Jeep Wrangler Code P0300
notes The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem, see "Possible 2004 jeep liberty asd relay Causes" What does this mean? When is the code detected?The control module monitors the crankshaft speed and has detected a misfire condition Possible symptoms- Engine Light ON (or Service Engine Soon Warning Light)- Lack/loss of power- Hard start- Engine hesitation P0300 Jeep Description When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring. Need more help?

week later it through the Multiple misfire code. I started by replacing the spark plugs. The old ones were from 20K miles ago and still looked good. Replaced them anyway. I still had the code. I put K44 fuel injector cleaner into the tank and drove it home (2 miles.) The next morning I started it and went in side because I had forgotten something. I came out to extremely thick black smoke. It went away after about 2 minutes, the computer code cleared, and the engine idled perfectly. About 2000 miles later the car is once again idling poorly. I added K44 again and for that tank of gas it ran fine, no code. Once new gas was added it threw the same error code and idles very roughly. So here are some basic info pieces1. 8 tanks of gas from 8 different locations.2. Adding K44 has shown a direct improvement both times, but more significant the 1st time.3. New spark plugs4. New coil packs5. 2005 Jeep Liberty - 3.7L V6 at 99,872 miles6. Hopefully unrelated is that the car has a small radiator fluid leak I haven't found. It requires 1/2 gallon every 2K miles or so. Generally the solutions to this problem seem to be electrical, but that doesn't seem to jive with the K44 helping. There is no knocking sound, it just sounds like there isn't enough gas. Car responds fine to accelerator. Above 10mph car seems to drive smoothly. cigroller 2012-01-21 05:21:51 UTC #2 Given the coolant loss I wouldn't do another thing until I checked the compression. If its found to be low you'd want a leakdown test the see about the head gasket. Quicker/easier checks might be a block tester and/or a vacuum gauge. Aside from that I saw no reference to new wires to go with those new plugs & coil packs. You also need to check out the fuel system - fuel pressure & the fuel pressure regulator at minimum.

Tester 2012-01-21 05:51:45 UTC #4 One thing to try is obtain a aerosol can of MAF sensor cleaner and remove and clean the MAF sensor. The MAF sensor is a primary input into the computer. And as it heats up and there's debris on the wire elements it doesn't measure the proper amount of air entering the engine. This then causes multiple/random misfires and codes. This is about the cheapest thing to try other than connecting a professional scanner to determine if the MAF sensor is the problem. I've expeirienced ma
