Cars interesting problems- need ideas

did you use all new gaskets on intake mani (between head and between the plastic upper), and the throttle bodies?

heaps of people will tell you sensors usually chuck a DTC when they're faulty. but if they are slightly out of spec then they wont set a DTC and you'll have to compare known good specs against yours to isolate the fault.

tuning adds another huge variable. my car has a throttle remap using the popular 'smooth throttle' map on the forum here. i have not reflashed or reverted my ecu to stock in an attempt to resolve my issue. i have my reasons but in a nutshell, the car ran fine with the software tweaks for a while before it started happening
