It just it 100k as well... I guess something was due

The car starts great cold, but if I turn it off and then back on within two hours or less, it cranks about half the time, and when the motor actually catches, the RPMs die rapidly and I have to give it gas to keep it going (old school). Once I give it gas for a second or two it will hold and the RPMs stay revving.

Odd that it only happens when its warm (every morning starts like clockwork, and every evening after work as well). Could it be battery related, or MAF, or even the belts?

 

Alternator possibly? Maybe plugs?

 

i could see any one of those. Your MAF would be throwing codes though. . .run some cleaners through the injectors and replace the air filter. Another possibility is ECU. if it's not properly changing over to the hot-weather mapping, then you may not be getting all the air it needs

 

i have the same problem and i think its the MAF.

 

Alos the fuel relay can be bad, clogged air filter, the battery ground connection may be corroded, Ignition module or main EFI relay may be overheating, fuel injection problem, bad ECM or Coolant Temp Sensor.

 

If it is the ground wire, what grease should be use on it and like the alternator ground, etc? I am looking for the BEST stuff that nobody got bones w/ to protect electrical connections and don't know what to buy...or best places on the car to use it and not make things messed up. Coil wires perhaps?
