Please i need advise on the possible problem with the vibration i am experiencing 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.....

The problem is with the engine seats of your car

[color=#006600][/color] Its your engine seats it maybe 1 or two of it. Change it and it will stop. Do you feel the same vibration when your gear changes? if you do the engine seat is also the problem

my chairman your engine or the sit does not have any damn problem, the problem is the vacuum pump in the engine it is expected to supply more air fuel mixture in order to increase your engine power so as to be able to carry the extra load from the A.C . just take it to ladipo if you are in lagos for it to be changed that might just cost you about 3.5k. Hope its helpful.

Really bro you are diagnosing Vacuum pump for a car you haven't seen and tested. You also don't know the amount of vibration the car is producing or if the RPM drops below 800 when the AC is on. Your diagnosis can only be determine if and when you have seen the car and tested the vacuum pump if its faulty or not. The dude with the vibration people problem please do tread with caution

1, Check your air cleaner casing if it`s torn, if so change it.

2, Have your injection nozzles serviced, if dirty can cause the vibration

3, Check your MAP (Injector mouth) sensor.

The vacuum pump will cause irregular steaming on your car, so i doubt if it can cause it.
