no problem. If you are getting that low of voltage on a load then you might want to test the alternator as well to make sure it is running at capacity.

SOURCE: 04 Ranger rough idle
I would check your crankshaft positing sensor this may be bad. I would also change your spark plugs and wires becuase they may have got water in them causing a short between them and the head. I would very carefully use air to clean the dirt from your engine compartment first. Autozone runs a free code check for you and this will tell you your problem. To clear your codes and to make the check engine light go off take off your battery cables and wait 30 minutes. You may also have a bad coil which will cause a misfire as well and a 306 error means a misfire to your 6th cylinder so it's probaly this. I hope this information helps.

Could be many things, Check the EGR valve and make sure its not stuck open, Oil pressure low is probably due to rough idle or low RPM. Also may have restricted cat converter.
