Ok, I'm ast the end of my rope here. I'm flunking the NY state
emissions on HC's. Cutpoint's .80, I'm at 1.0. NOx and CO are
virtually nil, like 1/4 or less the limit:
* Put in a new cat. No real change.
* Put in new plugs, wires, coils. No help.
* Changed the fuel filter. Old one was plugged badly. This got me from
1.45 to 1.0.
* Changed the thermostat. Not checked it yet but the thing stays in
more or less the same temp range anyway.
* O2 sensor. Was ok.
I'm thinking either ignition related, vacuum leak (but where?), or fuel pump/pressure regulator, maybe? I mean, what else is there? Slip the tester $75 and be done with it?
