Hi, so i have a 87 Hardbody 4x4 with the Z24 motor, it has 290,650km on it runs good. The problem is when I am driving in 2nd 3rd or 4th and the revs are over 3000 and I give it more then half gas the truck starts to shudder/bog down, it does slowly speed up but does not power through the shudder/bogging. If i take the air cleaner cover off it does get better but is still there. Any ideas of what it could be? I put some fuel system cleaner in the tank tonight and I am going to change all 8 plugs tomorrow in the morning.
Thanks
Matt
