2005 Santa Fe with noise

Describe the noise very specifically ; is it a whir, a knock, a hiss, a clicking, a vibration, high pitched/low pitched,etc ??

Have you tried this : Have a driver sit in the suv with trans. in Drive, parking brake on, foot on the brake pedal, and chocks in front of the wheels ...and as the driver gives it bit of gas... you stand to the side of the car with the hood open and listen .

Yeah, what kind of noise. If its like marbles in a can, it is pre-ignition. Get some better gas or retard the timing at touch.

Set up the video camera for this one, this could be one of those "me and my brother-in-law tried this once" moments. LOL :) But may be a good way to try and isolate area of noise.

REPLY: The O.P. did this , and he emailed me. He said the noise occured. Theres nothing wrong with doing it this way, so long as safety is considered above all else.

No offense intended, Dave. You did specify good safety precautions.

It just brings me back to some of my own ill conceived and hair brained schemes or watching my Dad "troubleshoot" equipment over the years. He woke up once lying beside his pickup in the snow! The tow rope broke, snapped back, caught him on the top of his head as he poked it outside and around the open drivers door. Big welt, big headache, and big laughs. Course how many times have we had our nuckles whacked by the fan, or picked up a good shock from the plug wires.

didn't mean to hijack coco's thread.

Theres nothing like getting your Timing Light cord in the fan as your checking Timing on an engine ; all of a sudden everything leaves your hands in a hurry and youre left holding nothing !
