    I have a 2001 Sentra and it does the same thing. I replaced the spark plugs and it improved the issue but the check engine light still flashes.

This could be an issue with a Mass Airflow Sensor or the idle valve. The mass air flow sensor tells the on board computer the amount of air coming into the engine and the idle valve controls air intake while the car is idle and the throttle isn't open. If both of these parts are broken the on board computer may not realize enough air is entering the engine for a proper air/fuel mixture. If the on board computer isn't sensing correctly then it will cut power to the engine to prevent damage.

Idles at 900 rpm but when cold revs up to 2200rpm not all of the time some times stals


Your automatic choke is in need of adjustment.

Should be about 2200 when cold and 900 when warmed up. It is not stepping down properly. EZ fix.

High rev at cold (winter cold!) idle


Your toyota technician should know what a "cold starting solenoid" is. It is the little thing that works your throttle until the motor warms up and something else takes over. I'd suggest going to another technician.

Good day: I don't accept that cold starting an engine at 2000 RPM is OK. Those immediate revs on a cold engine are wearing out parts that need oil lube and warm-engine clearances. Is there a simple way of...


I have heard that Fords theory behind that is to supply maximum oil pressure to moving parts sooner. All the Ford products do this and the motors last well into the hundreds of thousand of miles. I wouldn't be to worried about it since there is no issue with it to my knowledge and there is no way to limit the cold start RPM's.

Cold start warm ups are a thing of the past. Better lubricants, engines, fuel injection and other computer controls have made start ups easier on the engine. 30 seconds is barely enough time to warm up anything and after a few seconds oil has already reached all of its intended lubricating points. That first few seconds is the hardest on the engine. Regardless of how any RPM's it is turning.

Need some one help........... I have terrano 1999 manual transmision, problem is rpm unbalance when engine strat rpm between 700 - 900 rpm ac off


The ideal idle rev rate for your vehicle should be approx 800 rpm. If the engine is surging in revs and then dropping off shortly after starting from cold, then it may be that your engine is trying to compensate for the fact that your thermostat has not yet opened. It would help to know if the engine revs settle down after the thermostat opens. Diesels do not have spark plugs, they have glow plugs that preheat the air within the piston chamber so that first starts will occur without a huge drain on the battery, this means that the engine relys on the compression of the diesel and air mixture going into the piston chamber to reach maximum compression and then explode thus causing the power stroke within your engine. But when an engine is cold the engine has trouble sometimes reaching that explosive temperature within the chamber and sometimes not all of the power is released with each stroke of the engine. When the temperature rises and the the thermostat opens the engine can reach the explosive temperature more efficiently and the revs settle down to a more even rate.

Check to see if your air is getting through the turbo alright, sometimes a simple thing like a blocked airfilter can cause symtoms such as what you describe, failing that I would get your Diesel pump checked out, that may have a slight blockage. As an afterthought, have you checked your diesel filter(s) and fuel lines, they may need cleaning out as well. That may cause the rough running until the diesel warms up and flows better through the fuel lines.

Hope that helps.

Low rpm's in idle when heating/cooling system is on & surges.


Check your EGR or your Idle control Valve. This can cause a problem with your irratic idling

Not reving high on cold start


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
