Vibration

[Wasa]

Dear Experts,

I have a small vibration in my AE 100/auto car. I appreceate ur valuble recommendations.

I had to replace its distributor & ECU recently. (same modle recondition ones used). After that I notice small vibration after engine hot & AC on. Even when head lights on, this is noticed. No vibration when above electric items off. Here the idle speed just after start in the morning around 800 rpm & reduce to around 600 when hot. When AC or other electric items on, further reduce to around 500 rpm & start vibration in any gear position (with no accelaration). When they off, rpm increase & vibration disapear.

I would like to know what the exact problem & how to fix it. And any good garage capable of doing this kind of repairs.

Thanks.

Get you're cars alternator & alternator belt checked. They may need to be changed or serviced. Also it wont hurt to get the car's earth cables looked into as well. But before all of this I'd start with checking the battery's voltage output at a battery shop.

sounds a retarted position of the distributor since you said it was changed recently. Ask the mechanic to check/re-adjust the distributor position and idle up valve/motor in the throttle body.
