no acceleration
 

my 1990 toyota 3.0 v6 has poor acceleration.just did the timing belt and the ignition timing is right on.but when i go to get on the highway or accelerate at all it bogs down. it didnt do this before so i guess my question is. could it be the timing marks on the crank and cams is off or is that even possible?

At this point, could be ANY NUMBER of a myriad of things. Try pulling codes first & let us know what you find.

Did you have any idea what you were doing when you changed the timing belt? It doesn't sound like it.....

Did you use the FSM?

try a tune up? fuel filter? air filter? auto or trans?

got it figured out.the keyway on the left cam sprocket was wore out.making the cam sprocket to move therefore messing with the timing
