My 96 honda accord is giving me three different code readings they are: P0303 cylinder 3 missfire, P0302 cylinder 2 missfire & P1300 multiple missfire detected, How do I fix this problem?

171 is fuel in lean condition, and 303 is misfire on cylinder three. The first few things I would check is, fuel injector on cylinder three, the coil, and the spark plug.

Sounds like what's called a "dead Cylinder". Have it tested for the codes and the one number on the end of the code will tell you which cylinder is misfiring. A code like P0303 means it's #3 cylinder. It could only be a faulty fuel injector, but be ready for something worse. Once you know which one, do an ohm-meter test on each injector unplugged. If it shows a much lower reading on #3, just change the injector. If no difference in readings, do a compression test on all cylinders with all plugs out. This could show you've a faulty valve on a cylinder with very low compression compared to the others.

Codes p0300 random misfire, p0302-0304 misfire cylinder 2-4. P0133 o2 circuit slow response bank 1 sensor 1. P1176, P1300, P1580, P1543, B0423 r make specific which you didn't say this would cause the problems you are having.

replace distributor cap and rotor.could have faulty spark plug or wire.could have faulty fuel injector to cylinder 3. or injector wiring has a short.PCM faulty not firing injector number 3.could have mechanical problem like burned out valves intake manifold leak near cylinder 3.

the po303 is cylinder 3 misfire and other code could be trans code or abs or body code i know yhe one for sure

here is the code table: code table, hope it can help you

is there oil leaking into that plug area?

CODE P1300 IS MISFIRE DETECTED FUEL PROBLEM. WHICH MEAN 3 FUEL INJECTOR IS CLOGGED UP.HAVE FUEL INJECTORS CLEAN AND CHANGE FUEL FILTER.

take sample of your fuel into clear plastic bottle from fuel line
is there any water present?
this can cause these codes and then not go on storing codes for other bank even though that bank will be missfiring also due to water & P0300 Random/Multiple Cylinder Misfire Detected being logged
check all connections to coils/leads & wiring connectors
due to miss fire codes for cyl 1,3,5 all on the same bank
also look and check for air leaks on that bank (hose knocked off or splithose)inlet manifold gasket,brake booster etc...
3 injectors being blocked slightly on same bank posible!!!
check wires and signal

was it running like this b4 tune up & repairs?
this is what codes are
P0170 Fuel Trim Malfunction (Bank 1)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0305 Cylinder 5 Misfire Detected

the last code is for trans due to misfire/running lean on bank 1 probably a torque problem code

P1127 Long Term Fuel Trim mult.,Bank1 System too Rich

P1129 Long Term Fuel Trim mult.,Bank2 System too Rich

P1250 Fuel Level Too Low

P1300 Misfire detected Reason: Fuel level too low

P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

P0300 Random/Multiple Cylinder Misfire Detected

P0303 Cylinder 3 Misfire Detected

P0304 Cylinder 4 Misfire Detected

It sounds like there is a lot going on.

Good Luck
