Jalal Syed Posted August 5, 2014 Report Share Posted August 5, 2014 I have a r32 with a rb25det in it. I ran the car with the stock 25 ecu for two seasons. And now couple of weeks ago got the g4 put in as well as a tune with pretty descent numbers for a stock rb25(stock turbo). The car ran fine for 4 days, and then one day after the car sat for 5 hours at work, i went to start it and it barely revved up then just died. I tried again and it would try to keep idle, would hunt for couple of seconds then die again. started again and this time added some gas, my rpm was jumping all over the place at this point and the car was very rough. After keeping the car alive manually (adding some gas) after couple of mins it went back to its normal self...it idle was perfect and the car drove like a dream.Â The weird thing is it only happens when I leave the car out in the sun for more than 3 hours or so. When I leave the car parked in the garage in my house and start it the next day its fine. I can only seem to replicate this problem at work...Last time i started it after a 8 hour shift and i had to manually rev it for atleast 15 mins before the car settled down. The rpm gauge jumps everywhere and the car feels like its missing at random spots, my wideband numbers are all over the place too. I will try and make a video next time. I hooked up the laptop to it and only fault code is RPM limit activated, which i believe is caused by the jumping rpm gauge? The car has no vacuum leaks and is running copper plugs bcpr6es changed at last oil change. It runs and pulls fine otherwise.Â Quote Link to comment Share on other sites More sharing options...
