Notts_TT Posted October 10, 2011 Share Posted October 10, 2011 You may of seen a previous post with vid of my supra running rough and kicking black smoke out. After a week of changing plugs and hunting for a solution I found the problem, the hose running from the map sensor to the t piece for the boost gauge was off, I plugged it back in and it stopped smoking, still idling a tad rough but I'm happier than before It hasn't been on a run out for a year so I'm sure a good run will sort that, plus plugs are fouled due to over fuelling so that won't help idle will it ??? Thanks and the search button is my new best friend.... Link to comment Share on other sites More sharing options...
hodge Posted October 10, 2011 Share Posted October 10, 2011 Reset the ECU and take it for a run and all will be fine. Link to comment Share on other sites More sharing options...

TheTurtleshead Posted October 10, 2011 Share Posted October 10, 2011 I would T that off somewhere else mate. Maybe the Blow off valve pipe on the back of the manifold where I have mine. Its best not to interfere with the pressure the Map sensor sees, as this could affect your running Link to comment Share on other sites More sharing options...

Jellybean Posted July 22, 2012 Share Posted July 22, 2012 Hey I got the same problem towards the end of the track day; to get home I bypassed the vacuum line from the map sensor goes between the intake and cam cover , loops down into a metal pipe which splits into two vacuum pipes near the rear firewall Not too sure what they are for as she seems to run ok without it connected Is it an intake off to get at the vacuum pipes, can touch them with my fingers but cannot feel any tears or loose Link to comment Share on other sites More sharing options...
