#19 of 20 Miss fire on front 3 on a 2003 by slewisomaha

2003 v6 with 105,000 miles running rough at idle. figured it was a misfire & it was on 2, 4, 6 (the back 3) full diagnostic was done at the shop & replaced the wires & plugs. It's still running rough on 1, 3, 5 the hour after the plugs & wires are done. just spent $300 on that service. Any ideas on what would cause this jumping of misfire from side to side?

does that car have coil packs or distributor cap + rotor? my 1st guess would be fuel injector problem or cap+rotor issues... misfire due to plugs usually doesn't occur on so many bat once... did you have all plugs changed? what brand of plugs in the car?
