Best check 1st the sparkplug, compression and injector for that cylinder if you're talking about misfiring.

Well I already replaced the coil packs and plugs, the only thing I havent tested is the injector, but the thing is im getting no spark when I ground the plug. I guess the only way to check for a bad computer is grounding the coil pack to check for a little spark. But a bad injector will cause a missfire?

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
