Chemical test ok, replaced plugs and plug boots, reset computer, started and it spit and sputtered and died, drove 15 miles and had codes pulled P0300, P0420. Also from the day I bought the car the seatbelt, ETS, airbag and check engine light all come on when car is started and remain constant till ignition is turned off! ETS button on gear shift does nothing, I tested ETS button with multi meter, button is good, I'm assuming it's a wheel speed sensor, I have a friend bringing a diagnostic computer over to hook up and drive the car for more detailed info, I'm assuming airbag light it a bad floor board sensor or corroded sensor? I cleaned seat belt contacts and checked seat belt wires "even spliced them together" and seat belt light is still on. Now as far as engine codes I've been told catalytic converter, clogged egr, vacuum line, ext. Now I definitely heard arcing "no visible arc" coming from under the plug cover, possible ignition coil pack housing? Open to all comments, ideas, and knowledge! Thanks Guys!
