Start with the O2 sensor and circuit. Make sure the ignition timing is
not over advanced.

Subject: 87 Vanagon Emission failure -No Va

My van had been sitting most of the winter -took it out for an emission
test and it failed. The mechanic thought it might be to much fuel being
dumped to the injectors and the fuel regulator may be bad.  Here are the
readings     15 mph    limit    Result

                                                                    HC
