Default Mass state inspection... FAIL

so i have currently on my car an intake, uel headers, and axel back exhaust...

and i failed mass state inspection not for the exhaust, that was fine, but the "OBD readiness monitor" wasn't.......... ready i guess. and the reason is cuz me being me got a scan tool (not a cheap on either) and erased a code that i keep getting... cylinder 1234 misfire. how can i make it so that those codes dont come up and further more how do i get my car "ready"

btw its a 2002 Impreza 2.5TS, and i have gotten spark plugs, wires, headgaskets, timing belt, valve adjustment, battery, alternator, and full tune up and i still get the codes

thanks in advance guys

Also to reset the obd 2 drive monitor you need to drive like 300 miles of mixed highway and city driving after clearing the codes. At least thats what I was told when my moms car failed after I cleared the codes. That's why I got my car registered in Michigan, no inspection here. Yay college.

Your timing may be off if you have misfires.

Oh em gee, how many people actually read that it's a 2002? Tactrix doesn't work on anything older than 2005.

If it has misfires, fix the damned misfires. That's not something you want to dick around with.

EJ251 misfires are almost always ignition related when you don't have a lightweight flywheel. Change your plugs (use NGK coppers) and maybe your wires too. Odds are that will solve it.

Timing is perfect on the dot 10 degrees which the ideal is 10 +- 8 and I changed the spark plugs and wires to NGK like 8 months ago...

Ron was asking about the timing belt, not ignition timing. Has that been changed recently?

Misfires can be cause by a number of things, sounds like you've checked most of the easy ones. the only one i haven't heard yet was to check your Valve lash. Are you getting any other codes? I always have issues passing emissions, i have cams and a light weight flywheel so it's always battle. Here is the drive cycle you need to do to get all areas to be ready. I have yet to find a road where i can get this done in 12 mins but usually i just follow the basic idea and can get it in under 30 miles and it takes about 80 miles for my CEL to turn on. Also here in Utah we are allowed to have on area not ready and still pass. My cat and evap system sometimes take a while to go to ready so I'll drive around until one does and then hurry and get the test done.

Stored codes (code in memory, no CEL) usually won't fail you. Go go go!
