I have a 2003 Silverado with a 5.3L V8. It has been idling rough on cold starts and keeps throwing a check engine light saying it is running lean. I changed the fuel filter and ran lucas fuel system cleaner through it but the light remains. Is anyone here a professional mechanic who is good at diagnosing things and could help me out without costing me an arm and a leg?
Thanks in advance
