Check the fuel injectors and the fuel regualtor for leaks, mine was doing the same thing with the same codes and after replacing almost everything we totook the fuel injector spider out and you could see that the fuel regulator was leaking, replace the fuel regulator and that solved the problem

Have a 2004 Hyundai Santa Fe 3.5L v6. Added a fuel injector cleaner with a new tank of gas and now experiencing rough idling and getting error codes P0300, P0301, P0303, & P0305. What's going on?
P0300 is Random Misfire. 01, 03 and 05 narrows it down to those cylinders.

Clean throttle body and MAF, you may have carbon flaking off and fouling plugs. You could try taking it for a good thrash down the highway for an hour.

97 chevy tahoe running rough update....
code P0303 is a misfire code for cylinder # 3, Possible spark plug, wire/coil or injector problem. P0141, bank1 sensor2, is the upstream oxygen sensor, this code may have been set by the misfire of Cyl #3, the lean condition is being cause by the misfire. Fix the misfire and clear the codes and P0141 should not return. If the vehicle is equipped with Coil over plug system try swapping the coil with any one of the others, test drive and if the misfire code changes to another P0300 code ( P0301, P0302, P0304 etc...) the coil has failed and will need to be replaced.

I have a 2001 eclipse 3.0 it has a major loss of power and is using twice as much fuel the codes its throwing are P0135 p0141 p0300 I have replaced plugs and wires and will be ordering new sensors. After...
po135 andpo0141 refers to the oxygen sensors and p0300 refers to coils and injectors. . Replace faulty items. Use only genuine items as replacement as non-genuine are not always compatible with the OEM fitted CPU units. This
results in the fault codes not cancelling out.

1997 chevy blazer gets a po300 code and runs rough with no power. any suggestions?
p0300 is an engine misfire detected p0301 would be misfire detected on #1 cylinder and so no throught p0306SOo seeing its not related to any one cylinder i would check the crank shaft position sensor first because that and the cam shaft sensor is what detects all misfires Itcould also be caused by any of these sensors TP MAP IC VS ECT throttle position -manifold absuliute press -idle control -vehicle speed -engine coolant tempature By the way are you getting any codes or is your mil light on if so you should read the codes thatcould tell more then any one on line good luck
