I had a gas leak on my 98 Chevy Malibu, it was fixed but now it don't run right.?

[Alba]

The guy replaced the whole fuel injector panel. The next day I went to drive it the check engine light come on and started flashing. The guy had a thing to see what was wrong and it said it was the cylinder 6 misfired. The guy put the other fuel injectors back on, changed the spark plugs, wires and the egr vavle. What could cause this? The guy is a mechanic. When I start it it idles really rough and makes a weird noise and shakes. When I push the gas it idles up and goes back down, but then starts going crazy and eventually dies. I cant drive it as the acceleration is not good at all and starts shaking and when I stop it dies. PLEASE help me.

Ask the guy who did the work to check the egr,they CAN be put on backwards whichs causes a vac leak at #6 cyclinder.Its easy to check by pulling 1 plug and 2 bolts.

A miss would not cause the check engine light to flash. You may have a bigger problem maybe a bad rod? What does the sound sound like?
