Hi Every one, I have a very interesting problem on my hand. MY ES300 recently popped up with TRAC and CEL Light. I took it to my Mechanic and 3 Codes came on reader. P1130 twice and P1135. Mechanic changed the MAF Sensor and also Bank 1 Sensor 1 Air Fuel sensor. We reset the light and I took off. Light came back on after a few miles but this time we only have 2
P1130 codes. We looked into details and this is what the reader showed

Fuel System 1 Fault
Fuel system 2 nothing here
STFT Bank 1 -20.3%
LTFT Bank 1 47.6%
STFT Bank 2 1.5%
LTFT Bank 2 -1.5%
RPM 843
Intake Air Temp 113 F

Any Help will be appreciated

Have you visually checked the condition of the hoses? Has any work been done to the engine in the past several months prior to the light comming on? I would also check for leaks. Does your scanner give you updated trim numbers? If so you can easily use a UN-lite propane torch to check for leaks in the intake. With a low flow of propane, when the flow is pulled into a leak, the short term trim should change. You will probably also hear a change in idle.

Thanks for the details George. NO work done recently. I tried checking out all the hoses but no leaks. I left it at my mechanic and he will check for leaks.
