Big failure 
Solved
Chevrolet Epica 2007 240000 miles
My Epica has been inactive for two months, when a huge failure suddenly appeared. I started the engine and it did, but almost instantly stalled. I've already changed filters, spark plugs, fuel battery, the battery, the radiator and the car has even been maintained but after all this, it worked properly for one day only; the following, the failure appeared once again. If someone can help me, I would be really glad.

Some days ago I solved the same problem as yours, which left my car inactive for months, just as well. I bought a new MAF sensor and that was it. Hope it helps you.

Hi, I bought an Epica with 78000 miles and, for almost two months, the car worked without any problems.

Some days later, a failure appeared: the vehicle starts working properly but, when reaching a temperature of 80 degrees, it stalls. After some minutes, it starts working again, but only but some meters, and it stalls once more. When contacting the car, the fuel indicator does not raise, until it cools down. It has been scanned and the ECO failure was indicated, referring to the automatic transmis… Read complete

Good night, I have three Epicas and all of them have had your same problem. What you need to solve it is to clean the injectors and change three little wires from a sensor that is located on top of the engine. It is a failure that appears every 50000 miles. Hope it helps you.
