My wifes 95, 2 weeks after passing smog test, pops CEL light. I hook up my Innova obd 1 -2, and it doesn't work. so I do the jumper wire thing, and up pops 337= EGR valve. Change egr valve= drop the engine. Sent tester to innova, and they said nothing wrong, but it works when I got it back. Pops same code, but tells me it's the DPFE, air diverter. Changed it (without dropping engine), and cel light has gone away, and no codes to be found. That tester saved me a lot of $$. For you guys that don't know the Gen 1, these parts are between the rear of the engine, and the firewall. I was happy to cross that one off of the list.
