Emissions Question...

Sounds like it's running rich. Is the coolant thermostat stuck open? Happened to me.

Not that I can tell. I replaced the spark plugs a few months ago, so we're good there. A friend of mine stated I should decarbonize the motor, clean out the throttle body, replace gas with good quality higher octane gas and dump in some BG 44K then go back after running it for about 30 minutes. Thoughts?

Snake oil, and TFOGGER stole my thunder by posting before I could change from a iPad to a computer.

I will add just one question. Is there a check engine light?

No. There are no "Service Engine Soon" or "Check Engine Lights" whatsoever. The only fail was the HC & CO. Also, how often should you replace spark plug wires. I replaced them in 2007. The car fires right up but tends to idle real low and does die on occassion at red lights. I was told that is most likely carbon build up on the Idle Air Control Valve.

When you change the plugs. Go get yourself a GOOD set of plug wires (this isn't coil on plug correct?), change the oil, check your air cleaner and you will probably pass.


ETA: Also, while they don't require high end double throw down triple platinum plugs you don't want crap in there. What brand did you use?

Correct, it runs from distributor to plug. Also, I used Champion plugs (nothing fancy) but if I need to, I'll replace them with something better. Perhaps I'll pick up a set of good plug wires while I'm at it. Any recommendations there tmleadr03?

NGK for plugs. No question. Some of the best plugs out there and for your engine not that expensive. Champion are... no.

For plug wires, I would say what NAPA or Carquest has as a "Top Shelf" brand should be perfect. This isn't really the type of car I am intimately familiar with so I am not entirely certain what plug wires are decent. 99% of the cars I work on don't use plug wires.
