SOURCE: 1997 ram 1500 5.9 wont rev past 2000 rpm

well, the timing on your ram is computer controlled. is the truck in drive when this mis-fire occurs? or at idle? youve addressed part of your ignition w/the cap-rotor-plug wires. did you examine the old cap for carbon tracking? did you install the rotor properly? i know on my '97 ram the dist is feakin' buried in the engine it would be easy to rotate the rotor while installing/removing it so the timing mark is off. does your engine have the right plugs installed? your plug wires follow the correct firing order with your dist? you did not mention anything about your ignition coil. here is how to safely remove and check your ignition coil. disconnect battery-at the coil disconnect the lead wire (TOP) and primary (BOTTOM) from the coil. label your wires, or take a pic of your ign coil before you remove it so if you forget where the wires go, you have reference point. remove mounting screws and remove coil. clean coil to remove rust/dirt and wipe coil terminals off. inspect case for damage. with a multi-meter, check coil primary resistance by selecting ohm's and then place + and - leads on the pos/neg terminals on the coil, dodge used 2 brands of coils either a "diamond" or a "denso" primary resistance for the diamond mfr'd coil will be between 0.97-1.18 ohms. secondary resistance 11,300-15,300 ohms. Denso primary resistance 0.95-1.20 secondary resistance of 11,300-13,300 ohms. to measure secondary resistance place one of the leads to one the primary terminals and the other lead attatch to the large center terminal. compare your readings to the above values. if your readings are not within range of the above values, your problem is the ignition coil. other causes you may consider is faulty: speed sensor, throttle pos sensor/trans issues like bad pressure solenoid (actuates gear changes) a fault in your overdrive system. hope i have helped!

SOURCE: 2005 chrysler 300c misfiring cylinder

I have a 2006 5.7 Hemi 300C AWD - #4 cylinder started to misfire at idle. Problem just happened without cause on a Sunday morning. Dealership mechanics have exchanges coils, PCM, etc. problem stays with #4 and is sporadic (soemtiem cold idle, sometimes hot). Happened after a new fill of 90 octane gas from Shell (always use this station, never any previous problems). Car is in perfect shape, with only the dealer ever touching it at every req. maintenance schedule. Today they are pulling the head to check for valve issues. SMART troubleshooting trees and TSB's are no help so far. Anyone else with a solution?

Check the coil out put.
Loosen the wires from the plugs with the engine off then find some plastic plyers or an insulated tool to remove the wire without getting shocked.
Start the car and one by one remove and replace each wire to see which one does not make a difference in the way the engine runs. Thats the one that probably has a bad coil.

I have a 2007 300c awd hemi. i had the check engine ight come on. google said to pull the number 11 fuse now the car wont start. do i have to reset the computer


Did you put back. Pulling a fuse will not reset the light you have a problem the only way to do that is find out what is wrong. I think starting problem was caused by pulling the fuse. Put fuse back and give me an update

2005 Chrysler 300 hemi. Engine quit going down road and will not restart. I believe it is the fuel pump. Last few times the tank was filled it would stall and die. would have to restart several times ...


The fuel pump is a good place to start since I doubt if the timing belt has broken in a vehicle this new unless you have been racing it. Yes, the pump is submerged in the tank. It could also be the fuel filter and that should be located under the passenger side of the vehicle near the gas tank itself.

You have a loose heat shield or a broken rubber mount.

jack your car up make sure you put some thing under need like a jack stand ( just for safety) and manually shake your muffler usually rattling noises are cause when metal rubes metal.
