Glanza_Mike Posted April 10, 2017 Author Share Posted April 10, 2017 Alright J cheers mate, I've took the inlet manifold off yesterday to clean it up and spray. I noticed my cam sensor connecter was soaked in oil from my recent cam gasket leak, I'll also clean the throttle which was all carbon'd up so I'll post in a few days about results.

Glanza_Mike Posted April 13, 2017 Author Share Posted April 13, 2017 Good news! I sorted it! And funny enough it was none of the things that anyone suggested Haha bloody cars! So my air filter sat quite close and in line with the rad fan, and it was sucking up all the air the fan was forcing onto it which was causing the maf some troubles. Moved the filter and it's mint Quote Link to comment Share on other sites More sharing options...
girth45 Posted April 13, 2017 Share Posted April 13, 2017 Interesting to know , well done sorting it and passing on rhe info Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted April 13, 2017 Share Posted April 13, 2017 Curious issue and the reason most wouldn't pick up on it is you are still using the stock ecu, a standalone would have been mapped to suit. Maybe consider building a heatshield or air box for it Quote Link to comment Share on other sites More sharing options...

My VVTI solenoid had failed. new one fitted and problem solved. Just started getting similar problems. Anybody know the part number for the VVTi solenoid? Also any guides on removing old and fitting new one? Thanks Quote Link to comment Share on other sites More sharing options...

Matt recorded the swap here - http://www.mkivsupra.net/vbb/showthread.php?329236-Cleaning-my-Oil-Control-Valve-(OCV)-on-a-VVTI-Supra Not sure. I just saw the post I quoted above which said vvti solenoid. Is it the same thing? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 17, 2018 Share Posted December 17, 2018 Just a bit of input, but if you do narrow it down to the VVTI solenoid, inside the oil feed is a micro mesh filter, its a service item and if thats clogged it may give you issues.

Hi swampy, is the solenoid the same as the oil control valve as posted above? Also is the micro mesh filter bit a separate part which needs to be ordered or just cleaned?

Chris Wilson Posted December 18, 2018 Share Posted December 18, 2018 It will blow clean with an air line. I have a perfect used solenoid and actuator if you or anyone else needs either. Quote Link to comment Share on other sites More sharing options...
