Recheck over your steps when you changed the air filter. Make sure nothing came loose like any electrical connections or rubber lines going to to intake hose. Sounds like you may have a vaccum leak or possibly have a sensor unplugged. Check Engine light come on? ....Or changing the oil and air filters maybe just a coincidence of the problem actually happening. Maybe someone else will chime in and offer some more help.

I have had the same problem when I used to own that same year and model. I replaced the idle speed actuator, worked for a few months and the problem came back later. Until I blew a spark plug cause of engine misfire (replaced all six plugs) and ran acceptable for a months until I had white smoke come out of my tail pipe and when I was lucky to clear the engine filled with coolant (hydro lock) a low coolant light went off. Many people believe that the cylinder head gasket or cracked internal engine part could be the problem, but I got rid of the car then. This may or may not be the case but that is my experience

not sure i have the same problem, mine just feels like its running high rpm. shifts ok i guess, but turning 2K at 50mph. idling 1-1.5, turning under 2 at 30-35 then again at 40-45 mph. otherwise turning 2K+. maybe its just a little car and that's what little cars do, but seems like something might be off. is "datdude" on to something in my case?

It could be your intake manifold gaskets are shot. This would alow for air to pass through your intake manifold where the intake meets the the rest of your engine causing a high idle how high of and idle depends how bad your gaskets are. Had the same issue I replace them (it was a pain in the ass) but it fixed the issue

I have the opposite problem. When I start my car it will go from 1000 rpms down to almost zero then back up to 1000 rpms back down to almost zero the lights will also flicker. Any suggestions? The dealership says they cannot find anything wrong.

had a customer come in with this exact sympton. very hi idle in park and once put in gear , the idle comes down. however . he told me that he went to another repair shop and they tried putting a tps sensor and an idle air valve and last but not least a pcm.... twice... lol we pulled it in to the shop and it was screeming away at around 3k rpm. plugged the scanner in and everything looked normal. with no codes . we back probed all circuts at throttle body , tested all the sensors for ground and power. all were fine . checked for intake gasket leaks with a smoke machine and out popped its ugly head. a stuck egr valve. removed egr cleaned out sut from hole in motor, and replaced with new egr and puff!!! a fixed car your welcome. slight stuck open egr valve... very slight

My 2001 Chevy Malibu revs to 2-3 when put into park. Hope this isn't a transmission problem. I just got the car in April 2016. I had the guy I bought it from look at it and it seemed to be ok for awhile and now it came back and is doing the same thing every now and then. Please help and send some advise to bhasenbank50@gmail.com. Thanks!
