Hi,welcome to Just Answer.I will be happy to assist you with this question today.I will try and assist you as best as possible from here,feel free to ask any follow up questions to my info provided here.Did you remove the catalytic converters or open up the exhaust on one or both sides to see if it operates normally?Has spark been tested at all on all of the cylinders?Do you know what cylinders are misfiring?Let me know so we can continue,thanks Pete!
I have open up the exuast before the cats ===no change
while eng is runing i individualy unpluged each coil and the eng would respond to the loss of spark
the code that comes up is random multible misfire
no it has gradualy been getting worse since january and the truck has been a daily driver
i first notice when i would have the boat behind it
