Please i need advise on the possible problem with the vibration i am exriencing when i put on the AC in my honda car......it is usually strong when i am in traffic and generally on low fire.....i have tried increasing the fire and only reduced it back cos of some other issues....Also my mechanic have advised me to change my AC compressor which i spent money doing and still the problem persists...Any suggestions from fellow Nlanders or personnel familiar with this kind of issue? It will be appreciated.....

Engine mount/ Engine seat. Check them and probably get a replacement

I have changed the engine seats long ago.....it reduced the vibration though but its still vibrating

Mostly if it is on gear......

Engine misfire more pronounced with ac use at idle, check ignition system?

@oyibomoses
why should you just assume that it is the plug that is the issue? are u a magician?
Oga OP, do a scan on your car only then can u be sure.My take on this is that it could be a cylinder misfire or random multiple cylinder misfire which could be a symptom of faulty spark plugs or the Coil.

my 2cents

Thanks yll for ur contributions...i will try these remedies out and see what the result will be ....

4 possible problems.

1. Bad plugs/Engine misfire
2. Engine seatings
3. Gearbox seatings
4. Wrong Ac compressor was installed.

Either of those is most likely your problem.

i had a similar prob on ma honda baby, bu the prob stopped by itself after series work by auto mechanics; changed the plugs, serviced the injector, cleaned the nozzles, even drained n cleaned the fuel tank all to no avail. Decided to manage and drive it that way.
One day my car got stuck in a ditch, as i tried to speed off through the ditch my engine shaked so hard that i was scared. Finally, i succeded in driving it off the ditch bu to ma suprise the prob it was having before ve stopped..
To me, i think the engine mounts was the cause of the prob.

It happend with my 2003 EOD. You need to change your Plugs. After changing your engine seats and it still persists, then the next culprit is your plugs.
