I HAVE THE SAME PROBLEM, REPLACED PLUGS AND WIRES ,CHECKED FOR VACCIUM LEAKS , COMPRESSION TEST, CLEANED FUEL INJECTORS. DON'T WANT TO KEEP GUESSING.
Do a compression test of the #5 cylinder. It's usually a good idea to do a compression test, when there is misfire on a cylinder, it takes only a few minutes. Then you know that the cylinder is sealing and you can then replace either the plug, coil, wire etc. It could also be a vacuum leak near that cylinder.
i found that i have gotten a bad new plug try swapping plugs around and see if it follows the plug from the problem cyl.
P.C.M. computer is going badd.costs a1000.00$ to fix.
REPLACED COIL AND HAVEN'T HAD ANY PROBLEMS.
no vacuum leaks found compression is 175
no vacuum leaks found and compression on #5 is 175 i heard a flywheel can cause this is that true?
