I cannot wait to get rid of our 2005 Equinox with 120K miles. For the short time being, gotta make do with it.
Somewhat recently, my wife and I noticed on acceleration there was a whine and kinda like an exhaust or diesel sound. I cleaned the throttle bottle, changed the drive belt, tensioner and two of the pulleys. The whine is gone but the exhaust/diesel sound remains, or might actually be getting worse.
The noise is only present when accelerating and goes away as soon as you back off accelerating. The sound sounds like it is coming from the engine compartment and is not heard when in park even when giving it gas. She seems to shift fine as well and the sound is steady as she moves through the gears. I was under the car last night and can't find any obvious exhaust leaks even after plugging up the exhaust pipe. Exhaust looks fine. No smell of exhaust on the interior or from the engine compartment.
Recent maintenance: LIM gasket, head gasket, differential fluids changed, transmission fluid changed at 100K, throttle bottle cleaned, new muffler (last year), new EGR tube (last year) new belt, new tensioner, two new pulleys, last tank of gas a bottle of B12 Chemtool.
Transmission, exhaust, EGR, something else?
