1G Trouble shoot assistance needed

[Alpha D]

Ok. So i need to check the ECU itself. I can inspect it for leaky capacitors. I do not have a logger though. The car does not have a safc, dsm, link, or wideband. Regarding the MAS i do not have a second one to replace it with.

-How can i check for a bad wiring job?

-Should I take the Computer into elite, or map for inspection?

-I do not want to let the car idle for to long yet drive it. So should i take the MAS with me when i take it in to get inspected?
