lysaer Posted May 29, 2018 Report Share Posted May 29, 2018 Hi all Car is running fine except when I turn on the A/C it drops revs and has a tendency to stall either while idle or coming to a stop any input would be greatly appreciated, I have attached a copy of my latest PCLR and can take a log if needed Thank in advance all r33_gtr_march_2018_oil_pressure_enabled.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 29, 2018 Report Share Posted May 29, 2018 You have zeros in your AC Step table, this table determines how much extra the idle valve opens when AC is on. Try putting about 5% in all of these cells. lysaer 1 Quote Link to comment Share on other sites More sharing options...

Try putting about 5% in all of these cells. So I have been testing with different variables the last few days started at 5% then 6% up to 10% but still getting stalling when coming to a stop I stuck in 25% just to test it at standing idle and as soon as I turn on the AC it just dies. Wasn't sure how much over 10% I should go for driving or if there is somewhere else I should be looking at resolving this Thanks again in advance Quote Link to comment Share on other sites More sharing options...

Something doesnt sound right there, I would have expected RPM to increase with that much, maybe your idle control isnt even working. Can you do a short PC log of a few minutes of running/idling, switching AC on/off etc. https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...
