So I'm putting my stock downpipes back on (selling my Titek 3" dps btw) for service and upon completion I start the car, sounds nice n quiet for 5-10 secs til the rpms drop to about 600 and the car starts shaking and vibrating,. After ~ 10secs of this it smooths itself out..

Turn car off and restart, same thing and service engine light comes on..

My question is, does the autoclear have to be disabled ( enabled for catless dps) to run properly?

Or did I just somehow cross my 02 sensors?
Id like to know for sure before I have to get under the car again and start messin w/stuff =\

For the record I swapped dps in a whopping 2hrs compared to my first try of 7hrs =)

Thanks for your help!

I would check codes before we start to assume anything. Sounds more like HPFP but could also be you swapping the O2 sensors.

HI
I would check the O2 sensors. Same thing happened to me after a friend reinstall my cats 2 weeks ago. The car was shaking like crazy. My mechanics found out that the O2 sensor where mounted wrong. Autoclear wont help, you need to mount them correctly
