Was wondering if the afm's are both the same or they are different? Had problems with car dropping rev's & wanting to stall.. I looked at pins on afm's & one has 4 pins, the other 5 pins leading out of afm's... Done the usual cleaning of afm's with spray, changed fuel filter & fuel pump, swapped over the coils as well.. Ran good for abit but now back to dropping ...
