Hey,
I had this problem for YEARS.
Tried all the tips and tricks I found on the web and nothing helped. Cleaned/replaced Maf sensor, cleaned intercooler and throttle body, changed turbo inlet pipe and throttle body pipe, replaced crank sensor, used Lucas fuel additives, feed my FPR vacuum source to a different one, replace FPR etc etc. It's been so long and so much money has been spent i've lost track of the others ive tried.
What fixed it for me was when I had my tranny fluid flushed and replaced in January 2020 (due to a P1710 problem) and now it's permanently gone.
Hope this helps you
Cheers,
