Swampy442 Posted November 5, 2015 Share Posted November 5, 2015 (edited) Im finally out of ideas. Im recommissioning the Do luck Aristo and getting it back on the road after a few years in bits. It starts on the button, idles smoothly moves forwards and backwards under its own power, so almost all good. Problem is the idle is really rich, the AFR gauge is indicating around the 10 mark. Initial fire up the AFRs will rise to about 15, then drop down to 11s, then settle at 10/10.1 Ive not driven it anywhere yet, but Ive got it nice and warm and the results are still the same. Spec :- 2JZ GTE, stock ECU*, stock injectors*, Precision turbo, Aeromotive FPR set to around 2 bar static pressure, Walbro pump. *I know Im a hippocrite lol but this is just to get it running and leak checked, Ive got Denso 800s and an Fcon pro gold to go in. Im about to try a new O2 sensor, trying to get an IACV, any other suggestions?

Style Posted November 5, 2015 Share Posted November 5, 2015 ECU water temp sensor? If it's gone, ECU will think the car's cold all the time and run rich. Or is an AFR of 10.x too rich even for warm up? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted November 5, 2015 Author Share Posted November 5, 2015 Thats my point mate, maybe for the initial start but should rise up to 12 or so if I remember. Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted November 5, 2015 Share Posted November 5, 2015 Do you not have to recalibrate the afr meter with clean air? Quote Link to comment Share on other sites More sharing options...
