2004 Chevrolet Optra LT from Malaysia - Comments

Just changed the rim and tire size. It will do.

Fc about 9.5-10.0/L in 60%city and 40% drive. a bit wind sound though right side when speed >100km.

I have a Optra sedan 1.6A,problem is jerking from N to D, it occurs sometime, to avoid this problem is just soft acceleration after N to D.

A way to safe FC is gentle acceleration and avoid traffic jam area, because this car is heavy, the FC will goes higher in this way.

My car FC about 9.5-10 km/L with 80%urban and 20%highway, I think is OK for this car.

I have an Optra 1.8LT too. I have it for almost 5 years now, and it seems to performed well so far. I have done some minor modification, such as K&N Air Filter, stabilizer, HID lights and changed rims to 17". Stabilizer will help with responsiveness. The petrol consumption is still very good, about 10 - 11km/ litre. The ride is still comfortable for such size rims. My highest speed I got on the speedometer was 192km. Note: I have a full body kit so that add weight. But so far so good.

There are some setback is you have to take good care of the car, and also need delicate handling and care. However, I guess it rewards you when you do that. The only problem I have with the Optra is the ride when I lowered it, and like everyone else said, the battery dies quickly.

Why does the HOLD sign comes out, very very often, I hv to restart the car to take the thinking off, as if the HOLD is up, it will drag the car like for snow handling, and the check engine lights will be up, wat can I do, can anyone recomend me a good mechanic in KL, I need one urgently help, can reply to harveyyeap@yahoo.com. thanks a lot.

I have a Chevrolet Optra 1.8L 2004, have problem with the transmission while applying full stop brakes, transmission jump ones. And sometimes the gear from P to D takes time to engage. Please if any one know how to fix this problem mail me at sayra_karl@yahoo.com, co's I ask many mechanics but they say that to overhaule the transmission but why!the clutch are not burn and while driving it shipt very well.

I have bought chev optra 1.8lt 2004 done 37000 km and we programmed the tcm calibration with the latest software calibration to improve shifting as per description of the program. this issue is about jerking when shifting the gear from "n" to "d". but the problem is, when performing the program it fails when reaches 70% of the downloaded file. I tend to perform the program due to the jerking concern and as describe in gm bulletin.

Please somebody help me to restore my previous calibaration file.
