Another timing belt question

[wh]

I replaced the belt and seals on my 93 impreza.
It starts and runs great but misses like crazy as soon as it warms up.
I have pulled and replaced the belt many times but am missing
something.
Any pointers?

have unplugged any sensors ???
make sure all the connections are tight

It's not the belt, check the spark plugs and wires and the coil pack. TG
