5.4 Running Very Rough
98 Expe EB 5.4 - Last week I changed out all the COP's. Noticed an improvement right away. It was slightly rough between 1200-1500 rpm before the change. Now that went away. Throttle response felt a bit better. Well last night the wife says its running real rough and the whole truck shakes when driving. Today I start it up and notice a rough idle and I took it for a drive and yes the truck shakes slightly when driving. It feels like one cylinder isn't firing. When I blew a spark plug a couple of years ago, the truck drove the same way. Its just not making the loud popping sound it made from not having a spark plug in the hole. I rechecked all the connections. All COP plugs are tight. All injector plugs are tight. I checked all the hoses where I had to squeeze my hands through to make sure I didn't crack or disconnect any. They are all good. For a few seconds I thought I smelled fuel while I was looking at the passenger side. I couldn't see any leaks. The smell went away, though. New COP's are Accel from Summit. There is no CEL so far. I don't know if I should take it for a drive until one pops up. I don't feel comfortable driving it. Any thoughts, suggestions?
