i check and when the #1 piston is at TDC the timing mark
is at zero

the problem is if you put a timing light on it and you
put the mark on 2-12 degrees

the motor knocks very loud and if you back the timing off
it runs good but with no power

i just bought the truck so i dont know what kind of work has been done to it

thanks

how do you check thoses

would it do that if the timeing belt jumped a tooth

if its a 22re it doent have a timming belt. it has a chain. and i doubt that it has jumped a tooth.do a diagnostic check on the computer. are u getting a check engine light?search tps and figure out how to test it. does the timming jump around alot when u are trying to set it?
