The Check engine light (yellow light) comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system u will seldom feel the car engine run any different, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

Engine idle revs high when in park or nuetrol. When driving ckek engine light is on off intermittinlly, a loss of power.

Always check for trouble codes when the check engine light turns on during engine running. After repairs are made, a scanner can be used to erase the codes.

It sounds like a fuel problem, so you would need to have the fuel pressure tested. This will verify the fuel pump and fuel filter are not the problem if the pressure is correct.

If the check engine light is on, you need to check the computer for trouble codes first.
The idle speed is computer controlled by the idle air bypass valve. The valve can get gummed up, and so can the throttle body.

My 95 tahoe has an occasional ticking noise, loss of oil pressure at idle and loss of power

Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.

Your problem could be at the fuse panel. A cheap fix is to get some stranded wire. Small gauge, like 24 or 32 gauge. Cut small pieces and strip the ends and put them down in the fuse panel where the relay goes. Then put the relay in. If this doesn't cure the problem, look to the throttle body plug. best to replace the plug. If the wire woks for the panel, Leave it or replace the fuse panel.

My car sometimes revs up and down a little bit when parked after long drives and now when i drive it feels like it cuts out and loss of power. Its been getting worse every drive.

If the idle seemed to go out of control further then the issue may be with the idle air control valve, it may be dirty or may have gone bad. Check also the fuel filter and loose wires and vacuum hoses.
