Acura troubleshooting The care has a 1.7 litre V-Tec engine, when I hit 3000 rpm, there is a whirring/ticking sound. This sound also occurs when I accelerate while the car is still warming up. What could the issues be?

SOURCE: ticking noise

A small exhaust leak can sound like a ticking noise during acceleration and can get better or worse as the system heats up. I had a similar problem when the engine was cold that was solved with a new exhaust manifold gasket.

Throttle position sensor or a vacume leak.

SOURCE: Vw polo maintains engine revs when foot is off the accelerator.

You need to check the cable the runs from the gas pedal to the engine, it might be rusty and need some drops of penetrating oil at the point it meets with the engine accelerator valve.

Have exactly the same issue on 04 jag x type 2.5. So far have replaced fuel filter, air filter k&n, plugs ngk. Codes cleared, same issue. Seems to appear when air temp is cold and eng is warm.
Am replacing upstream O2 sensors and cleaning MAF next. Will keep you posted if it clears up. Did you ever find the cause?
