Help. Still have rough idle once car warms up. Car starts great and idles well during high idle. Once it warms up the idle is poopy-too slow. Idle picks up when high speed fans come on - good. When they kick out, idle too slow again.
My tech checked for vacuum leaks (so did I)-passed.
No CEL light.
EGR valve and solonoid-passed.
Changed PCV and checked lines to and from.
Cleaned IAC - seemed to help a little.
Gas mileage - Brutal.
Changed fuel filter, plugs, wires, coil and air filter.
What am I MISSING?
