Does anyone have experience cleaning the MAF and tightening the air intake bolts. I am having problems with CEL 1128 and have tried everything, cleaning the air box, changed to K&N filter, check the hoses for leak etc. People said I should clean the MAF and tighten the air intake bolts. Anyone know how or can provide guidance?

Changing to a K&N filter is NOT going to make the code go away and if anything it will induce the code since it is an oiled filter. Depending on what year your car is and miles it has yo may just acutally need...........drumroll.............a new MAF!

Remove the MAF and spray with carb cleaner, starter fluid or electronics cleaner. Let it dry and put it back in. Remove negative battery cable for a few minutes to reboot computer and then reconnect. You should be good to go.

I just had to have mine replaced... i still have the old one. It looks brand new. Does anyone know if its possible to test it on the benchtop ?

Since it is so simple to replace, I would clean the old one and put it back in. Chances are that it is fine. You would them have a known good one as a spare which hopefully you will never have to use..

I'm just wondering if most think these types of things are wise to do, or a waste of $$$$$.

New '99 c2 owner here...
Over the weekend I noticed when accelerating hard in any gear... once I got to about 5K rpm the car doesn't continue to accelerate smoothly. It sorta stumbles.
So I tonight I pulled the MAF sensor and cleaned it with carb cleaner. The element was a little dirty but not filthy. After letting it dry, I put it back in.
The car seems a bit smoother but the "stumble" is more consistent. Once I pulled into the garage, the idle fluctuated between 500-1100 rpm....almost stalling but didn't.
So is the MAF toast?

My car chokes in low speed on cold weather starts before I clean the MAF. It was good timing for me to do it two weeks ago because we are in the 20's these few days.

Cleaning the MAF is definitely easy and cheap. I'll do it every year.
The funny thing is that if you do a lot of maintenance you don't feel the car running any better. However, if you don't do it you'll find out little things that worry you from time to time like car not running smooth in cold starts.

Had some free time today so I took out the airbox and cleaned everything, boy does it get dirty. I cleaned out the throttle body, I cleaned the MAF, I cleaned the inside of the airbox, cleaned the outside of the airbox, tightened the throttle body bolts, and cleaned all the tubing. Made sure all the excess oil off the K&N was gone and put everything back together. Started the car, there was a little hesitation then in started, a little rough then quieted down. Purred like a kitten.
Hope this helps with the CEL. I will keep everyone updated.
