Where do I post this? 2000 Toyota Echo is hesitating....

[gruvee87vertgt]

swapped the plugs last night.....still hesitating....

it does it sparadically......regardless of warm or cold.

it does it when it's in park and stopped when in drive...not when accelerating...


talk to me people!

Try replacing the wires leading to the plugs.

It has four individual coils!

Can you elaborate further on that? How is it still not idling right? Idle rough or ?

What does 'it does it when it's in park and stopped when in drive...not when accelerating...' mean?

If it is the coil, it should have set an engine misfire code, do you have a CEL?

Hesitation could have been cause by a lean fuel system, dirty MAF or restricted injectors maybe?

N.E.O.

I am having the same problem with my 2000 Toyota Echo. My check engine light is on. Last year the mechanic did his check and had me by an O2 Sensor. The check engine light still came on.

This weekend i went to Auto Zone and bought some MAF cleaner. I was told to spray the cleaner on the thin wires inside the hole. So I sprayed it several times. The instructions told me the check engine light should go off at the next system check....

My question are the thin wires in the hole the sensor or is that part that you pull off the sensor? Should I spray the part that I pull off?

Does that make sense?

Thanks

Instead of just cleaning the MAF sensor, you might want to find out what your current code(s) is. There are other circuits that can cause the CEL to come on, and MAF circuit is but one of them.

For your questions about the MAF, you have to remove the MAF sensor by taking out the two small screws, take care not to lose them. The portion of the sensor that goes into the intake duct is the part that you need to clean. Take care not to get the cleaner on the O-Ring, not good for it. You can disconnect the battery cables, negative first, and touch them together to clear the code; however, you better be sure that it is the same code first. When you connect the battery cables again, the ECM might take a little bit of time to 're-adjust' itself so the engine may not necessary run very good.

Keep us posted.

Has this problem been happening for more than your current tank of gas? You might have nothing more than a bad tank of gas from your last fillup.a couple of bottles of water evaporator/displacement might be the cure.They call it gasline antifreeze up here.

I have had this problem with my check engine light being on for well over 14 months. Last year took in to shop and was told to get o2 sensor...spent close to $200.00 dollars and it didn't work.
Was fixed last year for about 20 miles and then came back on.

After I cleaned the MAF last week, the check engine light went off for 2 days. Came back on. Bummer, I didn't take to get inspected and my inspection is up after this month. I have tried to clean sensor 2 more times since and nothing different.

What is o ring?

Any other ideas? I am getting desparate.

Thanks

When you pull the MAF sensor, you didn't see the o-ring used to seal the sensor to the intake duct?

Unless you pull the code, there isn't much we can do, as I had mentioned, we need to know what area it is that the ECM is seeing a problem.

N.E.O.

[drshawn]

how do I pull the code? is that running a diagnostic?

[new echo owner]

No that is just retrieving the code from the ECM's memory. The diagnostic part comes after you know what area of the Engine Control system you are having problem with. Some of the other members mentioned that some of the AutoZone stores will pull codes for you for free, might want to give them a try if you have any AutoZone in your neighborhood.

I've got an autozone near my house. What do I exactly ask them?

Tell them you have a check engine light, and ask them if they can retrieve the code for you.
