Why does it sound like there is a trumpet in my engine when I stop at a stop sign or signal light?

1. Answer: The engine noise, it is impossible for us to help you here without listening to the engine ourselves. As for your idling problem, check all the vacuum hoses and intake manifold gaskets as you might have a slight vacuum leak somewhere. In addition, check the idle speed control motor to make sure it is operating properly. If all checks out okay, scan the computer for fault codes. Scan the computer for fault codes. Also, check the oxygen sensor and coolant sensors and also Check your EGR (exhaust gas recirculation) valve it sounds like it is stuck open and needs replacing

SOURCE: making a knocking noise

This is most likely either a piston noise or a connecting rod bearing knock

SOURCE: I hear some noise coming

Wheel Bearings would make the Sound Constantly while in Motion. You have a Gear box Problem. Are you still under Warranty?

That's where I'd go first. check with driveline unloaded (neutral with wheels off the ground.)

SOURCE: Loud rattling noise while accelerating

First thing i would try...... ISOHEET, Red bottle..... allows water to be mixed into the fuel and be burnt out of the tank.
get a good qaulity fuel injection cleaner, if you can locate the brand MALCO, i found it quite succesful..... and go with a full tank of premium fuel such as ammoco or shell......do not use yellow bottle of heet

Testimonial: "Might be water in the tank?"
