308 performance help

Hello friends. I bought a 2008 model 308. When I bought the car it was as if it was a turbo and it was quiet and quiet. But 1 week ago, the electric valve and one coil changed. The vehicle is not in its old waste. I got it to the service, everything says normal and the malfunction lamp on the screen does not light up. But they say that it will be so.But I am not satisfied with the performance of the vehicle since I know the previous one week ago. In your opinion, let those who know where the malfunction or error help. Meanwhile the vehicle is a 1.6 120 hp gasoline vehicle hakan574 2016-02-10 13:30:59

is the vehicle automatic?

it's not automatic. manual gear

I understood my teacher, I know that the electrovan is in the diesel, the benzil has automatic, the electrovan is in the room (automatic transmission).

1 even changed because one of them had 2. but the sound in the car screams as if the exhaust breaks out when it presses the gas and it is a little slow at eating gas. I thought it might be an oxygen sensor or an air flow meter, but the service says it is not broken because the malfunction lamp is not on. I couldn't get out of business. I got a little depressed.

more precisely, let's not say that the exhaust is like an explosion, as if they wear sports filters, make a sound like that.

I suspect that it is an electro valve, still, if it is possible, do you have the opportunity to add a photo of the changed part, and I think you had lpg in your vehicle, I guess I don't remember wrong sonerkyl 2016-02-10 15:04:45

yes teacher lpg was fitted when i bought prins brand

There were already interruptions due to the electro valve, it has improved. my current problem is low performance and loud noise. He also says that my master in the industry is not normal, but the service is quite normal.

I understand, my teacher, is it noticeable in the case of poor performance, lpg grandfather?

yes, my teacher, that is, those who say that the 120 hp 1.6 vti engine is not the performance, and as I said, there is a difference because I know the performance of 1 week ago. I tried to throw a picture but I can not find or find how it is done

What is the condition of the press lining, even if the vehicle near the end of the press lining is overturned, it may not achieve the same speed in the previous revolution, otherwise check the air filter housing, is the original filter installed?

Even if the vehicle does not fail, a master who knows the normal values of the sensors can look at the program and tell if the sensors are working properly.

In LPg, it is normal to decrease some performance compared to gasoline, but this will be around 10% max. In the new generation vehicles, the quality system can be kept below this with the right workmanship and good fuel.

Sir, the pressure pad is in good condition, the filters are good, I can say that even new engine oil new spark plugs new gasoline filter, ie oil filter new engine condition 80%. So this car does not eat gas and shouts

it seems to me like a spark plug problem.

the situation you described is similar to the press pad problem

Maybe by resurrection, but I'm having the same problem and all the pejo services are looking at me naively. Did you find a solution and what was the problem?
