Hi – apologies in advance for my lack of some basic knowledge here.

?

Had my 1987 Vanagon converted by Westy Works in El Cajon 1.5 years ago (KEP Kennedy conversion). Working fine until recently when the engine started “stuttering” for lack of better description, while going up a hill. Was able to get it home with only sporadic stuttering. When I slowed to a stop, the yellow engine light came on for a second or two, then back off. I assume an error was thrown. Before trying to diagnose the stuttering, seems best to know if the ECU recorded an issue. However, I don’t have the tools (or knowledge) to diagnose if/what error might have been thrown.

?

So, I’d like to learn the fine art of error code checking.

?

The engine is from, as I understand it, a Subaru Legacy model between 1990 and 1995. So, am I still on OBD I? I am not sure if the ECU was from the original VW engine or if it got replaced with something newer.

?

Can anybody direct me as to how best to determine which if any code was generated? Am more than willing to invest in the right tool(s).

?

Thanks in advance,

?

Terry
