2001 4x4 4.7 sr5. My idle is so low when stopping at lights it cuts off on occasion. Any ideas.:confused:
Basics to check:

  • MAF and Throttle Body Cleaning
  • Clean air filter and I also recommend going with a good foam filter wet or dry. I am running the True Flow intake and like it very much.
  • Good plugs
  • Regular oil changes with a quality filter (NOT Fram)
  • Regular doses of fuel injector cleaner. I clean mine with Lucas fuel injector cleaner about every 5,000 miles.
  • Clean fuel filter
  • Clean PCV valve
  • Any loose vacuum hoses
Do you have any CEL codes?
