Mass air flow sensor and other questions (long post) 200 1983-1984

I just bought an 1983-1984 240 GL last week. While doing a tune-up on the car I managed to break the neck off of the radiator causing a nice 150-degree shower for me and the car. (Ouch!) Anyhow, I have repaired the radiator and have new problems as a result of the shower. It seems as if the coolant got into my air-box and soaked my filter and maybe got to the mass air flow sensor (AMM in volvo). So since I had my open element filter handy; I installed it rather than replace the paper filter and clean the air-box. (Figure that I had to use it somewhere, why not the 240?) Anyhow, I drove the car for a few days and all was perfect. Then the car began to act as if it were out of fuel. I looked over the car and found nothing obvious. So I cleaned the AMM with Berkable brand Gum Cutter. Car ran good for another day. (Figure since the Open element filter was sitting in my storage for a while some dust may have gotten in there and hence onto the AMM strand.) Well, here I am a few day later on...I have had no choice but to un-plug the AMM to get the car to run at all. I have re-installed the factory air-box and am in search of a replacement AMM. I guess it really did not like my K&N open element filter too much! Would it be safe to assume that my sensor is toast? The car will run very strange w/out the sensor connected. With the sensor connected it will only run at wide-open-throttle. And at WOT it will only pull to about 3K RPM in a sick way. Acting like no fuel once again. Strange part is that with the sensor connected and the engine trying to maintain RMP, the car will run great for a second after a back-fire. So anyhow I'm not too sure where to go from here. I have access to a donor car which is a 1987 or newer 240. I have not looked at the AMM in that car to see if it is the same or not. Just wondering if anyone knew if all 240 series AMM's are compatiable or not. Also, will I stand to gain anything from a different type of AMM? I would like to keep the Open filter but I have heard some talk about the can kill the AMM. (Heard this after the fact, of course...) Also, any other suggestions about ways to get around without the AMM. (Tight budget.)

Thanks in advance. Oh, and sorry about the long post.
