FS: Used N54 injectors and Coil Pack

First Aid Kid · 04-18-2016, 02:53 PM

Initially swapped out my injectors and coil pack when my car was getting misfire. With the worst possible luck, I am still experiencing misfire after changing to new ones so these might not be faulty at all. Too late so these are no use for me anymore so I am selling them.

Injectors - Index 7
SOLD

Coil Pack - Bosch 221 504 470
SOLD

Located in Richmond Hill, ON.

I was having a similar issue, replaced the spark plugs and misfires persisted. Took it to the shop, there was a leak in my valve cover gasket. Replaced it, fixed the misfires significantly. They weren't actually misfires at that point, it was a drop in RPM on idle which felt like a misfire as it would drop and come back to normal. Finally decided to change the Coils as well and no more issues after that.

So to summarize, make sure they're misfires and not just a drop in RPM that feels like a misfire. The differential diagnosis for that is very wide. Luckily for me it was the valve cover gasket and fixing it solved the problem.

Good luck.

My valve cover actually cracked (not just the gasket) and I had it replaced already...... poor me
