ok, here's my problem. I have a 1999 3.8 M5 and I've noticed that the car is severaly lacking in power, no matter what gear I'm in. Also, if I try to pass a car and press on the gas hard, the car bogs down and starts to jerk severely. If I get to speed slow and gradual, all seems to be fine. Any ideas?

Re: Power Problem
The bogging down could be an o2 sensor or a clogged cat but the jerking could be a bad vaccum leak. Do you have a SES light? Maybe could get the car scanned. Could have EGR going bad too. Theres alot of possibilitys.Originally posted by kala

Re: Power Problem
Thanks for the reply, I'm gonna pull the plugs and check them. I'm also gonna get a buddy to help me try to isolate the vacuum leak. It may be the cat too, it was making that horrible noise last week but has since stopped, it may be plugged solid too.....Stephane<br />1999 Camaro m5 Black/Red<br />1999 GSX-R 750 Black/RedComment

Re: Power Problem
Did you get anywhere with looking for a vacuum leak? When I look for a vacuum leak I like to use a can of carb/ckoke cleaner. Once you hiy the leak it will purr so nice for a few seconds.Originally posted by kala

Re: Power Problem

Re: Power Problem
Hey crushed......turns out it was the cat....took awhile for the SES light to come on but once it did, the problem was easy to isolate. I had checked the plugs, coil pack, wires, all looked good. thanks for the help.Stephane<br />1999 Camaro m5 Black/Red<br />1999 GSX-R 750 Black/RedComment

Re: Power Problem
i was gonna say... thats the exact thing that happened to my car... it ended up being the cat, im glad you didnt go through the hell of replacing half the crap on your car to try and figure it out, much like i did2000 Camaro 3800 A4Comment

Re: Power Problem
The funny thing is, it took quite awhile before the SES light came on, I was getting worried. and you're right, I would have replaced a whole bunch of stuff for nothing. It's bad enough they tried to sell me a new cat for $857 too. I had to get the part myself and they're installing it.Stephane<br />1999 Camaro m5 Black/Red<br />1999 GSX-R 750 Black/RedComment
