Hey guys, so I just got my downpipes installed from a local shop I got these codes coming up is this normal or did they mess up in the install?

[Devildog0905]

Do you have a jb4?

[Snypa]

Only two codes normally come up after catless DP's. I'll check later and let you know.

Thanks

No I don't, I'm using MHD to check the codes... Note my Check Engine Light is on still because I don't have a Downpipe fix yet.

Alright sounds good... Thanks for the help.

Looks like to me they have the o2 sensor connectors mixed up

[chuiisatriani]

wrong place to put this unless you're trying to buy parts. if so, I have injectors, new Delphi coil packs, and a full car for parts

[whyzee125]

They messed it up. Probably mixed the o2 sensors up.

Hey guys I managed to clear two codes sorry for posting in wrong forum btw.. here are the other codes in getting if anyone can help.. the car feels like turning off when starting it up or stopped..

Have them check your 02 sensors. I had that happen to me twice, when I went to a guy on this forum who does DP installs for $150. First time, he did not plug in the 02 sensors all the way & those codes would come on every few days. The second time when I had the DP's uninstalled, he forgot to plug the 02 sensors on completely & the lamda probe and misfire codes came on. Plugged it back in & everything ran fine

Hmm I'm still getting the same codes.. I went under the car and unplugged them and connected them back in and the same codes come up... Maybe it's the tune (MHD) I will flash back to stock tomorrow.. The o2 senors look like they are in the correct place.. black wire on longest pipe (closest to the middle part of car) grey wire on shorter pipe (closests to the wheel) they systems I'm getting as well are stutters when starting up the car and my rpms go up a bit then few SEC's pass and my cars rpms go down the rpms don't go up really high but just a bit like somtimes my car burbles and pops. After that the car runs smooth.

I had these exact codes when I did my DP's, and it was because the precat (first set) of O2's were installed backwards.
Except I was only misfiring 3 cylinders and it happened randomly.

I don't quite understand... so what do I need to do? Which one is the precat 02? black or grey wire? I just flashed to stock I will check to see if i still get the codes... Thanks everyone for your input.

If you are coming from the exhaust manifold down the dp it would be the first set of o2's. (pre cat).
If you look at your codes it literally says reversed, read code 2C24.

I forgot which wires went to which pipe. From what I remember it is the black and gray wires they were reversed on my install. Which caused the same problems.
