2003 Mazda 6 v6 - problems
I just bought my Mazda 6 in November. I love my car, but there are some problems that have my mechanic husband and friend stumped:
There is a high pitched hissing sound coming from the right (passenger) side. We've heard vacuum line/hose/pump leak could be problem; bearings in alternator; bad throttle body. Depending on the computer you put in to run codes, you'll be told there are cylinders misfiring, or codes going back to the throttle body.
Whenever I pull up to a stop, there is a faint burning smell that comes into the cab. The car isn't overheating and there is no smoke.
Last week, my husband was waiting for me when all the lights on the dash came on. When he started the car, the engine began to surge or rev (rpm's were up and down, up and down). He had to turn the car off and on again several times before the engine stabilized.
We took the vehicle to a mechanic and he replaced a radiator coolant connector hose that is T-shaped. My was a lower case r shape with cracks throughout. I picked the car up yesterday and....the high pitched hissing noise still present, the burning smell in the cab is WORSE (I had to drive with my sunroof tilted open to funnel it out), and the surging started again.
Any ideas, anyone else have any of these problems? We know we need to take it back to mechanic, but we want to have some kind of idea of what we're looking at since we're getting mixed messages on what the problem(s) is with the vehicle.
