Most reported 2003 Toyota Camry problems
One or more motor mounts may wear out on cars with high mileage. This will put extra stress on the other mounts, and the faulty mount(s) should be replaced.
The valve cover gaskets have a tendency to leak oil, especially the one near the firewall.
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
The intake manifold makes rattling sounds when you depress the gas pedal.
There is a manufacturing defect in the baffle that is loose inside of the intake manifold.
The fix is to replace the intake manifold.
Engine will not idle after a battery change especially when air conditioner is on. Read this is common problem. The computer that controls the engine idle loses it's memory and no longer remembers how to idle. Fix by driving the car between 5 and 10 miles. This puts the lost data back into the computer ECU and now it idles just like it did prior to the battery problem.
