I Have a 1993 Lexus SC400. I bought a diagnostic tester Innova 1203 CANOBDI and I cannot get this car to read. It just comes back no data. I bought a test light and it has power going to the connections. The car runs for awhile then when it heats up it just goes blog. The RPMS go with my foot off the gas when it is idiling. The car runs rough, like it wants to die. I have to keep my foot on the gas peddle to keep it running. I changed out my fuel filter 2 times and the fuel pump. I just do not understand why the computer won't read on the diagnostic? Can you help?
have the same problem?
