Well my old man just bought an 1989 trooper 2.6L 5 speed. Anyway, it's having an idleing problem. It showing a code 12 three times then is showing a code 61 continuously after that. Code 12 is an idle under 200rpm, which is happening. Now code 61 is MAF. I checked the MAF. At idle it's at .95 volts and moves evenly to just over 4v at WOT. This is proper operating as far as I can tell. Is there anything else i can check and how do I get rid of these codes!

did you ever find a solution? i have the same problem.. please let me know
thanks
