Idk if anyone seen the thread I made but I'm having a misfire issue.
Pulled the codes and got this
P0303 cylinder 3 misfire detected
P1399 manufacturing control. Ignition system or misfire.
Now when I cleared the codes I drive the car no check engine light under normal driving. I put it in 3rd gear and punched it and the car sputters and the cel flashed again. I tried punching it in 1st & 2nd but the car didn't sputter. It seems like this happens when the engine is under heavy load.
Compression was fine.
I got new plugs but haven't put then in yet it's snowing really heavy.
Here's the old plugs
Ill see what happens.
