#13210 of 13620 Is this the dreaded ISS problem? by jons01

Aug 29, 2006 (11:30 am)

I have a 2001 Impala LS with 41,000 miles and it has been a great car so far. Lately I have been feeling and hearing a "tapping' or clicking sound in the steering. It can happen almost anytime the car is moving, but seems more associated with braking or releasing the brakes. Can my local repair shop diagnose the problem correctly or do I have to take it to a Chevy dealer? Also, what is a fair charge to service the ISS?
 
Thanks

Good to hear from you again! I'm pushing 98k on my 2000 Impala, and still enjoying the ride!
 
I had my ISS serviced pretty early on; I don't know how complicated the process was though. My understanding is they simply drill a hole in the steering shaft and tap in a grease fitting, but I've never taken the time to dig around and see where that fitting is (could be under the dash or the hood I suppose).
 
As for the heat/ac lights, I've had one of mine go out (passenger side), as well as one or two on the radio. I asked the same questions about the temp controls, and as I recall someone here posted that the controller is one complete unit, so not something you can easily take out and replace the bulb. When my driver's side window switch went out 2-3 years ago I kept the old switch just in case I was able to use the bulb from that to fix the one in the temp slider, but I've never tried to tackle it.

Could be the ISS, especially if you notice it while braking and turning (especially to the right, as I recall). Mine started out more as a "feeling" in the brake pedal and steering wheel, and eventually it got strong enough that passengers could hear/feel it as well. Mine was repaired under warranty several years ago, so I have no idea as to the cost. But if that's your problem I'd probably take it to a dealer, since they'll be familiar with the problem and should be able to rectify it pretty quickly.

#13213 of 13620 Engine performance by lightknight3

My 2003 seems to get about 17 mpg in the city and I took it to the dealership because when I rev up the engine in park it cuts out at around 4k rpm so I thought I had a plugged catalytic converter. They told me the computer had no codes what so ever and that the car had something called a rev limiter. So I am just trying to make sure I am not getting a line fed to me. I would also think that it should have significant power but my 04 base malibu can stay right with it.I have changed plugs, wires, cap, and rotor and still get the 17mpg(note that it has the police package)as well as still cutting out when I rev it up. Thanks again folks!

If you've got the police package that city MPG figure is probably accurate, since the police package is A) geared lower (quicker acceleration/worse MPG) and B) heavier (my understanding is that several parts which are aluminum or similar light metal on the civilian Impala are made of heavier steel/iron on the police package, like the wheel spindles and maybe the engine cradle).
 
As the for rev limited, the only time I've encountered it in my 2000 Impala was in testing the upper limits of speed (on a closed course with a professional driver, of course! ). There is a fuel cutoff on the civilian Impala at 108 MPH; I think the police package was supposed to be limited to something like 120 MPH. I've never tried revving it up to see if it cuts off or not (no tach on my base 3.8l), but if that's the case then I suppose you could simply drive the car off in 1st gear and see if the fuel cuts off at the same RPM (I don't guess that'd do any more damage than what you might do revving it in park).

Thanks for the info. I called the Chevy dealer where I bought my Impala and he said if that's the problem, it will cost $110 for the service. It is just about what you said it should be, so I guess it is reasonable. I am retired and will only put about 2000 mile a year on the car, so I may not have to have it done again.

I've only had mine done once when my 2000 was still under warranty, and I'm approaching 98k miles now, so hopefully doing it once will cure the problem.

I just had my turn signal module replaced today on my 2000 Impala with 70k miles. Symptoms were 1. Working ok, 2. Not working at all, and 3. Turn singal would work, stop working, and then start working while waiting to take a turn. $140 Ttotal, $70 for the part, $70 to install.
 
While there they told me about leaking Intake Manifold. After reading a lot of these messages, seems to be common. I need help getting GM to pay for this or partially paying for it. It's an $830 job. Does anyone have any ideas?
