steering wheel vib while idling?
Hi, I have a 99 maxima (65k mile) that I've kept in fairly good condition. Recently I've noticed that while idling (after the engine has warmed up), the steering wheel vibrates slightly. I checked the engine idle speed and it is between 600-700, and according to Hay's repair manual, this is within spec. When I turn on the AC, the RPM increases slightly during idle and the steering wheel no longer vibrates, however, I do sense vibration under my seats. Once I turn off the AC, the vibration returns to the sheering wheel. When I am driving, it is fine. When I am idle, the shaking stops once I shift to Neutral. It only occurs if I am in D or R. What could be the possible cause? The vibration is not a lot by all means, but it is definitely noticible. I did try a Chevron fuel injector cleaning bottle but I don't think it made any differences. I've recently did a 60k maintenance at the dealer. I do not feel a lack of power from the engine. Thanks. Raymond |

4cyl toyota's are noted for this, a lot of fwd cars experience this to some
extent as the p/s rack is mounted on the engine subframe and some normal vibration can be transmitted up the coulumn. Question is this is a new problem, right? If this is a vibration, not a rough engine, like a miss fire, you might want to have the engine and trans mounts checked for cracking or deteroration. > wrote in message ... > > Hi, I have a 99 maxima (65k mile) that I've kept in fairly good > condition.

Oh, and if the radiator > is on rubber mounts, check those, too . Hi, thanks for the reply... The vibration is relatively new. The degree is not severe, as I've asked the dealer to check for it when I did an alignment and they claim they can't reproduce it. But I suspect they did not spend too much time on it, because it only occurs once the engine warms up. Well, I do not know how to check or replace engine mounts, is it hard? (I am just comfortable opening the hood and check fluid levels, maybe if I really want to do it, replace engine oil and break pads). I did look at the engine from the top and nothing obvious seems lose. So I guess I need to find a mechanic (dealer?) that I can trust to take a look at this. Anyone know of any in the SF Bay Area? Thanks. Raymond |

I am not a car expert, what is the sympton of a rough engine? I do not notice any unusual noise from the engine, only that it doesn't seem to be as smooth at idle. If it's the engine mount that's lose, how come the vibration goes away as soon as I hit the gas padel? Wouldn't it be more? The Haye's Repair manual mention things like vacume leakage, fuel pressure, etc... could those be causing this problem? (maybe those have more severe symptons, but I am not really sure about those...) Thanks. Raymond |
