Jokers: how long have you had the lightweight flywheel in for? Everyone has been saying its mine as well but it's been in for 20k. Also what brand?

i have changed back to the stock flywheel and have a lightened crank pulley

i still get the misfire codes?
my idle still dips and with the heavier flywheel it sure shakes heavy until it catches itself?

btw i have a hybrid build, it idles around 850-950

I know I post this in most misfire threads haha, but do you have your EGT Sensor still? If so do the resistor mod to it and report back. If it's on it's way out it can tell the ecu false misfiring.

Anything that is lightened can cause misfires. As mentioned I would ditch the lightweight pulley. Did you replace the stock flywheel yourself? Was it hard?

The lightweight items will cause a misfire in ALL cylinders, not just one. Likely you have a bad injector, coil or plug.

That being said, I have never seen a EJ engine have misfire issues from just a lightweight pulley. Flywheel sure, if it is super lightweight, but not only the pulley.

Default simmilar issue, any help grateful, log attached

https://drive.google.com/file/d/0B_2...ew?usp=sharing

very simmilar issue, just replaced timing belt and started up to find missfires on all 4 cylinders, cracked back into it and realized the lines on the new belt did not match up (was very much rushing on first install) reinstalled and bingo, perfect, ran great and no issues, no cels after many hundred miles. now out of nowhere these codes : P0000 PASS CODE (NO DTC DETECTED) false true
P0000 PASS CODE (NO DTC DETECTED) false true
P0301 MISFIRE CYLINDER 1 false true
P0303 MISFIRE CYLINDER 3 false true
.... does the log look ok, it looked fine to me, and what would cause these codes... im pretty confident its not the timing belt after i reinstalled it everything was lined up and on its proper teeth, could it have jumped teeth? thanks, hope this might help with op issue, i would guess cams jumped teeth,, think mine did the same... im gonna tear back into it and check as well the sensors but i cant understand why the codes would take so long to appear
