Noise and rough engine

Nov 11, 2004 4 Replies

Hello,



I have a 94 Sl2 and currently have a couple of problems. One is when I start the car I have a screeching sound for a minute or two and it goes away. I currently have gone under the hood to listen to it but cannot id which component is making the noise. The other is with the idle. When I apply the brakes and stop sometimes the car will race and then stall out. Putting it in reverse can also cause it to die. The vehicle has 197000 on it. I change the oil at 3000 miles or three month interval. I just drained as much as I couold out of the tranny and changed that filter. Any ideas or checks I could make would be appreciated. Thanks Jim


Or, if the belts are new and tight, then the noise is probably from a bearing that is wearing out on one of the items driven by the belts (power steering pump, alternator, water pump, idler wheel, tensioner, etc.) This is most likely a glazed belt as the previous poster surmised, but if it is a bearing, sometimes you can locate the source by listening closely. If not, then try spraying the items one by one with a spray lubricant through a spray nozzle tube to direct it to only the bearing areas and then re-start to see when it goes away. (Just do not get any lube on the belt or the related belt drive areas as this will surely cause slippage.)

Good luck!

The belt is bad, or tentensioner's bad. Replace the belt. If it still screeches, especially with power steering, it's the tensioner.

Remove the throttle body, take off the TPS and IAC, and clean the heck out of the TB, and clean the IAC off.

If it's still dieing, note the idle speed and mileage. Low idle, poor mileage, and cold start problems == CTS. A $15 DIY replacement.

car will race

I managed to pull the codes and the first one was an 11. Then it went to the coolant symbol and I read 26. This I believe says the TCC is the problem. If this is true how do I fix that? Thanks

Jim
