This 90 seville is running rich and stumbles when it starts and nearly stalls o2 right side shows no fluctuation or cross counts have checked fuel pressure. Vac leaks, egr, fuel leak down, changed o2s, checked tp to no avail. Also scan tool blinks to no data on occassion as well as all dash power. Hope you have an idea

thanks Kerry
