You either have a bad plug wire or have cracked one of the new plugs while installing them. Try watching under the hood while someone else accelerates the engine to locate the noise.
Good luck dont forget to rate.

check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.

I too have the same problem on my 2005 1.8t B6. I noticed a hole in the breather hose coming off the valve cover that runs to another port under the intake manifold. I have the hoses on order and should be here on Wednesday. I'll post again if that fixes my problem.

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.
