Hi Guys,

Car is a 1987 245. Recently failed Maryland emission treadmill test with high NOx. Numbers for emissions were: HC - .8053 GPM (PASS); CO - 1.6733 GPM (PASS); and NOx - 4.6454 (FAIL - state standard is 2.8 GPM).

Any ideas on where I should look or what I should adjust or replace to get this thing passed ?

Thanks.

Mike
