spangleR Posted January 27, 2015 Share Posted January 27, 2015 For some reason after putting my new motor in with my old intake/TVIS setup the TVIS butterflies seem to just sit open down low and feel like they shut up high (car runs out of go at around 4k, starts sounding really rich and starved of air). WIth the car sitting there idling they sit open on the spring and the breather side of the vsv is sucking air.Have swapped out the whole system for another lot and still have the same problem. starting to think its an ecu/wiring problem :/ I'm in Christchurch if anyones keen to have a look :DD Quote Link to comment Share on other sites More sharing options...
HighLUX Posted January 27, 2015 Share Posted January 27, 2015 Have you bridged the pins in the diagnostic port and seen if any fault codes come up? or have a look through one of these and check out the vacuum diagrams or trouble shooting http://www.cygnusx1.net/Supra/Library/TSRM/MK2/default.aspx http://www.cygnusx1.net/Supra/Library/TSRM/MK3/default.aspx 1 Quote Link to comment Share on other sites More sharing options...
spangleR Posted January 27, 2015 Author Share Posted January 27, 2015 Everything is hooked up according to the diagrams. Can't really check fault codes as the ecu is on its own wiring set up so have no check engine light. Quote Link to comment Share on other sites More sharing options...
HighLUX Posted January 27, 2015 Share Posted January 27, 2015 Easy enough to add a check light off the ecu plug and could point you in the right direction of what the problem is Quote Link to comment Share on other sites More sharing options...
