    Same problem. This morning the mechanic said I needed an ERG valve. I also need an alternator; probably not related problems.

The first thing to do is have the system computer checked for trouble codes, then with those codes we can find the problem with a little luck, Kragen and others do this test for free.

My 1991 Toyota Corolla drives fine and then suddenly it starts to hesitate.


mine did the same thing and it was oxygen sensor
since engine light came on there should be an error code
on computer.Get a diagnostic checker or take to a garage and have them hook uo to the diag connector. I bought a diagnostic checker few years ago and it has come in very handy
sure hope this helps!!

How to top up fluid in transmission


Drive the car for about 20 minutes. When you stop and check the fluid, leave the car on level ground and the engine on, in park and with the parking brake on. Check the fluid - it should feel pretty warm. Confirm that you have the proper type - the dipstick may say what type to use and the owner's manual definitely will. The fluid should be added to the tube where the dipstick came out of in small amounts. Add a few ounces at a time if any is needed at all to get it to the upper mark. Don't overfill . If it's only a small amount low, leave it alone.
