Engine Performance problem
1995 Plymouth Voyager 6 cyl Front Wheel Drive Automatic 252000 miles
Can you folks decipher this emissions report results
HCppm. 200/90 pass
CO%. 1.00/1.02 fail
NOppm. N/a n/a
HCppm. 54/56 fail
NOppm. 757/256 pass
It was so close to passing. Seafoam treated, new plug wires, 6mos old plugs, diaelectric grease, new air filter, oil change 10w-30, gas antifreeze w/91 octane, shrouded pipe leading to cat, new pcv valve. Did I miss something? Based on the results, what could it be? Help!
