Hey guys. I had my car tuned recently for my long tubes. I had the tuner remove the cats, and rear 02's. he also removed the AIR/SMOG and carbon canister codes. The car ran good for a few hours. Now it runs like total ****. It WREAKS like gas, and is physically spitting gas and water out of the exhaust.

I took it to auto-zone and scanned for codes. The codes that came up were for low resistance on the 02 sensors.

Could this be related to the tune? Or is this something that I can fix by tightening a bolt or something. Any help is appreciated.

I wonder if the tuner tuned the car to rich which in returned fried the 02's? Was it dyno tuned? What did the wide band read?

did you put your longtubes in recently ? it's common for the coating to fry o2's. same thing happened to mine.

It did, but I sold it about a year ago.

It was not dyno tuned, it was mail order through madtuner.com. I had the car tuned about 2 years ago for just the performance shifting and high octane gas. Forgive me for being a total retard, but what is a wideband?

I did the long tubes in October 2007. The car had some misfiring issues, so I had it taken in to get fixed. The car just got brand new 02's and extensions, literally 1 day before the car was tuned.

The weird thing is, the car ran awesome after I picked it up from the shop. It continued to run fine until I had it tuned. I only needed to get a tune for the long tubes so I would stop guzzling gas. The headers are Pacesetter Longtubes, without the EGR and AIR stuff.

I sent the tuner an email to see if I could get it re-tuned to see if there is some issue with the tuning.

Wideband tells you the air fuel ratio, I would say its the tune. I agree with Schweet97z.

I would doubt it was something that madz did wrong, although theres always that chance. Where did you pickup those new O2s you were talking about?

Dunno. They were bought and installed by a shop.

There are 3 things that can cause 02's to get funky. The car being to rich, to lean, or ive heard of the coating ruining them also. If they are Bosch brand 02's get them out of there and replace them with AC Delco's. Im not sayin MadZ isnt a good tuner, just simply stating there is room for error with a mail order.
