1999 DODGE VIPER GTS COUPE--REPLACED BATTERY---CAR WONT PASS SMOG---CATS NOT READY??? WHAT DO WE DO-----
Had to do the same when my battery died. Drove on the freeway for 50 miles at a continuous speed. Passed with no problems.Several years ago the same thing happened to me when I brought my rarely driven 02 RT10 in for emissions. They were not getting a reading. So, i took it on a 50-mile drive, then came back and passed the test.
