I have no idea.
So this problem just came out of no where. What happens is when i have the clutch in and then i let it out in second sometimes the clutch will be all the way out and the foot to the floor and no rpms at all. It will do it when i shift to 3rd and fourth and then i just let off and step on the gas agian and it comes back to life. I replaced the air filter and fuel filter and put some lucas injectore cleaner in my tank. Any ideas? The truck also seems to have a hard time starting off from second, like it shakes and i have to give it more gas then i should have to.
