Have you checked for codes in the ECM ?

Recommend you do this first and if any codes, they may indicate a possible problem that is causing your poor acceleration.

### If 360 km per hour is equal to 40 miles per hour, please show me how to calculate using formular

360 km/hr is NOT 40 miles/hr.
1 mile is about 1.6 km
To go from km to miles, multiply by 0.62
To go from miles to km, multiply by 1.6

Kilometers per hour to Miles per hour

### My opel signum does not accelerete it can not drive more than 20 kilometers speed

if you have a engine managment light on then you are in limp mode you will need to have the ecu read to find the codes, i would say its a cam sensor. as that is the most common to fail. they get a lot of heat on them from the engine as does the crank as it sit in the bottom end of the engine. but you will need a engine code reader to find the fault to be sure what sensor has failed.

install a spedometer with kilometer markings or manualy paint markings on at proper locations. 88 kph = 55 mph, etc.

if you were thinking you could push a button, not gonna happen.

### The engine started running rough,and a short time later the Yellow Engine Light came on and shortly after that the yellow light started flashing every time the engine was revving at a high speeds between...

Stop by any good parts store (Autozone, Advance, etc..) and have them do an OBII scan (fault scan) They will pull codes and that will identify what's troubling your truck. Most will do this FREE

### I bought a used 2003 A4 Convertible Audi 3.0 Feels it burns more gas than expected. Is there anything I can check or do to reduce that. Thanks Sean

to see what you get for mileage, take it to a gas station and fill it till the pump stops and reset your trip meter. Drive it around like you normally would to work or whatever till the tank is almost empty and go fill it up again till the pump stops. Its best to go to the same pump you used before. Once it is full look to see how many gallons or liters you put in(This is how many you used since the last time you filled up). Take the number of miles/kilometers from your trip meter(the number of miles/kilometers you drove since you last filled up) and divide it by the gallons/liters you used and you will get your miles/kilometers per gallon/liter. Compare this with the rating your vehicle is suppose to get. But remember it can very depending on how you drive.
Miles/kilometers divided by gallons/liters
