This sounds very much like a failing fuel pump. Modern fuel injectors are " self
cleaning" by design. Rarely do they need to be "cleaned". You need to have someone
check the fuel pressure and see if it drops at higher temps. It may be generally low.
Being nearly 8 years old and in a hot climate (+110..Yikes), it's a distinct possibility.
I thought we were roasting here in Cleveland in the high 90's. I'm not complaining
cuz my butt's going to be freezing in 6 months. Here, we get a rash of fuel pump
failures when the weather turns hot.
