Here is the run down. I live in Mass (hellish emissions laws) and can't get my 86 FJ60 to pass emissons.
I've inspected the rig 4 times now, and still can't get the CO levels low enough to pass.
Here's what I've done.
Installed new Catalytic converter
Installed Man-a-fre Header to replace cracked manifold (this requires the removal of the EGR cooler/EGR Plenum...possible prolem area???)
Changed Spark plugs
Went through ALL vacuum lines, and replaced any in question
Changed the oil
Cleaned the Carb
Cleaned the air filter
I've also adjusted the carb, and brought it in running rich and running lean. When I lean the carb out, the CO levels come down, but not enough. At this point, I'm at a loss. If anyone has any suggestion on how to reduce my CO output, that would be awsome!
Some mentioned I should contact Jim C?/?? sooo...you out there Jim C???? Any suggestions? I'm the guy with the green FJ60 you met at the Fall Gathering in NH a month back!!!
Cheers,
JON
