First off, 4.7L, there is no plug wires on this engine, coil on plug, I suggest you do a compression test on this engine, if no compression on that cyl, pull the valve cover on that side and check to see if the rockers got out of place, this engine is famous for dislodge rockers in high mileage and low maintanece. if it 's popping through the throtlle body or tailpipe or clatter on first start of the day, thats your clue, I suggest you change the lash adjusters on that side, inspect the rockers for damage, replace if needed, with a screwdriver you can pop them in and out with no problems, make sure the cam lobes are up for each cyl, when you hear the snap sound, they are in place, not cheap, if no rockers out of place, burnt valve. Also make sure the injector and coil circuit are ok , you can swap injector to next door cyl and see if miss fire followed. GOOD LUCK, RDJRP

Change your spark plug wires, I would have started with that first.

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.

that is the coil on top of #5 spark plug. you can replace the coil or switch it to another cylinder and see if you get a different code. misfire codes are 301-306.

Auto question,I have an 96 Dodge Ram w/ 5.2L V8 eng.the problem is dtc codes P0300 and P0301,random multible cylinder misfire detected,and cylinder #1 misfire detected.Ive replaced the spark plugs, plug...


I would check the injector. Pull the plug and check for corrosion. Use on ohm meter to check the injector. The resistance should be 11 to 15 ohms. Check it against another injector. they should be close. You can also check the injector plug. best to use is a noid light, but you can use the meter. set it to dc volts to check. the numbers should jump everytime it fires. since you got a 300 and 301 misfire it tells me that you have an intermitant misfire in cylinder 1. The other sensors are still good don't replace them. The coil is still good, because when it starts to go, it will have misfires on all cylinders or will not work at all. The crank sensor is the one that detects the misfire, again don't replace it because it's not bad, it's just doing it's job. If the injector and harness check out good then I would start check the cylinder for compression and mechanical problems
