You can try changing the coils, rotor cap and distributor. See if that helps.

2003 acura tl error codes po301 po302 po304 po306 p1399 po300


PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

P0300 Code 99 Chevrolet silverado 1500 5.3L


Random misfire. Computer cannot figure out which cylinder is misfiring or it occurs randomly on all 8 cylinders. A friend of mine found his ABS system was kicking in while driving down the road, feeling like the engine was missing. Computer detected it as a P0300 random misfire. He removed ABS fuse and eliminated the problem.

ENGINE MISFIRE

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Hooked up computer to dodge ram 1500 4.7 liter magnum code came up p300 p301 what does this mean


P0300 is the random misfire code. P0301 is the misfire code for Cylinder #1. When was your last tune up? non platinum spark plugs should be replaced around 30-60k along with the wires. With platinum plugs that extends out to 100k. I would try a tune up first plugs and wires. Reasonably cheap fix that is a prevenitive maintenace item anyways. If you have just recently had a tune up or it does not solve your problem you most likely have a bad coil pack on cylinder#1.

Hope This Helps.

WHAT IS THE CAUSE OF THE PO301 CODE?


The error code p0301 ,This code is related to misfire.The cylinder is misfiring. p0301 this is the indication of cylinder number 1 ,that is misfiring.If the code comes up as p0300 this is the indication of random misfire from all the cylinders.But in your case its indicating p0301 this is indication of cylinder 1 misfire.Check cylinder 1 and replace the faulty cylinder 1 to clear the fault.The spark plugs and the wires connecting to spark plugs also needs to be checked. Keep updated with any more query.Thanks.

2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

Code 301, random or cylinder 1 misfire


Spake pluge could have gone bad, or the Spark Plug wire. Try changing all your plugs and wire and inspect the old one's. The wire could be bad do to time or may have been against the exhaust manifold and brunt. Good luck
