch.

Did you get a BSE rebuild or a new one? I had success with a BSE rebuild, but I see they make new ones now. I have no experience with the new BSE units.

I am not sure your problem is your MAF, but I dug up some more information on 85-89 MAF Sensors that I want to share.
After some research it appears that the 1985-1989 OEM GM/Bosch MAF sensors are compatible with each other despite the different part numbers. Here are some old threads I dug up on this topic.https://www.corvetteforum.com/forums...n-an-85-a.html https://www.corvetteforum.com/forums...geability.html
1985 is different in that it uses the one year only MAF Burnoff Module, while the 86-89 use relays instead. People in the threads above have tested the MAF sensor interchangeability successfully.
I'm a "Trust But Verify" Person, so I tested my spare MAF Sensor for my 88 (part # 10055877 stamped on it) in my 85 and it worked perfectly for over a week.
This opens up your options and you are not limited to 1985 only for MAF sensors. However, many (including me) have found that "New" Non-GM/Bosch Units do not work well. Buy a rebuilt (or NOS if you get lucky) GM/Bosch unit that is stamped with one of the numbers in the chart above.
