Question about 2002 Toyota Camry
4 cylinder with 160,000 miles. the only maintenance I have done is oil and filter changes
Your car probably requires a comprehensive engine tune up.
During engine tune up mostly three areas are addressed:
1. Restoring the cylinder compression.
This system requires the adjustment of valve tappet clearance at operating temperature.
2. Servicing the air and fuel system.
Servicing and inspecting the throttle body, ISC (Idle speed control valve), element air cleaner and MAF ( mass air flow sensor)
Fuel pump pressure approx. 38psi - 44psi.
3. Servicing the ignition system.
Inspecting and/or replacing/adjusting the spark plugs gaps(0.9mm-1.1mm), igniters (visual inspection)

I agree with Shadab, look at the Idle Air Control valve. They are expensive, so see first if cleaning it does any good.

When you take your battery out and put a new one in all your computer controls have to be reset. You need to drive the car at 55 MPH for 2 min or so, stop, go through normal drive cycle, stop and go and then if it don't straighten out you need to clean the throttle body and the idle air control valve. Hope this helps. PHil

SOURCE: maintenance required
That is a friendly "get the oil changed light" and a reminder that a 25K service is due. To get rid of the light, push down the "A" trip reset button, turn the car off (while holding the button down), and turn the ignition on but don't start the car - while still holding down the A reset button. You'll see a count up meter on the display that will tell you when the system is reset. Enjoy.

Check the manufacture's Cold Cranking Amps (CCA) rating. Some manufacturers recommend a minimum CCA. If your CCA is below the manufacturer's specs, it can cause your car to run erratically. This also can cause problems with your computer and give you faulty DTC's. (Diagnostic Trouble Codes - Service Engine Soon Light) This especially causes problems with General Motors cars. I'm always hearing of people with these problems. Let me know how it works.
