1991 sidekick JX 8V Manifold glowing updates!!

[Dirtybeerguy]

With the Help of some members , Im a little closer to diagnosing my trouble. In my last post I told you guys my manifold is Red Hot Glowing, engine missing at hot and cold, Loss of power, etc. I also stated that previous owner had taken CEL ( check engine light) out. OK, UPDATE----- I replaced CEL light, pulled dome fuse for 2 minutes to clear all codes, turned key on, but NO START---CEL flashed 12-----Good News KINDA!!!! Now, I started vehicle CEL light came on and stayed on steady. I then shut engine off, hooked up my jumper wire to diagnose a code, again turnd key on(NO START) and I now got a flash,flash, flash,..PAUSE.... Flash !!!! I take this as code 31. I crossed referenced to Haynes Manual and it says CODE 31 is MAP Sensor. Now, I need you guys to Help. I cant seem to find a cheap one of these things anywhere. Another thing, Do you guys think this could be my problem? Anyone got this part and want to sell it? Can I clean it? Can I check it with an multimeter? I hate to buy it and it not fix a thing--If I had a lot of money I wouldn't be driving a Suzuki Sidekick now would I???? So, If anybody has any clues what to do next ( Rather than jump off a Cliff--Reply PLEASE) Just joking on jumpin off the cliff, I meant Building!!! HAHAHAHA Smile you guys, I would never do anything like that---My Wife would get the insurance money and be HAPPY!!!! Getting back to business--Thanks but shoot me those thoughts I gotta get this Baby running. It just kills me to see my baby in the yard S-I-C-K and Broke down!!!!
