Has anyone had any issues with aftermarket maf sensors? I have a 1987 Iroc Z 305 tpi. The Bosch maf sensor died. I picked up a new one at Oreillys. Its a Spectra anyhow I got a trouble code within an hour for the maf. The wiring to the maf is good. What are the odds of gettinf a bad maf sensor out of the box? Should I go with a Delphi or AC Delco? I saw th AC Delco is 739 bucks at autozone is that a misprint? The Delpi is 140. Any suggestions? Thanks.

Is that a new maf or rebuilt?

Im not sure the light came on as I was diving it to the shop for some transmission work. I can ask them when I pick it up. They suggested a GM maf.

I may just try the Delphi. I dont know why this one doesnt seem to work properly? I am definitly returning it. The Delphi is a OEM the Spectra is not.

Last I checked, the Spectra Premium MAF is the same as the Wells MAF that was popular here a few years back. It's not a hot-wire type like stock, and not remanned.

So this is good then?

I just read a couple Amazon reviews on the Spectra I bought one was bad right out of the box and the other was throwing codes right away. I will return it and go with a Delphi.

myzticc66

It was a new one by the way not remanned.

It's probably junk. Years ago I bought several that were defective right out of the box. I think I eventually went with a Bosch one. I have had so much bad experience with Spectra products that now I won't touch anything with their name on it. Same with Dorman.

Yes a GM mechanic said the same thing. I ordered a Delphi

I had trouble with a Bosch OEM-style hot wire one and have been running the Spectra for about a year now without trouble.

Nice. The one I got has a circuit board in it that is not programmed correctly. The one Im replacing is Bosch. Has been in the car over 20 years and just died. Not a bad run

I had issues with replacing a MAF years ago (1992) in my 87 L98 that I had back then. Went through 2 MAFs from TPIS before a mechanic found a faulty MAF relay. Problem solved after replacing the relay. I cant remember where the relay is located though. To many years and beers in between. Worth investigating though before spending more $$

Also, I don't remember the brand that TPIS offered.

I had mine in for transmission work. I had them check it out they said the wiring and relay are good. They figure its either incompatable or just bad. I ordered a Delphi which is a oem. I noticed the Spectra is not. It a so called direct fit. Now I have to get Oreillys to refund the money. They say if it was installed they give you another one but could refund it. Im sure they will refund it. Im in there enough.

IIRC, the MAF relay is on the firewall, right next to the power brake booster//

I bought MAF relays for my 88 at Rockauto.

If you were crafty, you could make a solid state relay for the burnoff using a p-channel power mosfet.

Got everything working. Just can't get the trouble code to go away. Car is stored now till May.

Ok, I forgot to answer all this awhile back. I got the problem solved. No more trouble code is gone. As stupid as this sounds The answer was putting the original Bosch MAF back in. I was told by 2 shops that it was dead! Well it was not dead. It works great! I never bring my car to a shop. I had originally brought it there to have them do a scan and their answer was the MAF was dead. They were wrong. Still do not know why the Spectra or the Delphi don't work in the car? Happy the old Bosch is still kickin!
