Hello, I realize this post is old but I have the exact problem described mine is a JZZ30.
"Ok so i finally got my 1j running was running good for couple days then had slight misfire so i decided to put new plugs in her.After putting the new plugs in she was running great so good i as confident enough for her first road test got about 30 feet from my house and she wouldnt go above 2 grand and had the worst misfire ever. So i trouble shooted for about a hour im stumped i let her cool down and she idles around 900 and u give her gas and she sputter and backfires still missing also...."
I have already replaced the fuel filter and spark plugs and some of the cap in the ECU waiting on 3 to arrive and checked the timing and will do the fuel pump this weekend. What is the "ignitor noise filter" and how would you test if it working?
Mine will start and and rev if throttled slowly but if you punch it the misfire happens. My test drive was the same as mentioned "road test got about 30 feet from my house and she wouldnt go above 2 grand and had the worst misfire ever"
hope someone can help, I hate driving a commodore LOL!!!
