whenever i turn on the A/C, load comes into the engine and you can feel vibration on the car.

is it an engine problem? (engine cant take the A/C load) or something is wrong with the A/C ?

No expert but I’ll speculate & take a stab at it. I doubt your engine is at fault. Probably not the ac pump either or you’d might be getting screeches from the belt.

AC pump puts a significant load on the motor. Mine dogs at Idle for a second when the AC is turned on but, the pops back up to a normal rpms.. I believe the AC also shuts off under heavy acceleration.

My guess is that the speed up (at dle and) cut out at heavy load circuit is amiss.
