Funny noise when accelerating

Hello: I just bought the car listed above. I have never had a front wheel drive vehicle before. This one is making some gurgling/clattering noises when I start it up and put it in gear and accelerate. I have been told this is "normal noise for front wheel drive". Is that correct? If not, what can that noise be? I do not see anything loose or coming off on the engine.

Also, how often should it have a tune up?

Thanks

I do not know about the gurgling noise but the clattering noise is normal. A lot of the vehicles now are going to direct fuel injection. What that means instead of the fuel injector spraying gas at the intake manifold it now sprays it directly into the piston bore. That will cause the clattering noise.

On a side not I strongly recommend you use premium fuel on your vehicle. Cheap fuel will carbon up the intake valves and the pistons. Symptoms of carbon build up will be misfires and oil consumption's. If you do lots of stop and go driving or baby your car you should take it on long highway drives to burn off the carbon and use a fuel additive. The dealer additives work really well vs. The over the counter parts store additives.

Hope information helps but you should get a second opinion from another shop also to verify it is the injectors making that noise which is normal.

Hello:

I have been trying to make an appointment for a mechanic, but I am not getting responses from any of the places I have contacted so far.

I will start using premium gas now too. It is rare I ever get on the highway, so I will make a note to take it out once a week.

I have also noticed, that the noise is not as loud when I turn the traction control off. Could this have something to do with it, or is it just coincidence?

Okay, thanks for the information!

Hello,

As far as the tune up duration it is a good idea to tune up your engine about every 45,000 miles.

Here is a guide that will show you what you are in for when doing the job.
