I tried taking my screens out. Using the MAF from my husbands old engine. (same year as mine & from the same car 87 Irocz)
& all we got was the car starting fine then shutting down like it ran out of gas.
Coded it & it came up with an odd reading. I put mine back on & it worked great. We did this 3 times. all the same results.
We took the MAF in & had it tested & it was still good.
So I am NEVER going to take the MAF off my car again.

 

Perhaps the answer should be to descreen it and reprogram the ECM for optimum performance and all will be well?

 

I never said that, did I? What I'm referring to as being unintelligent comments is those that say that removing the screens will HARM your engine, as that is not at all the case.

If you choose not to remove the screens, that's your choice, that's just fine. Doesn't mean you lack intelligence. BUT...to say that doing so will cause harm to your engine or will decrease performance is unintelligent.

And...not plugging your MAF back in will cause it to run like you described krazycowgirl. Removing the screens has absolutly nothing to do with the sensor at all, meaning that removing it will not cause it to go bad.

The ONLY code I have EVER gotten from my MAF was for the MAF burnoff code, and I'm convinced it was from recharging my K&N filters and there was just an enourmous amount of oil left in them and it just happened to get stuck on the MAF, that was WITH the screens on, also, the guy who went on about the GM manual, you do know GM has lied in the past, right, such things as a 290HP rated z28 in the late 60s, that was really rated somewhere around oh 390HP, just because GM doesn't say it, doesn't mean it isn't true, why don't you go ask john moss how he feels about MAF screens, I bet he'll tel you to cut them out.

 

Lungz, I'm well aware of false horsepower "ratings" on the First Generation Camaro's with a 302 cid engine. General Motors never actually released dyno results. So all the figures you seem to know are false. Some speculate that "most, if not all put out more than 290 HP and 290 torque at 4800 RPM's". GM never intended for the public to buy the car, so they had no reason to apply an exact figure to the "breather sticker". The Z-28 was basically intended solely for the SCCA Trans-Am race to compete against the Mustang and Barracuda. Near all of the first 1967 Z-28's went to either race teams or certain dealerships, I assume for display.

Now that we got that small history lesson over with... can you tell me of another instance where proof has been brought forth showing where GM "lied" about their automobiles to deceive the public?

and BTW... who's John Moss? lol.

 

A I can tell you I have worked for GM dealerships for over 20 years. Everything from line tech to service manager. I have been to the tech center several times to help them straighten out some screw ups the Generals Enginers have done. Go to any dealership and look at the repair manuals and see were GM will send out update because they were wrong. I have fixed many problems that GM screwed up. That is why there are recalls. And yes they have lied at times. Think back to the people burning up in trucks with the gas tank on the outside of the frame rails. GM stance was it was cheaper to pay the law suits than to do a recall on millions of trucks. Ford did the same thing with the fuel tanks behind the drivers seat. There are many other things I can tell you about all the car companys as I have worked for a few. The dollar is first and for most in there mind. i have had to show why my warranty expense was out of line. I knew there was problems with customers cars and would fix them before they got stranded. The DSM from GM would come out and say don't fix that the car may go out of warranty before we have to pay for it. Them knowing every car that came down the lines was more than likly going to fail before the customer got out of warranty. We were one of the #1 dealership in the nation for customer coming back and buying a second or third car because we took care of them. I just want to say that all car companys about the same when it comes to the dollar. Don't think that theyare not.
