checkcoil pack No.1 (Front Drivers Side)
It's the easiest to get to.
Take it out remove the rubber cap and check for cracks/breakage.
as per Damaged Coilpack

 

What about the other three.

 

if you reapir the broken coil packs can they be used again eg if you glue or use a soldering gun to restick them together will they be ok to use again ?

 

no....genrally they are providing a weak spark.
this is an extreme failure in the picture linekd above.
Some just have hairline cracks, others no sign of cracks but still only give a weak spark.

They are 11-14 years old now and are exposed to extreme heat and cold.

 

Quick nerd point Jasma on your exhaust is not who made it but a standard of manufacture.

Plugs,coilpacks MAF are the normal answers.
