Hey guys I got my 1299 Honda Prelude today, and it had a misfire on cylinder 2, so I got new spark plugs, cleaned up the cap and rotor, and it is still idling like sh*t. Any ideas on what it could be? Thanks!

Thanks a bunch!

 

I know NickGREPSMN personally and I actually drove it home.

It was throwing a P0302 and a P1399 for a cylinder misfire on 2 and a ignition control system/random misfire on all cylinders.

We replaced to stupid corroded plugs, did and oil change, CLEANED (which is all we could do at the moment being a weekend and refusing to run anything but Honda parts) the cap and rotor. As of Monday the cap and rotor will be replaced and the wires will be thoroughly inspected in the dark with a water bottle. We also ran Lucas injector cleaner through the system with a fuel filter also being replaced on Monday. We will most likely clean/replace gaskets the throttle body tomorrow as well, including a billet block off plate for the FITV to keep things simple. Thanks for the reply though.
