Misfires
#17
Basically, if your car is stock, run stock plugs. If your car is flashed (or more), run the plugs your tuner recommends.

It was suggested by my tuner to run a colder plug after flashing (and getting misfires). Even if not 100% necessary now, with a few more mods I would definitely need them. From what I understand a colder plug cannot hurt your engine, but not running a colder one when you should can hurt your engine.

There is always the exception to the rule.
Run a cold plug and don't get it into its heat range and it will foul up, make carbon and cause very poor starting, poor slow running/idle and high power misfires.
You have got to get the correct heat range for your individual application.
But yes, if you have a heavily modded car its best to have a cooler plug as they will self clean. So long as you dont drive like your Granny.lol

I ended up getting new stock plugs and coil packs installed and the car now runs great. What an amazing difference. I'm now holding 1.3bar easily and the car feels like new. It's also idling and running smoother overall.
