I think you have the wrong sensors. Bosch 13942 is what a '90 and '91 Gen 1 car
uses. I originally got a different part number for a friend's '91, which was
indicated to be correct by my NAPA dealer. The same conditions occurred for me
as
are occuring for you. I got this number, which was theoretically for a '92 per
NAPA, I think, and they work correctly. The differences are dictated by the
various
PCMs (computers).
Someone on the list here knows what sensors to get. The books are wrong at many
auto parts stores.
I don't know about Gen 2 specifics, or I'd be glad to tell you which ones to
get.
