My neighbor with a 1993 Eurovan is having trouble passing smog, running rich over 24 mph.  The shop she has it at has sold her 4 sensors and is now talking about a computer replacement.  I'd like to find someone in the area who is good with Vanagon/Eurovan fi problems.

Our zip is 90290, Topanga Canyon.  In between the San Fernando Valley and Santa Monica, in California.  Can someone suggest a good shop in these areas...
