Help!!! Acceleration lag or bog problems with 98 Boxster

[cbarnes]

I have a 98 boxster and had the check engine light come on. Was told I needed a new passenger side cat. so, instead of paying $900 or more for one. I decided to buy two new cats from Fabspeed. After in stall the check engine light came off. I had a lag in acceleration before I replaced the pipes and after. It mainly does it when in automatic mode. When I use the tiptronic it seems to not do it. Does anyone have any idea of what could be causing this or what it could be???

Also, I have a problem with my spark plugs seals or rings leaking. I replace plugs, seals, and o-rings and cleaned everything up nicely. Now its still leaking and a little more than before. I assume its because of being cleaned.

Any advice or help would be greatly appreciated.

Thanks in advance.
