changed timing belt (problem)

[jnr32r]

can any body help i changed the timing belt on my 32 and after everything was done and put back the right way the car is now going like shit the problem is its loss of power

the boost comes on but theres no sudden burst of pwer like there should be and it also back fires now when changing gears that didnt happen before

if anybody can help me out on this one and suggest what it could be, the problem that is that would be great.

thanks in advance.

did you put the cam belt cover back on?

Did you mark the crank angle sensor before removing it, then line it back up when re-fitting it?

Is there any possibility that the engine was turned while the old belt was off?

Did you ensure all timing marks were lined up?
