Hey guys I need your help.. I just got stupid P29F3 code (LPFP sensor) and misfiring almost every single cyl.. Every time I go WOT injectors shut down I guess at 4K+ rpm I loose power and service engine light comes out. And after little while turns back to normal. (Yes I searched here) But I changed my spark plugs 15K miles ago (car has 47K miles) My question is if I only replace the LPFP sensor these wont happen again? Should I replace my spark plugs also due to misfiring? If you guys can help me I'd appreciated.
