Clogged injector, HELP!

:banghead: Just changed the gas tank on my 89 dx hatch (stock) and then it started stalling while i was driving. It wouldn't completely shut off , just not respond to the throttle for a few seconds. Then i'll tap on the gas a couple of times and it would go back to normal. this keeps on happening. I gave it a complete tune up and checked the fuel pump so its not those things. I think the injectors are clogged, does anyone know how to fix them. Moneys tight, thanks to bloomberg. If anyone can help i'd appreciate it.

when you put you fuel tank back up make sure you dint crimp one of the fuel lines. i replace the fuel pump and when i put the tank back up it was hitting a line. then i replace the feul filter after that
and it dint start at all.
make sure you dint do that.
also go get some fuel injector cleaner see if that helps.
