Because you took the time to criticize my reply when I said the OP needed a new mechanic.
And, yet, you never did answer my questions.
How would you have diagnosed it? You never did indicate what you would have done differently, or make any suggestions for the OP.
Yes, show me the freeze frame data. If there isnāt freeze frame data I need a description of the conditions when the problem occurred. And see post #17.
yes, more bells and whistles. No offense, but you do not come across like doing a lot of DIY repairs on cars. Save the money and stop at an auto parts store in your area the next time you have an engine check light on. They will usually retrieve engine check code for free and tell you the meaning of the code. Thatās precisely what 99% of OBD readers do. They wonāt tell you how to fix it.
When you lose the crank sensor the engine will stall, it wonāt cause one or two cylinders to drop out. If the crank sensor isnāt working how can the PCM detect misfires?
No offense taken. Youāre right Iām not a car repair guy. I can change my oil, filters, and bulbs, but Iām not comfortable messing with the engine. But I appreciate the suggestions on what might be causing this problem and hopefully will find the solution. Thanks for your help.
Umm, if a crank sensor fails, some (most?) Have more than 1 crank sensorā¦ and since it works on pulses, it will throw a code when the pulse doesnāt match up with the camshaft sensor, and initially default into ālimp modeā then a stall condition. It doesnāt know the position of the crank in relation to camshaft, which produces ugly issues. If itās intermittent, Iād try replacing each coil yourself, fairly easy job, and attempt to see which one causes the misfire. If itās intermittent, Iād replace all if itās feasible. But, with no crank or camshaft codes, and no stall or no start condition, Iād doubt seriously itās a crank sensor. Sticking valves, thatād be more of a constant problem that would go away with heat, in my logicā¦but Iām just a diyāerā¦
I hope someone else didnāt mention this, I donāt have much time right now, Dakotas are known to have and connector(s) problem to the computer, while running wiggle (Slightly) the connectors to see if it disappears. I was hunting for a truck and found a dakota with this problem, owner put a water bottle wedged between the computer and I forget what the other thingy was. Needless to say, I didnāt buy it because connectors are/were impossible to find unless you rewire the truck.
@dave_33770 Iām thinking it is something electrical and related to fuel supply. Misfired badly this past Friday and check engine light came one. Drove it into AutoZone and asked them to put on their analyzer. Got the 0300 for multiple engine misfires, multiple cylinders. But also got P0202 . See attached
A fuel injector fault stored in the PCM, that is some help. Have you returned to the shop to show them the misfire so that it could be diagnosed? Or do you intend to diagnose this yourself?
You wouldnāt think a fault with a single injector would cause misfires in all the cylinders. But sometimes the computer isnāt able to accurately identify which cylinder is misfiring. Best bet is to address the fuel injector problem first, as fixing that might solve the other problems too. Best of luck.
Hey Jeffā¦I have the identical problem with my 2004 Mitsubishi Raider
I was wondering what you found outā¦ please let me know as this is driving me crazy!
