Engine Codes 2007 Honda Fit Sport
I have 63309 miles on my 07 fit sport. I was feeling a weird popping or misfire for a about a month now. So i hooked up the carmd to the computer port of the car. I got some codes back and want to know how i can fix them. They all seem to be for the problem that i think i was having.
P0302 Cylinder 2 Misfire Detected - This fault code indicates the Misfire Monitor has detected that a misfire in Cylinder 2 was detected. The vehicle’s computer continuously checks for engine misfires and identifies the specific cylinder or cylinders in which the misfire occurred. The Misfire Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite properly due to the absence or incorrect proportions of spark, air and fuel in the combustion chamber. Possible Causes:
Fuel system problem affecting only Cylinder 2
Ignition system problem affecting Cylinder 2
Base engine (mechanical) problem affecting only Cylinder 2
Condition For Setting The Code:
DTC P0107, P0108, P0131, P0132, P0171, P0172, P1128, P0335, P0336, P0505, P1128, P1129, P1259, P1361, P1362, P1366, P1367 and P1519 not set, engine running under positive torque conditions, and the PCM detected a misfire condition in one cylinder. Note: If the misfire is severe, the MIL will flash on/off on the 1st trip!
P0301 Cylinder 1 Misfire Detected - This fault code indicates the Misfire Monitor has detected that a misfire in Cylinder 1 was detected. The vehicle’s computer continuously checks for engine misfires and identifies the specific cylinder or cylinders in which the misfire occurred. The Misfire Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite properly due to the absence or incorrect proportions of spark, air and fuel in the combustion chamber. Possible Causes:
Faulty spark plug
Faulty ignition coil
Faulty fuel injector
Faulty fuel pump and/or regulator
Poor connections or loose terminals at the ignition coil, the injector, and the PCM
"Open" or "Short" circuit between the ignition coil and the under-hood fuse/relay box
"Open" or "Short" circuit between the PCM and the ignition coil
Internal engine problem
Incorrect PCM idle learn procedure
Incorrect CKP pattern learn procedure
MAF sensor
Condition For Setting The Code:
The execution time is once per driving cycle and the duration time is 200 revolutions for Type 1 and 1,000 revolutions for Type 2. Conditions for illuminating the MIL Type 1 and Type 2. * Misfire Type 1 (Severe) Per 200 revolutions 27-90 times. If a type 1 misfire (catalyst damaging) occurs once, the MIL blinks once per second, a Temporary DTC is stored, and the high rpm fuel injection stop system activates. The fuel injection stops, at high rpm only, on the cylinder that has the highest misfire counts. the MIL continues to blink, and the fuel injection stays off at high rpm, until the drive is completed. If a type 1 misfire occurs during a second drive cycle, the MIL and fuel injection behave the same and a DTC is stored. After a type 1 misfire has been detected during two drive cycles, the MIL comes on and stays on beginning with the third drive cycle, unless the Temporary DTC has been cleared by the PCM. Even if the MIL is on, it will start blinking if a type 1 misfire occurs. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the freeze frame data are stored. * Misfire Type 2 (Light) Per 1,000 revolutions 55 times. If a type 2 misfire (emission-related but not severe enough to immediately damage the catalyst) occurs, a Temporary DTC is stored, but the MIL does come on or blink. If a type 2 misfire occurs during a second drive cycle, the MIL comes on and stays on unless the Temporary DTC has been cleared by the PCM. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
P0300 Random Misfire Detected - This fault code indicates the Misfire Monitor has detected that multiple misfires in multiple random cylinders (the misfire is not isolated to a single cylinder) were detected. The vehicle’s computer continuously checks for engine misfires and identifies the specific cylinder or cylinders in which the misfire occurred. The Misfire Monitor continuously checks for engine misfires. A misfire occurs when the air-fuel mixture in the cylinder does not ignite properly due to the absence or incorrect proportions of spark, air and fuel in the combustion chamber. Possible Causes:
Poor fuel quality
Clogged fuel filter
Faulty spark plugs
Faulty Fuel pump and/or regulator
Poor connections or loose terminals at the ignition coil, the injector, and the PCM
Check the CKP pattern learn procedure
Condition For Setting The Code:
The execution time is once per driving cycle and the duration time is 200 revolutions for Type 1 and 1,000 revolutions for Type 2. Conditions for illuminating the MIL Type 1 and Type 2. * Misfire Type 1 (Severe) Per 200 revolutions 27-90 times. If a type 1 misfire (catalyst damaging) occurs once, the MIL blinks once per second, a Temporary DTC is stored, and the high rpm fuel injection stop system activates.

How i fix this?
