2003 Mazda6, after the engine has warmed up, when I'm in gear and at an idle it will periodically drop between 25-50rpms and then return to its normal idle. Why?


Engines rarely idle at the same rpm all the time. Its normal for changes to occur, especially small ones. Too many variables that can effect such a small change to list. Its no an issue to worry about.

You need to check for intake vacuum leaks. Also did you have the battery disconnected before repair, if not disconnect the neg cable for 10 minutes to reset system to base settings.

The tachometer shows 900 RPM on idle position but as i put the car in gear and release the clutch the RPM drops and u have to race the car manually through accelerator pedal.recomend the diagnostics a


The engine does not need to be raced when cold

The vehicles computer will adjust the idle according
to how the manufacture programmed it

After about one mine or so, the idle on most vehicles
comes down to approx 750RPM, generically speaking

When you put the car in gear,assuming it is an automatic,
the rpm will drop a 100 at most & may be adjusted by the
computer, just as it does when you put the A/C on. That is
to compensate for the change in engine load

You should be waiting for the rpm to come down to 650 to
800 & then a couple more minutes for some temp to come
up, before driving off. In cold weather wait at least 5 min or more

I think your vehicle is not working correctly, or you not explaining
it in a way I understand what answer you want

My car slams when put into drive. is it the idle


Yes, sounds like the idle speed is too high. If you keep driving like that, you will fry the torque converter / turbine. Since idle is computer controlled, you will have to take it for service tune up. There is one possibility that the rich, high rpm idle used for cold start is not disengaging properly after the engine warms up. Air conditioning will raise the idle speed by a couple hundred rpm, so avoid using it until you have the problem fixed. BTW.....warm engine rpm in idle, and neutral should be around 700-800. Anything over 900-1100 will result in a hard shift into 1st gear and dragging at stop lights.

1992 chevy blazer idols too low when engine is cold it idols around 800 rpm but when it warms up it drops down to around 400 rpm n alittle lower when i put it in gear


The problem is in the idle air control motor. It is mounted on the throttle body with two bolts, you can pull it off and make sure it is not caked with carbon also check where it mounts on the throttle body and make sure it is not caked with carbon.
