I still have my used bank 2 cat and 6 months ago I got quoted from RRcats $390 to sell which tbh isn't bad but I stubbornly decided to wait to see if the price would get any higher. And now even with the price boost activated (that wasn't activated the first time I got quoted) on their website...

I promised to document my oxygen sensor behavior so here you go. About three months ago or so i changed my precatalytic oxygen sensors (140k on them). It was followed by VCG change and oil change. After oil change my BCG started leaking oil right on top of oxygen sensor 1 bank 2. O figured it...

I'm fairly certain my 2004 330Ci cats are completely stopped up. Bad loss of power, extreme fluctuation of O2 Sensor 2 data when applying any throttle at all, and the engine completely shuts down when I give it any more than half throttle - almost like the computer just shuts down and the manual...

Hi guys, My catalytic converter was recently stolen and my car has been off-road for a couple of months while my mechanic has been trying to find a used one to weld on. Unfortunately, he's not been able to find a used one and is now offering to replace it with a straight pipe. He reckons that...

Hey all, I've got a 2005 330Ci that I've painstakingly fixed up quite a lot. Had a small issue with a vacuum leak that ended up just being a faulty MAF. Replaced it, got rid of P0174 and P0171. Now the engine is completely vacuum tight and equipped with all kinds of goodies. Unfortunately, now...

I have a 2003 325i and need a new front/rear (1-6) CC (not a NY or Cali) Any advice on brand to purchase that is reasonably priced? Online I see prices high and low but am told some are poor quality. Thanks!

I started to post about this about a week ago but found a page that had a check and fix... Here's the scenario. 2003 BMW 325i 248k miles. The engine would idle fine - super smooth and quiet. If you push the pedal hard, it would go into limp mode. If you got about 3500 RPMs it would go into...

Hi all, I got some great info from previous posts on this topic, but I haven't been able to crack my problem yet. I'm hoping you all can help. 2002 M3 w/ 68K miles. CEL intermittently comes on, throwing the P0420 and/or P0430 codes. Also the "Rich to Lean sensor threshold voltage" is failing...

Hey, I looked around and couldn't find great advice for my situation. My 03' 330ci has an issue with the catalytic converters. Sometimes the CEL comes on, and I've had the codes read, efficiency banks 1 and 2 I believe. Other times, it stays off. It goes on and off every few weeks. I'm in...
