Since the compression is good I would not expect it to be a burnt valve. It could be timing if the timing chain has excess play. I would also check the ignition module and the engine control module. We had a 1986 Chevy Celebrity that had an ignition problem that cause it to run badly and backfire. The service engine soon light was blinking but not posting a code. We changed the engine control module and it fixed the problem.

Well it could be that your timing might be off if it didnt backfire before,i would get the timing checked or go back to where you got it done.

It depends on why the compression is low. Assuming you checked compression with a gauge causes could include a stuck valve or valves, blown head gasket, cracked head or bad rings and seals. Repair requirements in order are a valve job, a new head gasket installation, a new or rebuilt head, a new or rebuilt engine.
