Don't think there's anything wrong with it. That's pretty normal for mine. If it's unusual behaviour for your car, check your coolant level. I almost ran mine dry last year and found in the days leading up to it that my idle revs were sitting around 2000 once the car heated up. If it turns out to be that I can give you some real handy tips for changing your coolant and flushing all the junk out. Much cheaper than a mechanic and good if you have a spare hour.

The throttle position sensor has an idle switch in it that tells the car's computer that the throttle is positioned at idle. If the idle switch sticks in the idle position, the computer will not allow the engine to rev more than 2500 rpm. In your case, I think the switch is stuck.

First, see if you can get the trouble codes to come up. Rig a jumper wire and jump between the "T" terminal and the "E1" terminal in the car's "Diagnostics" box. It is a small black box on the driver's side of the engine compartment near the battery. Open the lid and on the inside of the lid it has a map of the terminals.

Once you hook up the jumper wire, turn the ignition switch to on but do not start the car. If there are codes, the check engine light (orange) will blink the 2 digit code. It blinks the first digit, pauses, then blinks the second digit. The code for the throttle position sensor is code "41". That is, four blinks...pause...then one blink. If this code comes up, change the throttle position sensor. (If there are no codes, the check engine light will steadily blink once per second until you turn the key to off.) Don't forget to remove the jumper wire when you are finished.

Why does the engine revs drop too low and sometimes stalling when I engage any gear?


This can be either an engine management issue (bad idle air control) or a transmission issue if an automatic trans (torque converter lock up problem). Idle air control can often be cleaned so = cheap fix. Trans problem not so easy.

Rev counter jumps whilst idling and then engine cuts out


Your problem sounds as if the thermo sensor....which controls the air fuel ratio when engine is cold....is faulty. It is a common fault on this model.
This is not an expensive part, and takes only a short time to fit.
Good luck

Honda Civic 2002 1.7, when driving the car, it's seems like the car switches off for a split second and the engine management light shows for the split second. The rev counter drops. When cutting out...


Check all the wires. Especiality the ground wire.
Battery terminal.
And grounds mounted on the intake.
Normally when no codes are present, Is a lost of electrical power.
