My car became sluggish, hard to start, lost power and bogged out at stops. Code read engine misfire. I replaced coils and reset computer problem still existed, code read ignition control module, replaced that reset computer. Still persisted code read crankshaft control module, replaced that and problem still continues. Any idea what it could be without having to replace everything along the way?

On misfires I direct everyone to go to a local professional so he/she can hook up their scanner as it can be an injector, any sensor as well as a basic engine problem. this is your cheapest option. you can check for a vacuum leak as well as fuel pressure , auto parts rent gauge.
