Default Cyl. 4,5,6 Misfiring.... How come???

had timing redone after it was done improperly. After that i replaced the coil pack and plugs. DID NOT REPLACE WIRES. The car is throwing Misfire codes on 4,5 and 6. What could this possibly be?

I was first told that it is most likely the wires... and then told again by a few people that maybe the valves.

sounds like your driver's side cam is still off by a tooth or two

Default All plugs are properly gapped and torqued. Car was re-timed and was dead on.

I am going to get new wires later on this week and go from there.

Default Did you release the cam gears from the camshafts?

The belt has to be tensioned manually before you set the torque on the camshaft bolts. The cam gears should be floating which allows for the belt length between the gears to be tensioned like the rest of the belt.

That won't cause a misfire though, being off a tooth or 2...

I disagree, one cam off timing can definately cause misfires

Default This is true

I did a cam adjuster on a Passat 30V back when I worked for VW and one of the cams was one tooth off...the car would misfire at idle but as soon as you stepped on the gas it went away.

Default My car misses at idle and...

it sounds like a spark knock or a lifter tick. It gets louder as you step on the gas.
