My 1998 chevy lumina got multiple error code ( P0305, p0135, and p0442) after repair a horn from a dealer. After repair I only have run 1000mile. What could be the reason for this? Thanks for your help!

Nothing to do with there repair
305 is a cylinder 5 missfire. 135 is an o2 heater code. 442 is an evap leak.
This would have occured even if you did not have the horn repaired.

Repair shop pulled out one firing line and disconnected two plug lines of V6 plug. After I check out the problem and reconnected them. And codes were gone. They wanted to make big money. I understand it.
