I am new on here but have owned my truck for many years, due in part to gas mileage and a divorce it has done a lot of sitting 88k miles on her now. I have had the coil packs replaced several times and the ECM also(warranty), then I was told it could be the valves sticking.. during all this time the truck acted like it was one or two cyc down. This is now my daily driver because it has my chair lift on it so I need to make sure it's running right
. I just did a plug/wire change and all coil packs are firing, intake was seafoamed, not sure if that helped or was a placebo effect. but she is still running rough with "limited" power and a un burned gas smell while running. This is NOTHING new except the gas smell, but I would like to fix it finally. ANY HELP IS WELCOME AND APPRECIATED!
