I have a 1990 seville. I have replaced the fuel pump,filter set the timming and I am still getting loss of power. I found in the ecm information that the following is happening, 128 LINT FUEL ED 36, 176 RINT FUEL ED 37, 130 L B/L FUEL ED38, 160 R B/L RUEL ED 39, 7.0 MS LINJ PW ED30, 9.2 MS RINJ PW ED31, .57 LOXY SNS ED32, .40 ROXY SENS ED33, 8 LCROSS CTS ED34, AND 0 R CROSS CTS ED35. What is going on. I have also replaced the plugs and plug wires. I am thinking it something with fuel system. The EGR checks out. Fuel economy has dropped from 27 down to 16 mpg.
