TX's The check engine light is not on. Will check the EGR and Cat. Thinking since the HC was high the cat may be going out too. Have new oxigen sensor and seals. Really can't drop too much money in it.

Finally got the egr valve changed and it still failed. Down to 4.8553 so almost there. The cat is susposedly good it "passed" dianostics. Any other ideas to get it the rest of the way there?

MAYBE A FULL 100% TUNE UP?

. OR JUST CATCH UP ON YOUR SCHEDULED MAINTENANCE (BEST WAY IS READ AND ADHERE TO THAT SECTION, IN A REPAIR MANUAL (ABOUT $30)

THE BETTER OPTIONS ARE:

1) OBTAIN AN OLDER VEHICLE (OF YOUR LIKINGS) THAT IS NO LONGER REQUIRED TO TAKE THE TESTS. YOU'LL THEN HAVE A HEAD TURNING CLASSIC, EZ TO DIAGNOSE/REPAIR, EVEN A FULL RESTORATION COULD BE CHEAPER THAN A "NEW COMPLICATED OVER ENGINEERED RIG" (MINE ARE 35 AND 66 YEARS YOUNG, BOTH ARE DAILY DRIVERS)

DON'T LIKE THEM SEAT BELTS. IF THE CAR DID NOT HAVE ANY ORIGINALLY FROM THE FACTORY(AROUND 1963), YOU ARE NOT REQUIRED TO HAVE/ WEAR 'EM. IF YOU REALLY DESIRE AN AIRBAG, FIND AND LET MY EX-WIFE RIDE WITH YOU!

2) MOVE TO A STATE LIKE MINE---AIN'T NONE OF THAT TESTING!

GOSH, I GIVE REALLY GOOD OPTIONS!
