1990 Nissan Sentra GAI6i engine breaks timing guides

Have you checked the oiler supply to the timing chain and the chain tensioner Just a thought. The guides usually only break from the lack of tension on the chains.

My 1990 nissan sentra has a noisy timing chain when running idle.

Your timing chain tensioner is using oil pressure to stay tight.Could be your oil pressure is so low at idle the tensioner just can't stay tight.At the next oil change you could go for a thicker oil and see if the tensioner keeps the chain tighter at idle.

Vehicle started sludgish after cranking once during the weekend

By now I would guess you have replaced the battery in the vehicle. Batteries always struggle during winter if they are getting old or run down after a lot of short runs and use of the heater blower, windscreen wipers, electric rear window heater and headlights.
Nothing beats a garaged car for being easy on the battery........and giving it at least a 10 mile run every weekend at speed keeps the condensation out of the engine, oil and exhaust systems.

Why a vehicle hesitates when going a speed of 65mph?

is it an automatic transmission? if so check the fluid level, that (MIGHT) take care of it if its low for the high speed problem but I think you have a fuel problem, check air filter if dirty change it then change fuel filter then get some injector cleaner and put into gas tank and run a full tank of gas out if that don't work then you will have to find a auto shop that can do code reads on that old of a car, also check your spark plugs make sure there in good shape, after you do that stuff and if its still not running right holler back and give me more details on everything it doing

90 nissan sentra 5spd manual wont go into any gear with or without running or clutch engaged. why?

The clutch isn't working correctly if you have to go through all that to get it into gear. You can check the shifter rails on top of the transmission, but that takes removal and dis assembly of the top cover on the transmission.
