I have a 2009 lnf with 80k on it I recently added a few modds which are all from zzp 3.25 Intake, catless downpipe, catless and mufflerless exhaust. After all those my car started throwing p2101 and p2420 I replaced those sensors and they both blew again. Today I started the car perfectly fine tuned it off can cleared p101 then it misfired and blew all spark plugs I replaced them and it blew them again right away. Any idea on what it could be? Besides getting tuned I plan to soon I've just been saving the money

Well your fuel trims are probably all over the place, I suggest you get that tune as soon as possible, a p101 means you have a boost leak

Is there a way I can get the car back up and running or am I gonna have to have someone come street tune it? And what can I do to target the boost leak?

Is the car boosting to the normal psi or is it lower than before swapping parts? I would try putting the factory air intake back on until you are ready to be tuned. The exhaust shouldn't throw things off that much. I'm guessing you got the angled O2 bung for the rear sensor on your downpipe? If you lose your O2 sensors it will richen the fueling and make your plugs sooty. I would not be boosting it until you get it tuned with the issues you currently have just to be safe.

Also- use the factory spark plugs and don't mess with the gap on them.

The car isn't under boosting or over boosting however it takes a little longer to spool up, and yeah I do have the angled o2. My boys was just telling me it's most likely that my car is just sucking more fuel then air cause the o2 and maf are gone. But I'm going to AutoZone in a bit to get a o2, maf and plugs when I get home I'll swap the air box throw everything on pray and let you guys know, thanks for the help I appreciate it.

You have a boost leak don't waste your money on a new maf.

Ok so I put the stock air box back on replaced the maf, replaced my o2 after the cat that it throw a code for, and cleaned my spark plugs that i bought yesterday and now the car is running good sounding good although it's popping a little bit at idle like baby misfires, so I left the car running and unplugged each spark plug wire one by one and the car idle weird each one I unplugged so I'm thinking it's not a spark plug/wire problem. Anyways I'm stuck now

Are you running the stock intercooler? If so, have you checked to make sure it's not cracked?
