Default 2000 Camry LE Cylinder Misfire

Hello All,

I'm brand new to Camry's just bought my first one about a month ago, 2000 Camry LE with 110,000. About 2 weeks ago it threw the check engine light on, took it into the Autozone to read the error code and it said cylinder 1 misfire, cylinder 3 misfire, random cylinder misfires. Cleared the code, added some Lucas fuel system cleaner on the next fill up. Drove for about 75 miles and it came on again, same codes.

I was figuring on changing out the spark plugs and checking out the wires to see if they needed replacing. The car runs great with no hesitations, smooth idle. Any help or advice would be great, thanks a lot!!

Might be the coil, swap coils. If the problem the codes will also swap coils.

What do you mean by coils?

Ignition coils. Could be a bad coil.

Each coil powers 2 plugs. You post states 2 cylinders are effected. 1 and 3 cylinder plugs are powered by the same coil.

If the ign system has 2 ign coils, swap coils and determine if any trouble codes now state cylinders 2 and 4 have the problem. If so the coil is bad.

Thanks Joey,

I diddnt even realize that it used ignition coils, I've always had a car with a distributor before.

I have another question for you. I have not done any work to the car yet and the check engine light went off, is this common?

For coils, follow the plug wires. If correct these should lead to 2 coils. Each coil connected to 2 plug wires. The engine does not have a distributor but uses pickup sensors on the cam and crank timing belt pulleys.

The light could go off if the problem corrected itself. The computer runs self tests. If the problem corrects itself or is intermediate resulting in no failed self tests the computer will turn the light off.

If you checked the codes you might now find codes that are pending. Meaning a self test(s) has failed but not enough times to have the computer trigger the light.

You're the Man Joey!!!

My car defiantly has coils instead of the distributor, I'll be sure to check those out. You have been a huge help buddy!

The most common causes of a misfire (assuming your car is a petrol one) are the spark plugs or leads. Or it could possibly be a faulty coil (the thing that makes the spark plugs spark), or if it is a very old car, the distributor.
