Hello and welcome to just answer. Are the CO and NOX readings within limits? And what are the actual HC readings?

Chris

Customer: replied 11 months ago.
The co and NOX readings are within limits the HC readings are 2.65 first time and 2.77 second time thru test needs to be 2.50.

Ok, High Hc is caused by misfires or incomplete combustion. A weak catalytic converter can also cause high HC. Perform a tune up (spark plugs, wires, cap and rotor) then run a bottle of Sea Foam injector cleaner through the tank at the next fill up. Hopefully this will help. If not, then suspect the catalytic converter and have it replaced.

I hope that this information is helpful and please let me know if you need further assistance.

I had ran a can of 44k in a tank of gas then filled with premium for the second test and the # ***** up. I'm going to replace plugs and change oil try again

Ok, keep me posted. If the hc still is too high, then consider replacing the catalytic converter.
