Catalytic Convertors

[donald.grayjr]

Does anyone have a good and well priced site for ordering aftermarket BMW parts? I have 98 740iL that is needing convertors. Thanks.

Are you sure your cat's are bad?

Well, now we're not sure. My wife called some other places and they questioned some toher symptoms. Like the fact that the car has continuous power on hills. And the fact that the car has only pooped out twice and the quickly recovers. And the two times it has happened is when my wife hammers down to enter the highway. Other wise the car is fine. Im not trusting this shop right now because it was just in there for a 21 point inspection and they didn't catch this. I would take any advice at this point.

I am currently deployed to Kuwait so I can't be there to help her. Thanks.

It'd be worth while to make sure the O2 sensors are good.

[donald.grayjr]

Yeah, me and another bud were talking about that. Would a scan pick that up? Or is there a specific test that needs to be done. I know she's had it on the computer a couple of times and it didn't pick those up.

[witeshark]

I think a scan should pick that issue up. But I think it's possible to simply inspect them.

Diagnostics will deffo pick up a bad o2 sensor.

hi guys probably a dumm idea but it's a 12 year old car why replace them they are expensive and as we have seen most pollotion is from the goverment not our cars...sorry had to throw that in ..if you don't have yearly insections in your state why not replace it with a straight pipe to replace the cat? it is cheeper safer and easy to replace if demanded by you epa gestopo....i'v done it to mine with no ill efects,and it sounds better..
