This is a semi-common issue as ive seen several forum posts of mostly higher milage G70s & Stingers (sometimes low milage too) having the same problems, and it seems that no one has posted the fix.
For the last year or so i have been struggling to find answers on what has been going on with my 22 G70 3.3 AWD Sport Prestige with 95k miles. The car would run perfectly 90% of the time (other than a weird high idle around 1000 rpm), and then randomly go into limp mode and throw a bunch of CEL (most often p0302, p0603, p00aa, and paa00). When this would happen, the car would have no power/make no boost, shift poorly, and barely idle misfiring very badly and sometimes even stalling.
I tried changing spark plugs, new ignition coils, cleaning injectors, looking for vacuum leaks, cleaning carbon from the intake and valves, and completly removing my JB4. Nothing worked. Last month I found a post on a Kia Stinger forum (same drive train) of someone with the exact same problems, so I reached out and he got back to me a few weeks later. The problem that has been haunting many G70 and Stinger owners alike is a $60 VVT Solenoid. It looks like they tend to go bad some time between 70k-100k l, but they dont throw a code for VVT or cam position, just random cylinder misfire, AFR imbalance, among other codes. I replaced the bad side (the other is still on order) and have had 0 problems in over 2000 miles. High idle is fixed, no misfire, no AFR imbalance, and no limp mode. Below is the link to the part you need. I hope this helps others in the same position.
