Gearing failure SolvedSolved

Chevrolet Epica 2007  157000 miles
Hello, my Epica has been inactive for almost two years because it has a failure that no one has been able to solve yet. Its problem is that, when setting the first gears, revolutions raise almost to the top and then suddenly drop. When this happens, the car hits really hard; so much that, when it does, the yellow engine light turns on, not allowing me to accelerate, losing power and driving almost neutral. I need to turn it off and start the engine again so that it continues working properly. I really need some help.

Have you scanned your car?

Yes, randall22. My vehicle was scanned but no error code was indicated.

What you need to do is to service the throttle body, and it will definitely get better: 1- remove the battery. 2- take out the MAF sensor, blow it and apply some spray for cleaning the carburator. Disconnect the thick hose that goes from the throttle body to the engine and clean it with the same spray, including the two little holes. 3- clean deeply the throttle body's turning device so that it has a better mobility when opening and closing. If you are able to remove the whole throttle body, that would be the ideal thing. You need to replace the air filter as well and clean the ducts that lead to the MAF sensor. You then wait for the spray to dry and try starting the engine. Please tell me if it worked. Hope it does!

levone, after taking the car to many different mechanics, the last finally found the problem and, effectively, it was the throttle body. It was dirty, he cleaned it and the strong hits and engine light disappeared. The only bad thing now is that it slowly hits when setting the reverse, just as when I decelerate it at 12 mph. Even though they are lightly felt, I am worried it can get damaged again. I was told that, as I drive it, the soft bumps will disappear. The only thing the mechanic told me I can do now is to buy a new throttle body. Is it expensive? Thank you very much for your comment, you were right.

Change your oil to a synthetic oil for automatic transmission and you will see how it gets better.

I have 2008 Chevrolet Epica and appear to have some kind of electrical fault. A few months ago I could hear the passenger door making a sound as if it was trying to lock or unlock when I used the central locking fob. The doors did lock so no problem i thought. Now the doors lock while driving especially when I indicate, the central locking button in the car no longer works and the doors seem to have a mind of their own - locking or unlocking. When I use the fob to lock the car, it will lock and then unlock itself, i do this a few times and it will remain locked. Any help ?

Acceleration failure SolvedSolved

Chevrolet Epica 2007  120000 miles
When driving at a certain speed with my Epica 2007 and it is accelerated, the vehicle suddenly loses control of the acceleration, maintains 1000 rpm, it blocks itself and the yellow engine alarm appears on the dashboard. I partially solve it by placing the speed lever en neutral, turning the engine off and then starting it again. When doing this, the acceleration is restablished but the engine light remains turned on. I would like to know which might be the failure.

Hello. At the entrance of the throttle body, there is a thick hose that is on top of the engine. Remove it once a month and clean that entrance with some cotton and alcohol. I had the same problem and it was because too much coal was acumulated there. Clean it the deepest you can.

Many failures

Chevrolet Epica 2009  5000 miles
The engine light indicating it needed to be serviced suddenly turned on. One month later, one of the hoses was broken, and the following, the antifreeze container. The next moth, it started indicating that the air compressors were failing and, today, the radiator broke down. I am really wondering what is wrong with this car, I am absolutely deceived.

This car heats the oil more than it should so, even though you might see the oil in the stick to be clean or really dark, open the oil cover anyway and check if it has an oil paste at the bottom. Be careful with this and clean the oil deposit filter because, if it is blocked, the engine will get damaged.

Good morning, I have an Epica which presented many failures similar to yours. Apparently, all the inconvenients have to do with a manufacturing defect which is in the catalytic converters. When an emptying labor was done to mine, both the oil consumption and overheating problems were solved.

When buying my car, I have also emptied the catalytic converters and installed a flow master to it. Even though the oil consumption is still high, the vehicle flies, it has a lot more power than before.
