When I start the car rpm goes up by itself without revving. If I put the car in drive rpm goes to normal but temperature rises to H once I hit the brake or put in park.

My 01 Pontiac Montana is trying to overheat at high power


If your vehicle doesn't actually overheat, just getting hot, I think that's the normal behaviour for these cars. My 03 AWD behaves the same way. When driving uphill, especialy when towing, the temperature rises close to the red marking, but I have never experienced it overheating. I think that the temperature has to rise much over the normal driving temperature to activate the two electric fans.

I have a 2006 Scion XA. Few days ago noticed revving sounds while driving the car. Originally thought engine was revving but noticed RPM gauge is normal. The humming/revving sound starts about 20 mins...


under the bonnet on the radiator is an automatic fan, now if the radiator is low or you need to replace the coolant in it or top it up but the car may need a service and let them know the problem.

Engine problem idle speed


Hi goodafternoon,
I think the problem is your thermostat is bad, because I had similar issue that the rpm would be normal and then rpm goes up by itself for a while without any warning. I got an accident because of this in the winter. Hope this helps.

When the weather is cold, while driving normally, the RPM will just automatically goes up but when the weather is warm, the car has no problem. is there a thermostat or temperature gauge in the car?


Sounds like a faulty temp sensor,giving a false signal to the cold start fuel injector. Normally at start up this will be obvious in a higher tickover rpm than when in warm weather. If it is doing it when driving along then you temp sensor could well be faulty, or possibly the injector itself,a bit like a carburettor choke on an old car.

When turn on the car in the morning, i accelerate and the revolutions up to 6,000rpm normal. In 3 minute when the car up the motor temperature to the normal operation, i accelerate and the revolutions up...


To begin with, if you are revving a cold engine to 6000 RPM, you are asking for a blown engine. Most OBD vehicles are equipped with a rev limiter that will cut off fuel at 3000 to 4000 rpm to prevent you from over-revving your engine and blowing it up. If yours is revving to 6000 RPM cold, then the rev limiter, for some reason is not working while it is cold. I have no explaination for this. The best thing I can tell you is to stop revving your engine so high when it is cold unless you really want to see what an engine looks like after is has gone off like a grenade.

Sluggish acceleration. High RPM, High Oil Pressure

RPM is over 400 rpm higher than it should be with no gas pedal.


Could be several things.. I would suggest replace the neutral safety switch, all O2 sensors and fuel and air filters, PVC valve and if needed plugs n wires..
The issue could also be a bad throttle body.. Should be a good idea to get it hooked up to a diagnostic machine - get the codes and then you will know more of what you are dealing with..

Have a great day !!

High revs and surges when driving.


The revving to 2000 then dropping the 1500 likely means that it is in "limp home" mode. When there is a serious problem, the car will put itself in this limited mode to avoid further damage, and to get itself back home without stalling (hence the name). Since it stalls, its likely that there is a serious problem with the fuel system, and the limp home mode will not help you any more since you keep driving it like that. 
As far as the problem goes, it could be just about anything. Almost positive it has to do with the fuel system, but could be so many different things.
Hope this helps!
