Of course it started stuttering right before emissions time. Came on rather
Noticable stutter under load but drivable, less noticable at higher speeds.
Had the emissions test anyway to help diagnose. Can't afford too much on
this good old car. Plugs look fine and balanced, with the low NOx it
doesn't seem to be EGR. Obviously running rich but I'm not thinking oxygen
sensor as it degraded fast.
Any ideas appreciated.
1725rpm max is
HC (PPM) 203 1097
CO % 1.15 1.17
NOx 1577 312
