My Vitara Vibrates just above Idle and worse under a load. I took it to a mechanic and he changed the timing chains, tensioners and guides. Then he replaced to motor mounts with aftermarket parts. The problem still is not fixed. Do you have any suggestions on how to fix it.

It shouldn't rattle , it may have stretched a bit over time or the tensioner has moved. Yes tighten it up a bit but if the car is or starts to miss a bit you'll need a new timing chain. I wouldn't put it off if I were you.
It may have stretched, but you would have known if it had stretched more than the tensioner could make adjustment for at the time the front cover was off. When you say "left bank", are you meaning the LH bank when you look into the engine bay (which is actually the RH bank), or do you mean the LH bank as in the LH side of the car? As it sounds like only the main chain was replaced initially, my thinking is that the 2 other chains and tensioners also have some wear. The RH tensioner is the only one you could possibly get an extra click out of the ratchet without pulling the entire front cover off again. You do have to remove the RH rocker cover, and with a fabricated "hook" pull the tensioner block upwards. Listen for a click (or clicks) and make sure there is no slack on the top of the chain between the sprockets. This tensioner can be starved of presurised oil if the engine is sludgy, and doing the above doesn't solve the blockage but will quieten that particular problem. Anything else will require the timing cover to come off again.
I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )
i had the same problem. had a knocking on the engine and let the vehicle sit until i had time to look for the problem. my unknowing mom took the car without permission and the car broke down on her. as it would turn out the upper timing guide rail broke off and damaged the cam gears and broke the upper timing chain along with damaging both the right and left lower chain guides, and the tensioner was also damaged. i would recommend that u inspect the lower chain to make sure that everything is good.
When the timing chains stretch( and they do!) they can cause the 22re to stumble intermittently. Have trouble starting, misfiring, and even some trouble codes But first check your engine for codes You can do this by jumping TE1 and E1
If you have codes we can go from there. You should pull your valve cover and check you timing chain tension, it should be very tight and not loose. if it is loose it is most likely time for a new chain and/ or tension and guides. I always replace them as a kit. Keep in mind that if the chain is worn it will get progressively worse until the engine will not run or the chain will wear in to the water galleys behind the water pump on the timing chain cover. sorry man.
