Ok folk's Torrance, Ca. aka South Bay. Any body know of a good dealer for chasing an injector knock. I got one but dont want it. 44k miles, started about 1500 to 2000 miles ago so I know its not fuel, also my milage has gone from 21-22 down to 15-16. Filter changed about 800 miles ago. I've had two TSB's done at GLENN E THOMAS in LB, but they were not engine related. on 2nd gens. they seem decent, but 3rd gen's ??????
