Ecosteve Posted July 4, 2018 Share Posted July 4, 2018 Hey folks, My supra 2jz-gte manual has a habit of stalling when approaching junctions. Its not every time, 1 in 10 maybe. Its perfect when cold, also idle is around 500rpm when hot, which seems low to me. Cars done this for 4 years with the previous owner, but its driving me crazy, changed all vac lines and the ICV. This did help a lot but still 1 in 10 stops the revs drop and stall. My plan is to check tps and raise idle tomorrow, any other things i should look for while im at it? Thanks for the help Quote Link to comment Share on other sites More sharing options...
Ecosteve Posted July 5, 2018 Author Share Posted July 5, 2018 Well i increased idle from 500 to 800. So far it seems quite happy now. Will test further Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 5, 2018 Share Posted July 5, 2018 VVTI? Has it got a BOV? Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 5, 2018 Share Posted July 5, 2018 500 is too low, the book for a GTE says 650 + or - 50 rpm Page SS-9 http://www.mkivsupra.net/vbb/content.php?77-Service-Specifications Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted July 5, 2018 Share Posted July 5, 2018 Throttle body stop screw? They shouldnt be adjusted, they are factory set, adjusting those is just hiding a problem Quote Link to comment Share on other sites More sharing options...

Ecosteve Posted July 7, 2018 Author Share Posted July 7, 2018 I raised the throttle stop screw. It had unscrewed itself. Il check the power steering Monday when im home . Its non vvti. It does have a bov, il try blanking it to test if that's the issue Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 7, 2018 Share Posted July 7, 2018 BOVs are only an issue on VVTI cars, dont affect non VVTI cars, although they do sound shit Quote Link to comment Share on other sites More sharing options...
