Hey all,

I love this site and it has helped me with my 1994 Non-Turbo Auto 850. Until now haha. I have found so much on here about the MAF but have the following issue I though someone may be able to help me with.

My car was running well, however, after reading about others cleaning the MAF I decided to give it a try. I took mine out and used CRC on it. I also purchased a new air filter element, cleaned out the filter box, air inlet tubes and flame trap. I then put it all back together except the MAF. Whilst I was doing this my 6 year old son grabbed the MAF to ask what it was and at the same time broke the internal sensors with his fingers!

I went to a dismantlers and acquired a spare one but when I put it in, the engine started running rough, and the "check engine" came on with the 121 fault.

Thinking it was a faulting MAF I acquired I cautiously drove back down to the dismantlers and tried 3 other MAF sensors. Clearing the codes between each, they all resulted in running rough and stalling as well as teh dreaded "Check Engine" light and code 121. (I therefore, after 3 different MAF sensors, do not believe this is the problem.

I drove back home and just now retraced my steps to make sure I reinstalled everything correctly. Same issues continue!

Wondering if anyone has any ideas?

Were any of the junkyard MAFs off a 94?

I am also inclined to think the same way. You probably purchase a different spec-ed MAF. I think there is a difference between a Turbo versus an NA MAF.

But in anycase, and that worry put forth, you dont know how long the other MAFs have stayed on top of the shelf, collecting dust all the while. You may want to clean them a bit before testing them.

Dont worry about the son thing, it has happened to many of us. Frankly, i would be happy if my son is half as intrigued with the car than not. At present, his 4 year old mind is still TOO much on Astro and Ultraman and all those stuff. Hmmm...

Hey,

I have been doing some searching and whilst I knew there was a difference between a turbo and non-turbo MAF, it also appears that there is a difference between a non-turbo 93-94 MAF and 95 onward. I will need to research that more. Different parts sites seem to be giving conflicted information.

Look at the part number, as long as they are similar, they should be OK.
