I have the same codes as OP and a cat-back exhaust.
I didn't lift the car up yet to check out whether the O2 sensor wires were being shorted.
Sure enough the emissions fuse was popped.

I went ahead and replaced the fuse. The car had a really hard time idling and would stall and still had CEL.
Only way to keep it alive was give it gas.
Pulled the fuse and it was still intact.

Any suggestions?

I only have exh too I don't see anything for emissions. I checked this fuse and it was fine. I don't see anything wrong with the wires by the oil filter. I'm only getting the 102 and 443 codes. My 420 code disappeared though lol. The dealer recently replaced my clutch and flywheel. think maybe they did something? I don't know what else to do. But I was wondering if maybe its a maf issue? Cause my scan gauge doesnt display engine load anymore it stays at 0

I have not done anything to the car. I got these after I got it back from dealer. I just didnt know I had the codes cause I hadn't checked the codes til one day I randomly decided to check to make sure the cel was just the 420 code and then came to discover this. Also a few days ago I was runnin thru the gears and when I was in 4th going wot the engine like lugged big time. I found a big leak in the vacuum so I hope that's why it did that. It felt like fuel cut off or something then coming back on

I found this. Think this is my problem? The dealer did this to the wires. They lead to a wires intersection right under the oil filter.

Thanks for the pics. Those bare wires might be shorting out somewhere.
I'll have to check that area for sure. Still trying to diagnose these codes as well.

Going to end up bringing it to the dealer, because this is a big headache for me already.

This is kinda wierd and don't know if it relates but about a month ago, I woke up went outside and turned on my car to get it warmed up before leaving to work. I drive half way down the block only to notice I have a flat tire. I back it up into the drive way jack it up and put the spare on it. Turn it on to head off to work and my check engine light is on, I figure I'll just have them look at it when I get to work. The tech throws 4 new tires on it and as soon as I start it no engine light. It just seemed wierd to me that it would turn on for something like that.

idle issues

i have a check engine light on for running too lean. i just got an aluminum flywheel installed recently and when coming to a stop the rpm's bounce between 1100 and 500 then go to the normal idle at 800. but other times it will bounce then stall altogether.
is the stalling and idle bouncing do to the aluminum flywheel or is it because of it running to lean?

P0103 is the code. Mass air flow sensor above yada yada yada....

What does this mean and what could cause it? It started yesterday.
*note* dont know if this matters but the day before it came on I switched from a 2.5" to 3" DP and catback.

ALSO!! P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating -PCM
This code has been coming and going for about a month. It makes my cel go on...then a day or so later it will go away....then a few days later it will be back.
