After I replace spark plus (found one cracked when I took it out), replace Rotor and Distributors. I did not replace Wires, they are fairly new-3 years and in great condition.
But second test result got worse:
HC Cruise limit 170 pass at 31 --much better, Idle limit 220 failed at 223.
CO Cruise Limit 1.2 pass at 0.09 --much better, Idle limit 1.2 failed at 2.53.
Both idle condition are much worse. I drive (at 9am) to the test center about 5 miles from my home after I replace the parts a night before.
What do you think the problem is and can I be able to fix it myself or get a teachnician to fix it?
Thank you very much for your help.
