I just purchased a 1999 Honda Prelude with 208k miles on it. I've already replaced the distributor, wiring, spark plugs, air filter and given it an oil change with filter as well. I am experiencing a rough idle with the A/C on and off while driving but not as much in park. Does anybody have any advice on what I should jump into next? I'm unsure of the last time the timing belt was changed and looked to do that as well as a compression test this week. I live in Orlando and do not know anybody here that does great work. Any advice would be greatly appreciated.

Thanks!

-edit I was also looking into doing some work on my block as well because I'm sure I will need to replace the rings. Does anybody have any advice on what the best rings/pistons and any other block accessories I could pick up in the process to make her run great, I plan on getting a turbo setup in the next 6 months and want to be prepared.
