Aside from old age and vibration, what else can kill a MAF? In the last 6-8 months I've had two go bad and with the prices they're fetching these days I'm very hesitant about putting another one on till I know exactly what could be the cause.

Thanks,

I have not had this happen but I've seen people lose them over oil coming though the turbo. Have you checked for any?

Nope, no oil. Not exactly sure how there would be since the MAF is before the turbo.

Sometimes comes back through due to naughty turbos.

Lousy workmanship on the rebuilds....

Both MAFs have been factory units (not remans). I guess that after 15-16 years they just gave up the ghost.

Banning - I know this is not what happened to you at Atco, but I have been told water will also get in there and screw it up. Driving in extreme rain used to screw up our cars, but like I said, I know this is not what you are chasing. I have a brand new in the box MAF sensor I bought on EBAY, if you want to try it, to see if that is absolutly what is hurting you I will lend it to you. Let me know.

I have always felt that filter oil could cause a problem. Mine (the element)looks clean compared to one that has had a K&N. Every so often, I run an alcohol dipped Q-tip across the element. I did the same with a friends and the Q-tip was oily/grimy...mine was just dusty. And for the past few years I haven't had a screen in the MAF...16 pos ME. I've used the KB type of "dry" filter since the car was new. I actually have two filters, one under the fender and one in the engine compartment.

It has around 140,000 miles with the original MAF. I did have DFI on it (no MAF) for about 25,000 miles.

I took off the bracket early on, so the vibrations are cut to a minimum. I also put an aluminum deflector/shield over the top of it, hoping to keep it a bit cooler. yup

ah, it is time to go then. I have a factory original that was on my gn when I bought it...it started getting screwy and not going to 255 last fall...with the ME, I simply reprogrammed the lock on to a lower number but it is not long for the world, I suspect.

Most originals have long since bit the dust.

Not to get off topic but, my MAF dropped from 255 when I took the last screen out. I think it has to do with the velocity/direction/pressure silly of air passing the element. With the ME I just locked it on at 237. headbang

Thanks for the input guys. Never thought about the air filer oil being a possible cause. I *lightly* oil my filters, so I don't really think that's it though. I'm betting that they're just old and their time had come.

Can't wait to go MAFless. I've got my ECM & thumbwheel all boxed up and ready to send out!
