I brought a 2001 250gt about a month ago, didn't have as much power as i thought it would and after running a full tank through it i found it had really rubbish fuel economy, striped the plenum and swirl valves and cleaned them, cacked with buildup, and has been running like gold ever since, the change was drastic. i wounder how many people have rubbished these cars simply because no one ever maintained them properly.

after a week i went back in and stripped the plenum again to see if any further buildup/ oil had collected (i like making my life hard) there was more oil in the bottom chamber and i decided i hadnt done it well enough the first time so decided to polish it all up and put in some iridiums while i was at it, got a great finish this time.

what are the benefits, repercussions of doing this scotty? i have thought of doing this myself however i read that they were used to disrupt the airflow at low revs to enable better burning of the fuel, is this correct?

Hi guys. I know this is an old thread an not even sure if any of you are still around, however i wanted to thank you all for your input and comments, i brought a 2001 250gt with 130k on the clock and was surprised/ disappointed at the lack of performance and terrible fuel economy i was getting from it, i did some searching and came across this golden thread, i decided to tackle this project myself and started the tear down, scared myself shitless when i started it up the first time as i had left a vacuum hose off!, put it all back together and she is purring like new. thanks again guys (and girls if any?!) you have all saves me much pissing around and money.
