SOURCE: rough at idle and under revs

Sounds like a vacuum leak. A handheld propane torch is probably the easiest way to find it.(FLAME OFF)

The Quantum can start and idle but does not have power to drive off.


You need to be looking at what controls the engine. Throttle position sensor, air control sensor, etc. Get someone to plug in a diagnostic unit before you spend any more on guesswork parts.

My corsa 1600starts doesnt want to idle and dont ref up at all pls help me


possible low fuel pressure caused by bad fuel pump, bad fuel pressure regulator, or dirty fuel filter. Could also be stuck EGR valve, which can often be removed and cleaned.

My Toyota Quantum 2.7GL idles but does not rev up. i ve changed the fuel pump and filter but still it starts, idles but does not rev up when you press the accelerator?


We do not have this model in US, but I assume it is a new model 2016-17. You throttle (and the "rev" ) is controlled by the computer. The fact that your car is idles - should mean that your computer is fine! There are two types of idle control: 1st- when you have a bypass of the throttle, which lets the throttle flop stay close while idling and let's the air into the motor through a bypass and electronically controlled idle switch. Inspect your throttle - the electronic/metal unit located on the large pipe through which the air gets into the motor: if you have a "bypass" for the air then you need to inspect your throttle body as it could be your problem.
2. most likely you do not have a bypass and your idle is controlled by your throttle body, then it is sure working fine and your only issue is that your engine computer does not know that you press the accelerator. Your gas pedal has an electrical unit on it which connects to the engine computer- inspect the connector/wires if all looks fine most likely your accelerator sensor does not work- you need to change the gas pedal unit ( I think it called accelerator sensor).
Good luck.

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
