Fiesta rs turbo started running lean
Hi guys and girls, iv had the fez for 8 years ands it been fine but a few months back just started running lean and had a few ideas from people but nothing is working i had a 195 chip and injectors removed all back to standard but still lean. Also sprayed brake cleaner to find air leaks. Anyone had this or have any ideas what i would be? very gratefully to any help thank Dan.
