Need to get the code(s) read on the computer to focus your problem search. Swapping things with new parts can be an expensive troubleshooting process.

    Misfires would certainly cause poor idling. Try replacing the spark plug wires. Contact Honda for information about the p1399 code. Disconnecting one battery terminal for a short while will reset the codes once you find the problems.

Why is my engine slowing down and rpm dropping


It is impossible to provide a proposed answer to your question without knowing the YEAR and MODEL of your vehicle.
That being said, your OIL light indicates either a deficiency of oil in the crankcase or an oil condition or delivery issue.

Oil pressure gauge drops to zero when car slows down, sometimes will go up when rpm reaches 2800, otherwise stays at zero, when shut off and turned on again pressure would be normal


Hi assuming the oil filter has not become blocked, it sounds like the oil pump is not working properly. Of course it could be something more simple like a faulty gauge, sender or bad connection. But assuming again that the engine is suffering from oil starvation, I would get it checked quickly before you seize the engine completely. Good luck!

Vibrations during idling


which engine.??? never post lacking engine ,here is why.
1.3 L G13B I4
1.5 L G15A I4
1.6 L G16B I4
1.8 L J18A I4
1.8 L BP-ZE I4
1.9 L XUD9 diesel I4

Ill answer in the generic and for GAS engines. only.
that is illegal RPM, the ECU regulates it to 800 all the time
that means the ECU can not regulate the RPM now, for many reasons.
and sure it vibrates too low, that is normal for all 4cylinders to do that.
no bad engine mounts never lower RPM to 600, ever.
they dont control idle speed at all.
the #1 reason for most cars to idle too low are:
1: EGR leaks, (clean it)
2: ISC stuck closed (electric idle speed acututor dirty) clean it.
3: gross misfiring , caused by bad spark or bad fuel mix.
4: low compression on 1 or more cylinders (real low) Do compression test at WOT. throttle.

I changed the engine oil, filter and spark plugs in my 1999 Volvo 940 (1996 cc). Upon starting up, the engine runs at lower rpm and "hiccups" at idling.


Engine stalls or RPM fluctuates at idle up and down.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

1996 VW Jetta with 2.0 engine. Dies when slowing from high RPM


Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
