I have 1998 Toyota Corolla CE Automatic. Check light is on.

Check the fuse. Check the element with a digital voltmeter set to ohms. The wear out because it is just a coiled heating element. Borrow one from another vehicle to test.

Depending on the miles, the fuel filter might be getting clogged. Other then that, it will probably have to have an analyzer on it. Wish you luck with that, it can be so frustrating.

The "check engine light" or MIL (malfunction indicator lamp) is telling you that the power train computer is holding a diagnostic trouble code (DTC) in memory. These codes set when a problem with one of the many engine sensors is detected or engine parameters exceed expected programmed limits. A code reader tool is needed to read out these codes and explain the definitions. Most major auto parts stores will read out your codes for free.

Even if your car is running fine, do not ignore this light. In many states, your car will not pass an emissions test with the light on. Many faults that will set codes are related to proper emissions control. But many faults that cause emissions problems also cause poor gas mileage. So if you ignore the light you may very well be wasting precious gas dollars.

Hi, I believe their is a TSB for your model. You'll want to check with the dealer because if the ECM needs replacement it should be covered under the emissions warranty. More info @ P0607

It should use R-134 rather than Freon as the ban on Freon began in 1994.

I am trying to understand your problem. Check engine mounts. Have a driver in the car, hood open. Start car, foot on brakes, shift from park to reverse and back again. Shift through all gears, look for unusual engine movements around engine mounts area. Left foot on brakes, press gas in drive and reverse;watch for excessive engine movements. Be careful as you perform these steps. You may also want to check drive axles. Keep me updated.

check the brake disks. surface should be cleaned. also check the brake pads.

altanator needs to be checked may need replacement

Check the idle speed.
