I had scan tool hooked up to the car after the check engine light came on and it said it was mis-firing on cylinder 2 and 5 more than once. Before the check engine light came on I had replaced the spark plugs and gapped them correctly with Bosch platiums - because I felt is was misfiring. After the scantool gave me the misfire reading, I replaced the wires, cap and rotor, timing belt, and drive belt. It still misfires. What do I do now? Thanks

Had a similar problem, put the plats in, along with a new bosch cap & rotor, CE light came on, misfire codes. Everyone told me to trash the plugs and put in OEM copper, so I did, light came back on. For kicks I replaced the cap and rotor again, never reset the light, but in 2 days it went off on its own.... Bottom line, I've read a number of posts on other board about plat plugs causing the CE light to go on.
