Hi, yes, ... my car just started having the RPMs to go up and down while I am driving...

I have already rebuilt the front top of the engine.. the converter, the camshaft, the spark plugs the front and back sensors of the converter, oil change, wires.... you name it I did...The code says converter sensors.. I did that it also says a vacuum leak... I don't know what that means.. But i am thinking it is the AIC < i seem to have all of those symptoms on the car. Please help?? THANK YOU SOOO MUCH AND HAVE A BLESSED NEW YEAR! Shellee :)

Does it quit all of a sudden? I have a 99 Cherokee that developed a stall problem... totally random and unpredictable... difference being I discovered I could at least get it restarted by replacing a fuse it was blowing.... eventually was discovered to be an exposed wire making contact with the firewall.

SOURCE: i have a jeep grand cherokee laredo with the 4.0L

It is most probably the crancase ventilator gizmo. Go to the Jeep dealer or other reputable mechanic to repair. I did and it cured the problem. It cost me about $120 and it was well worth it.

SOURCE: 03 nissan altima turns off

There was a recall notice issued last year (or maybe even 2007) for this particular problem. Take your vehicle to the dealer immediately and they will fix it and reprogram the computer to stop this problem.
While not dangerous in itself, it could conceivably cause an accident.

2005 Acura MDX leaked transmission fluid out of breather oil on top of engine

oil out of the breather is an indictation of excessive oil
if it drives as would be expected, there is nothing wrong with the transmission so move away from the mechaic who stated that ir was "fried"
at 60 mph the rpms should be in the vicinity of 3000-3200 rpms and go up about 250 rpms for every 10mph over that
have the fault codes read or take it to an accredited transmission professional shop and have the bands and clutches adjusted

Hi I'm Peter. I'm not quite sure if you are asking if a car will start with no oil in the engine or if the engine was ran with out oil until it seized up. Is this an engine that was just put in? If it was rebuilt and installed was running then froze up I would suspect that the person who rebuilt the engine made a mistake somewhere causing the engine failure. If you are asking that if you drained all the oil out of an engine would it still start and run the answer is yes. There will be a residual oil on all the metal components that would allow the engine to run for a while but eventually it would heat up from friction and seize. If you ran the engine low on oil possibly from it leaking out somewhere and the engine will no longer start then you just seized the engine and it will need rebuilt if possible or replaced.

Top up radiator

Darcy, there isn't a typical radiator cap like on other cars. You'll have to fill it into the overflow reservoir.
Fill it to the MAX line. If you are doing this after a full flush, make sure you bleed the air out: After filling the reservoir tank, start the engine, drive for a few miles(make sure you get pretty high RPMs a couple times). After the engine cools, check the coolant level again, fill it back to MAX.

Yes, I have a mini cooper 2003 and the RPMs just started to go up and down while i am driving... Could it be the AIC? Or the timing belt? Could me not EVER replacing the ****** filter cause it? THANK

could also be the intake manifold gasket. While car is running, spray engine cleaner or brake cleaner directly onto the intake manifold gasket. If you hear any difference in the idle, the gasket is gone. Also spray all vacuum hoses. Good to rule that all out before you spend a bunch of money on not needed parts. Mine was gone and replaced 2 weeks ago, same symptoms, and I didnt spend a fortune diagnosing the problem. Let me know how you make out

My 1990 Camaro with an AC Delco rebuilt 1989 Blazer engine. I have replaced all the sensors except the MAP sensor checked the ignition module located in the distributor is fine. Replaced the cap and rotor...

You are going to have to get the old O2 sensor out of the manifold and replace it. The computer uses it to tell how much fuel is need in the engine to keep it operating.You could also have a vacuum leak which will confused the computer, spray some brake cleaner around the top of the engine manifold to see if the RPMs change, if it does you found the leak. If the engine revs up & down in park, you don't need to drive to find the problem, you have to fix that problem before you put it in gear. Try the easy things first, then go on to the next.
