    What about after you drive the car for a while, then stop at a light of something? Is it still revving, or does it settle down?

What can cause the engine on my 1999 Oldsmobile 88 LS 3.8L (3800 series 2) to make a loud air sucking sound in my intake manifold


With the engine running open the hood and look/listen for a vacuum leak. One of the larger vacuum hoses has likely come off.

1999 daewoo nubira (RPM)


Hi,

Based on your description, could be anything:
  • throttle control (including A/C compensator);
  • auto choke;
  • engine management;
  • auto cruise (if your model has one)
A couple of clarifying questions:
  1. What is your standard set idling RPM, 1000? with or without A/C?
  2. Automatic or conventional/manual trnasmission?
  3. When was the last major tune-up? What parts were replaced?
  4. Does it sound like misfiring also?
  5. Any other indicators, hard starting, long warmup, stalling, excessive gas consumption, smarting to the eyes exhaust fumes?
  6. Does your battery light lits up?
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.

Lotus Esprit S4 NOT idling correctly


the se esprits the s4 and s4s series are programmed to speed up engine rpm and close off the exhaust back pressure valve to speed up the heating of the catalytic converter to operating temperature and is quite normal regardless of engine temp. if you quickly blip the throttle pedal a few times it should settle as the cat temp rises if that is the case then it is all working as normal.
