Chevrolet Optra Engine maintenance

[Kwanheng]

Accelerate faster? will try to do that..

I realized my car is also jerking during idling and lots of vibrations.

Read up some forum on the internet and they recommend resetting of ECU

Has anyone tried to do that before?

at your car age, your crank and cam sensor might be gone liao.

 

i got them on hand, do call me if u need them.

Always pump my tyres to 230kpa (biweekly)

did a carburetor cleaning and changed fuel filter the previous servicing

Also tried using before STP complete fuel system cleaner, gas treatment, octane booster, fuel injector cleaner..

None of them help

stop using all those STP thing, it will destroy your old engine with out helping out.

 

i used a engine flush at 120k engine, 1 week later i got a gasket leak and im leaking engine oil.

( i learn the hard way, if all those can of STP can cure then, theres no need for car workshop to be around liao )

 

if its FC you want, you need to maintain the car well to get good fc.

 

use 5w 30 engine oil.

 

i just checked, im getting 9.7 per litres for a 2006 optra AT with 155k millage.

Yes, now I remember, when I got my car new back in 2005, I had this vibration problem too and it was this sensor which is not install properly and the line touch the hot engine block. It was replaced by the AD then.

 

Make sure the sensor line did not touch the hot engine.

Last time i chg at 70k km. Now coming 140k km i inspect all still in very good condition so i wil chg at 150k km. So although handbook say chg 60k km i now drag to 80k km. Hee.

[Pisces69]

Need Help!

 

My 2005 chevrolet optra5 (A) 1.6L has FC of only about 8.3km/L

stock car, 14" rims and driving as light as possible (rpm never more than 2500)

 

Really no idea what's going on...

 

 

When i bought my optra est auto also 9-10km/lit wh 14" steel rims.

 

Then chg 16"sportrims got 10-12 km/lit.

 

Then did grounding now getting 12-14 km/lit.

 

Very happy wh this so no more mods to do. Hee.
