how much is ok just got oem gm and it seems to have about 1mm of play.
i dont want to put it in just to have it run worse than it does now.i already
have code p300 but i pulled the plugs they were a whiteish grey and none
were fouled but i have low rpm miss at 1500 rpm and it surges at idel. and
i changed wires. it runs fine till it warms up then seems down on power.
i only have 2500 miles on new motor.

 

mine moved a little when i bought it

 

Every one I have purchased had play. It is only one bearing you know and that bearing has to have play to accomodate heat expansion.

 

thanks i just dont want any more problems . i have had so many and i have had
to replace a lot of new parts gm and other brands .since it has ben rebulit
2500 miles ago .thank god my mustang 5.0 it has not let me down like the trans am
you will laugh i towed it home once with my mustang but i love both cars
so i keep putting more money in the trans am one day i hope it will be happy
thanks for your guys help!
