Misfire

[supraguy]

I have a 1987 5-speed turbo. And bought this car with the misfire thinking I could fix it, but I was wrong. I have changed all of the spark plugs and cleaned up the throttle body. But there's no change. I tried spraying water on the wires to expose any cracks, no luck! I sprayed brake cleaner over every gasket and hose, no luck! I dont have a check engine light on but I do have some codes 24 (intake air temp), 31 (air flow meter). Any thoughts? Any help will be appreciated. thanks
