What is the reason for engine retreat while driving?

Asked by Apr 11, 2015 at 07:48 AM about the 1999 Hyundai Elantra

Question type: Maintenance & Repair

I drive Hyundai avante automatic gear with lean burn system on the engine.
while driving on steady speed, things are ok. But if I slow down a bit and try to accelerate again, it takes long time and RPM starts jumping up and down. I have noticed also that when I start AC while engine is idle, RPM keeps jumping between 700 - 300. Same happens when I put gear on drive if I keep pressing the brake

Any lights lit up on the dash? Sounds like a vacuum leak or a dirty throttle body or an issue with the idle control valve. When was the last time you check the spark plugs and ignition components? Change your filters?
