Ingo! do you have specific voltage test results at the fuel pump(don't
forget the ground side), 15 at the ECM? over 12 v.and the coil, voltage drop
though the intake air temp sensor, if so post 'em, and O2 sensor range
voltage, from . minimum what to .maximum what. I assume you do not have a
labscope or you would have posted waveforms for viewing. the fuel pressure
tests were normal? right? the first thing you check on a CIS car after you
make sure the fuel pump has more than twelve volts.Bestus,, Bill
