Vacuum leak would make it idle high. Sounds like the throttle body has to be cleaned. Also try some injector cleaner in the tank. More than 1 bottle at a time... 2 or 3 per full tank. Not a fan of these, but they will help a bit.

It will start when cold, and after driving and then parking, the starter will not turn over? Replace your starter/solenoid.

WARNING: WHEN SERVICING THE STARTER MOTOR (11002) OR PERFORMING OTHER ENGINE COMPARTMENT WORK NEAR THE STARTER MOTOR (11001) , BE AWARE THAT THE HEAVY GAUGE BATTERY INPUT LEAD AT THE STARTER SOLENOID (11390) IS "ELECTRICALLY HOT" AT ALL TIMES.

  10. Remove the protective service valve cap and connect the Multiport Fuel Injection (MFI) Fuel Pressure Gauge T80L-9974-B to the fuel pressure service valve, located on the fuel injector rail. Slowly open the valve and relieve the fuel system pressure. Remove the gauge and install the protective service valve cap.
  11. Remove the safety clips and disconnect the fuel line couplings using disconnect tools D87L-9280-A (for 3/8-inch lines) and D87L-9280-B (for 1/2 inch lines). Install protective caps and position the fuel lines out of the way.

You may have loaded a fuel line or connector up with contaminants. What else is happening during the second or 3rd day of running? Is it running low on fuel? Try to make a list of your gauge set! It only makes sense.

Sounds like the alternator is going out the slow way.
Youre kinda lucky because almoat all alternators go out without warning.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.
