lajkowicz Posted January 21, 2005 Share Posted January 21, 2005 When my 2004 Corolla starts the engine, revs to about 2000 RPMs. If still cold, the idle drops to about 1800 and stays there until the engine starts to warm. IF the engine is warm the idle drops to a normal 700 RPM. I have been told by the dealer that this is the correct operation for the engine. Emails, which I have received from the Toyota web site, say the it is "not unusual for Corollas to run with high cold RPM". This statement implies is that not all Corollas idle at high RPMs. My problem is that, just at start up, there is no oil pressure and the oil has drained from the engine. It takes a few seconds for the engine oil to circulate. I think that running at 1800 to 2000 RPMs is racing the engine and that the engine is being damaged. In the first few seconds of running, the bearings are running without an adequate supply of oil or oil pressure. Is anyone else having this experience? What do other owners on this forum see as cold idle RPMs? Thanks 1 Quote Link to comment Share on other sites More sharing options...
fidgits Posted January 23, 2005 Share Posted January 23, 2005 I wouldn't worry. All modern cars have automatic chokes, so a high RPM when its cold is to be expected. As for the oil issue, again, this is a known fact which the manufacturers work their tolerances to! Quote Link to comment Share on other sites More sharing options...
lajkowicz Posted January 23, 2005 Author Share Posted January 23, 2005 The only "automatic choke" on this car is the Idle Control Valve which is controlled by the computer. Yes older cars had automatic chokes which were controlled by a thermostat which opened the choke when the engine warmed. I think that 1800 to 2000 RPM is too fast to run an engine expecially for the first few seconds when there is no oil in the engine. It does take time for oil pressure to build to the correct value and for the oil pump to fill the engine. I also think I am wasting gas at this RPM. Can you tell me what your cold idle RPMs are and whether you have a manual or automatic transmission? Quote Link to comment Share on other sites More sharing options...
josh84p Posted February 14, 2005 Share Posted February 14, 2005 My '04 corolla LE also idles at about 2000 during cold days to. This is normal for almost any car. However, I have not noticed any problem with low oil pressure. I believe that is something you might want to get looked at. It shouldn't cost you anything under the warrenty and it is better to be safe than sorry. Josh ;) Quote Link to comment Share on other sites More sharing options...
Dviperman Posted March 2, 2008 Share Posted March 2, 2008 I had a 2003 Corolla LE(Totaled...not my fault...lol) which was a manual transmission, and now my replacement vehicle is a 2004 Corolla S model. Both cars idled the exact same way you are describing when started cold...so I would say it's a normal Corolla thing on that lol As for the oil thing, I have been told thats normal as well.

XR2003 Posted March 12, 2008 Share Posted March 12, 2008 Most likely you have a 1zz-fe engine. They are known for high idle @ startup & is normal. I admit I was concerned as well @ 1st. 1zz motors are known to have a "weird" idle, sometimes even after warmed up to operating temp. - sitting @ a light - it sounds like it will die, thankfully not often - only after "spirited" driving.

Thanks that is normal for all newer corollas. there is enough oil left on bearings to prevent any damage. just make sure to change your oil every 3000 miles Quote Link to comment Share on other sites More sharing options...
XR2003 Posted March 18, 2008 Share Posted March 18, 2008 Semi syn or full synthetic also help with Cold start ups. Quote Link to comment Share on other sites More sharing options...

Naz Posted April 3, 2008 Share Posted April 3, 2008 yeah that high idle sounds perfectly fine. in my case my camry does the same thing, on cold cold starts it'll idle at around 1700RPM then drop down to 750 after its warmed up. i wouldn't worry about it at all, it sounds perfectly normal. only thing you could do if you wanted, just use synthetic motor oil, i'v seen that the car warms up much quicker with synthetic motor oil, along with better fuel economy/performance/smoothness.
