Diagnostic help...

[$chlitz]

So the other day I'm driving to work when all of a sudden the car loses power, feels like it wants to dies but doesn't. I managed to limp it the 15 minutes to work, but it felt very, very wrong. Parked the car, restarted it and it seemed like it was running mostly okay again. Scanned it with INPA and here are the results:

I've been chasing the 227/228 errors for some time now, my understanding is that they are generally vacuum related. Obviously the misfire errors are what really caused the car to run poorly. Question is, what caused them? I have recently replaced the oil separator/CCV system, rubber intake elbow, exhaust cam position sensor, DISA valve assembly, VANOS seals/rings, valve cover gasket, spark plugs, cleaned a stuck ICV, cleaned throttle body...just wondering it anyone can point me in a general direction to diagnose the misfires. For some time now the car has idled rough while in park after first starting up, but once I shift into drive it seems to smooth out. Like I said, I've been chasing the 227/228 errors for a while, so I always just attributed it to that. My diagnostic experience is limited to pulling codes with INPA so far, but I also have Carsoft...should I try to pull codes with Carsoft since it seems like it tends to give a bit more information? Any help here is appreciated...need to get back on the road ASAP! THANKS!!!

Misfire could be from a bad coil to a bad spark plug to a bad injector to a lean condition. You need to perform some test such as swapping out the plug and coil to another cylinder and see if the misfire travel to the other cylinder. Lean condition are a little harder to find since any vacuum leak could be the cause of a lean condition.

At least you know how to use INPA so you're a head of most X owners that just post here my truck isn't running right HELP.

haha...I wouldn't exactly say I "know how to use INPA"...I know how to pull and clear codes, but that's about it. Haven't had the guts to really delve any deeper yet.

Car has 95k miles on stock coils (i'm guessing) so I'm going to start with the coils. I read that if you're around 100k on stock coils, it's not a bad idea to replace them. Plugs have less than 5k on them, but I'll at least pull them anyhow and take a look.

Additional input form anyone is very much appreciated!

Also check the back pressure from the cat. Remove 02/lamba sensor and install pressure gauge. I'm not sure the exact but normal back pressure is around 5-10 psi....you want to see if you have a partial clogged cat converter.
