What do i need to be changed it stalls when pushing on the brakes and plus the idle.


i need a little more info, 2 things could be the problem, first you could have a bad brake booster causing an extreme vacume leak which could stall the engine, or at least make it run very rough and stumble when brakes are applied, the other thing could be a low batt, when appling the brakes the brake lights will come on causing a voltage drop to the engine causing it to stall, whoever the condition would drain the batt to the point that it probably wont have enough power to restart the engine, if this is the case you would also need to check the alternator for charge rate easy enough to check hook a voltmeter to the battery with the engine running it should read at least 13.5 volts up to but not exceeding 14.9 volts

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

I have oil pressure until i stop , then it drops to below 10 psi


Increase the viscocity of your oil. If you're using 10W30, go to 10W40. If you're using 10W40 switch to 20W50. Don't use single weight oil.

Have the oil pressure tested with an accurate mechanical gauge. often the sending unit goes bad, but without testing it could cost you an engine before you find the problem.
If the mechanical gauge shows same low readings, you have internal engine wear (likely worn crank/rod bearings) Then, it's your decision on whether to drive it till it expires, repair it or buy a new vehicle.

Engine knock...


Oil pressure might actually be a bit high for idle. High or low oil pressure in an older engine tends to be indicative of some serious issues. Oil pressure that is too high tends to be a clue that you have serious carbon build up. That aside, have you tried running a higher octane fuel, or perhaps adding an octane booster to your normal grade? Pinging can become knocking in a badly worn engine. One recommendation: At your next oil change try substituting a quart of marvel mystery oil or lucas engine oil treatment in place of one quart of your normal oil. Both have some pretty good track records for helping to free up sticking valves and break up carbon in older engines. I'm an old timer myself, and I personally swear by Marvel for older engines. There is no "rebuild in a can" but Marvel comes close. Give those a shot, let me know what happens.

Idles rough when coasting


Have you checked all the vacuum pipes around the top of the engine.?
It`s not losing oil pressure, it`s just about to stall when the oil light comes on.
Listen for a hissing noise under the hood.
Vacuum leaks can cause real problems with the inlet manifold pressures.
Good luck.
