My firebird has had trouble with the injectors. We have had them cleaned out. Before having that done we changed the plugs and the wires before figuring it out that the injectors were clogged. We did all this about a year ago. The same problem if not worse is back. Can it be the injectors again? Thank You for your time.

Her is everything I know that can cause a miss:
1 Fuel filter clogged or impurites in fule system
2 Faulty or incorrect gapped spark plugs
3 Cracked distributer cap-if equipped-or damaged or disconnected ignition system wires
4 defective spark plug wires
5 incorrect ignition timing
6 Emissions system compoinents faulty
7 Low or uneven cylinder compression pressures
8 weak or faulty ignition coil(s)
9 weak or faulty ignition system
10 Vacuum leaks at intake manifold or plenum or hoses
11 dirty or clogged fuel injector
Hope this helps, reply when problem is solved
