Default Maf replacement and still runs cruddy

I've changed the mad to the new one after installing a CAI and now for some reason it runs worse than before. I can't accelerate for hardly ****. Did I do something wrong? I know some cars new to re-learn or need the computer to reset so the maf reads right. Is that the case here? You guys have always been helpful with everything here, I'm hoping to get this fixed asap! Help!

Define "new one"
Did a "new one" come with the CAI ?
You should always use the original MAF when you install a NW CAI on an NA.

maxchicon and I installed my single CAI ( second hand, got it from a guy in San Diego ) at his home in Auburn, I immediately drove home ( 70 miles ) and had no issues at all.
That was 4 years ago, no issues since.

Did you install a new MAF sensor, new MAF sensor body or both.
You need OLD sensor if you installed a new 74mm MAF body and CAI, or just the CAI.

I probably should've clarified a little bit more sorry guys, soooo basically I have had a maf code for awhile and I figured it had something to do with the way the stock intake sat on the maf sensor so I went ahead and basically made my own intake with dual filters run behind the grill. I work at an aluminum plant so I just welded my own up.
I bought a maf off eBay awhile back and tried to install it and the car ran worse than before, so I figuredit was either a bad eBay part or im not doing something right? I tried unplugging both terminals for well over an hour and checked the connections with the plug when I plugged it back in. I know some cara need to relearn a new maf sensor. I'm at a loss honestly. It'll drive but studders hard at 30 to the point I should pull over. I've also checked vacuum leaks and everything seems okay. I'm not stranger to turning Wrench's but this is baffling as hell😬

I installed the body with the sensor inside it. Where can I get the 74mm maf body?? I've heard of doing this mod but I can't seem to find anyone with one

Turn key to on position (do not start), press gas pedal to the floor( hold for 5 seconds). Turn key to off position, then release pedal. Do not remove key, for 2 minutes. Procedure complete.

Back up and try your original MAF. Then one step at a time. I think we are all confused.

I connected the original maf and it still runs the same, so I unplugged it while the car was idling and it didn't change how it ran so it has to be a bad maf. Its possible that the one off eBay is a dud right? I mean I spent like 30$ on it so I'll take the bite out of my wallet and buy a boshe if need be. So I don't need to have a computer reset my computer in my car or anything, (when I get a new one) it should just be plug and play correct?

When you are talking about the MAF are you meaning the plastic elbow pipe or the MAF sensor that screws into the plastic pipe OR both? If you replaced the plastic pipe then you may have a problem with it seating properly. If we are just talking about the Sensor that screws into the MAF a new Bosch may cure the problem BUT, If the car is idling that bad you should have a trouble code. Have you read DTCs ?? Go to any auto parts store and ask them to read the trouble codes BEFORE you buy any new parts.

I replaced the maf and its housing piece that it comes in. When I had the car scanned previously the only code that came up was the maf malfunction. I checked all the seals and it is seated properly. Perhaps I should buy the name brand like boshe and I'll have better luck

I cannot follow this at all, I get mixed up with the MAF and MAF housing. I think I would be tempted to start out with the original parts on the car, see what code is set and go from there.
In other words find out the basic problem before trying to solve it by adding other parts that may compound the problem.
We expect you still are using the original MAF sensor it may only ha needed cleaning and you may have replaced it with a broken one. Who knows, get back to square one and start again.

I read this tread for 5 times and I guess you bought a new MAF from eBay and not a Bosh so in fact a generic thing which won't work. You want to use either a 68mm MAF + Throttle = stock from Bosh or do the 74mm mod = MAF housing + Throttle body from Bosh.

Moreover I read that your original MAF isn't working properly so
1 you need a new MAF with Sensor from Bosh
2 don't buy generic MAF/Sensor
3 keep it 68mm stock or do the 74mm throttle + MAF mod from BOSH only ( used works too )
4 onve you installed the new MAF either 68 or 74 do a throttle reset, it didn't work for me so I just unplugged the negative batterie for a hour and then it worked.
5 any questions ?

Sorry about the confusion guys but Yeah basically I believe my original maf went bad, i figured that the ebay part was too good to be true. Can you direct me via a link to the maf mod? If I'm going to replace something I might as well improve it. How do I go about ordering the 74mm parts? Do you have a link?
Thanks for the help guys at least I know where to start now!

I've found a few parts via googling them but none of them are boshe. So instead where can I find the original maf sensor? The only boshe maf I've found so far is 250$....
