I am from the Philippines. I have got this Chevy Optra 2004, and I now have problems with my idle; it is fluctuating. We have already changed the tension wire and changed spark plugs, but still it is fluctuating. Anybody out there who could help with what the cause of this is?

I so get what you are saying. I have the same problem. I just hope it gets better quick.

Have a standard Optra 2006, and am having trouble with the computer. The car sometimes does not start, then tow it to the garage, and my guy fixes the timer on the computer. Has only 42,000 kms on it. Anyone else had these problems? I am afraid to drive it in case I get stuck somewhere.

Concerning the annoying ticking noise, my car has the same issue. Found out is has to do with the lock. Just push down the door lock, and the little rattle is gone.

Hi all. I have an Optra 2010, and I have around 37K mileage on it already.
Recently I have this annoying ignition switch sound when turning on the engine (this happens almost the same time or before the engine starts), and randomly I am hearing a knocking sound in the rear part of the car while driving (the car is moving), and after turning off the engine. Already replaced 2 speakers (passenger right side front and rear) due to vibration sound, and now I guess the left driver's side rear speaker also needs to be replaced.
Hope someone here can share ideas regarding the ignition switch sound and the knocking sound after turning off the engine, because I'm really worried this might cost me much later on, especially as the vehicle's warranty will be finished in 3 months...

I plan to buy a second hand Chevrolet Optra 1.8 (year 2005) for RM20K. Any comments or advice on how to check the car?

This is due to the exhaust; when your car is on, the exhaust is hot so it will expand. You will hear a knocking noise or not, and when you turn off your car, the exhaust will come back to normal size, so you will hear knocking sounds.

Sir/madam, I bought a second hand Chevy Optra 2004, and I also experienced the idling and acceleration of the car. How can I fix it, and how much was the price of it when you bought it brand new? I will appreciate your reply. Text me at 09055513346. Thanks a lot.

Wow, that almost exactly describes what happened to my car, they said replace the timing belt, and it did end with a blown radiator and an overheating engine...
Is the timing belt sabotaging it? Also now my MAF sensor is giving out, but I find my car is performing better??? How weird...
