Hey, Scotty:
My 2005 Avalon has no codes and runs great with 151k miles on it. It starts with slight turn of the key when cold. After the engine is hot, not every time, but every once in a while, I have to hold the key longer (2 to 3 seconds)to make it start and sometimes it requires two turns of the key to start. No DTCs on Innova 5610 scanner shown. Started using just Chevron gas with Techron and my mpg is gone up 2 -3 mpg after several tanks.
What does this live data indicate? All were performed with a/c operating
ECT 203 (F)
STFT B1 0.8 TO 1.6 %
LTFT B1 -1.6 %
STFT B2 0.8 TO 1.6 %
LTFT B2 -3.9%
ENG RPM 613-626 w/ ac operating
SPARK ADV 21.5 TO 22.0 DEGREES
IAT 154 F
MAF 0.43 (LB/MIN)
TPS 14.1 %
Anything to be concerned about?
Thanks for all your help.
Jim
Your MAF sensor reading is too high, it is a good idea to clean it alongside with throttle body. The other thing is that, you may have leaky fuel injectors which results in the situation you experience.
