Welcome back, Wayne... Good to hear your car is doing good..mostly.. Mine's been ok, cept I've got a few little problems I can't figure out...just installed a new TPS and it didn't do a d*mned thing except that the car ran really rough and had terrible low-end power with the ECM reset. Argh. Wish I could tell ya about the MAF to MAP conversion but I can't...I thinkt he MAP has a vacuum line that runs from the plenum to the sensor..I'm not sure if the MAF car plenums have that same hole for you to route one. Also I don't know if the computer is programmed to accept MAP data...but I'd think it doesn't have the thing programmed into it. But hey, ya never know.. I'd start shopping somewhere else for the MAF! Or give Advance a hell of a time about it....

Hey Wayne, what's up? School's kickin' me too, just took a midterm yesterday that -nobody- finished on time. (Except for 2 people, and I glared at them) Everyone was complaining about it, so there'd better be a hell of a curve on it, or I'm going to chew someone out! Professor didn't even show up for the midterm, he had his teaching assistants give it to us... I never had that happen before. The professors I've had always made at -least- an appearance.

GM had a TSB out about the MAF-MAP conversion. People were getting ticked about always having to replace the MAF, so GM came up with a procedure to convert the car over. My dad's old '87 Oldsmobile cutlass ciera 2.8 had that conversion done. On those Gen II 2.8's, the MAT sensor is built into the MAF. So from what I saw, the conversion was a simple one. The MAF relay was unhooked, leaving the harness to the 5-pin MAF, 2 pins of which were the air temp sensor. Wires were patched into the MAF relay wires, and they ran over to the passenger side of the car. The MAP was bolted to the passenger side cowl lip, and a vaccuum line went from the MAP to somewhere on the motor (can't remember). A silver sticker on the front driver's side strut tower said something like "warning, computer chip changed as part of service bulletin #something, please refer to service bulletin for details".

This conversion happened mainly on the Gen II MPFI 2.8's, but I don't see why it couldn't be applied to our Gen I's. Maybe we don't even have to change the computer, just the chip!! Maybe you could call GM about it.

Oh and you didn't have to pay for all 3 of those, did ya?? If so, ouch, a new GM one is about $300.

I had midterms this week also Tom ! I was sooo ticked off !!! My proffessor graded my photography test in front of me , I read one of the questions wrong so therefore I answered it wrong . I then told him the right answer but he still did not give it to me ! I made a "C" on the exam, but if I would have read that question right , I would have made a "B" on it ! O-well !

Thanx for all the info Tom on the Maf-Map .
No , I have not been paying for these maf sensors . THANK G0 D ! heh . They have been under warranty . Im just sick of going through this miss . I know its prabably one of the easiest things to change on a car , but I dont have a lot of time to keep messing with it !

Yeah , I had a new tps put on not to long ago to . I was wondering maybe this time , if its not a bad tps , but I think its the maf sensor againn . Im ganna test it with my tester again to make sure . .....Man Tom , I've flat used that MAF sensor tester that you told me to get ! .It also test MAP , so I can use it on that if I convert over !

That's the #1 thing I'm looking forward to when i graduate- I don't mind going to class, I almost don't mind homework- but I hate being tested. Knowing that I'll never have to take another damned test again is what keeps me going!

Are you testing it with the multimeter or that $10 Sensor Tester?

That sensor tester .....What's funny is , after I get a new Maf , it works fine for about 2 weeks , then starts acting up and gets worse and worse , then I get sick of it and go exchange it for another one , that one last for 2 or 3 weeks , until it starts going bad again .It's wierd

Yeah , I hate taking test to !!! I can study and know everything and go make a "C" on a test sometimes because I get nervous .

Is there something in the car that could be making the MAF short out? Is the filament or anything like that damaged when you bring them back Wayne? Maybe the computer is frying the MAF circuitry somehow..?

Hmm...taking shots in the dark here....are there any problems with your electrical system that you know about? Power surges in particular? I wonder how sensitive MAF circuitry is...I know certain circuits can be fried by excessive radio waves and stuff, and I'm pretty sure our cars generate radio waves...that's why people buy radio suppression cored plug wires... Maybe it's just a junky MAF design....although I still find that hard to believe... I'd get your money back first, and run a different MAF sensor from some other store...if that shorts out too, then I think that's proof enough that it's not just a bad line of sensors, that it's something in your car that's frying them...

but the problem is , Advance wont give me my money back , I tried that the second time , to get my money back . I was thinking I might try it one more time , like you said , with another one and if that does not work , i will have to do something , look into having electrical problems or try to get a decent maf ..Thanx for all the help Nixon .
