Truck does not go over about half throttle
I have a 98.5 24 valve. Starts and runs great except whenitt gets to about half throtttle it falls on its face. Looses power also the tach does not work. If you feather the throttle it will get up to speed but if you lay into it, it just won't go. When you let off a little it takes off. Any ideas?
