My '02 Tacoma (144000mi.) started sputtering pretty bad yesterday after work. Check engine light was on so I went to the parts house and let them hook it up to the diagnostic thinger. "Cylinder 1 misfire" was the diagnosis. I had a set of plugs so I dropped a new one in and, as far as I can tell, it is running normaly now.
I have decided to replace the others first chance I get but I am thinking about changing out the coil packs too. Neighbor said he had seen some that looked worse but mine didn't look great by any means. Also had a guy at work who had the same issue in a different truck who changed only the plugs and then had to do the coil packs a few weeks later as the problem came back.
What say ye? Change the coil packs or not?
