I have a 99 and I have been having some missing/idling problems, you can't really see the tack move just feel it shake. It doesn't throw a code... It all started after I changed my plugs and wires.. Here is what I have tried so far; changed plugs and wires a 2nd time, cleaned throttle body, seafoam, replaced pcv, only run 93 in gas..

any other ideas on what it maybe??

The obvious-Are all the wires on snug (both ends) heard them click on? Are all the wires on the correct plugs? All the plugs are gapped and seated correctly? Coil wire is snug?

Have you replaced the fuel filter?
