Re: Failed. Reply #1 – October 01, 2005, 09:17:04 AM The usual suspect in high NOx readings is the EGR system.Do you still have one? Quote Selected

Re: Failed. Reply #3 – October 01, 2005, 08:17:17 PM Lean MAYBE...NOx is from high exhaust temps...(maybe lean) Ck EGR system, Ck plugs not too wide a gap and correct heat range,Ck air filter,ck fuel pressure and regulator, run 93 octane...higher octane is "slower" burning and may "cool" the exhaust gas just enough...and possibly the "CAT"(pun intended ) convertors are on the way out or dead... :D Quote Selected
