Engine Performance problem
1999 Toyota Camry 4 cyl Front Wheel Drive Automatic 15320 miles
When first starting, the Camry runs at a fast idle as expected, but when you put it in drive, it hesitates and stumbles. However if you keep on the accelerator, in a few seconds it takes off and runs just fine.
No check engine light comes on, and no codes have been posted. (I bought an actron CP9180 to test this problem.)
Fuel filter replaced at 135, 782
Plugs and wires replaced at 135, 915
Air filter at 152,000
I sprayed some Gumout into the throttle body but no difference on the next day's starting.
Do you think it may be one of the temp sensors not registering it as being cold?
==> I checked the intake air temp sensor and it showed 1900 ohms, and the air temp is now 80 F so that seems ok. (According to a table in the Haynes manual)
The engine coolant sensor was 1600 ohms, which seems a little low, I will check it in the morning and see if it has more resistance then.
have the same problem?
