Rather involved , Will require a full set of workshop tools including torque wrenches. I advise against it . But if you decide to go ahead buy a workshop manual and follow it to the last word.

Have your mechanic check the car for a leaking head gasket; in the early stages white smoke - coolant being burned - will show up; you would not see any leaks, as the leak would be INTERNAL; driving with a defective headgasket will for sure cause more severe damage to the engine!
thermo fan not cutting in /clutch fan faulty.
headgasket blowen...check for bubbles in the radiator if lots of bubbles then its a headgasket /cylinderhead problem
More than likely your headgasket has blown or may be low on oil get it changed and see if you have the same problem and if so have someone do a compression test or head gasket test
Look for a green male to male vacuum damper on the vac line.
It look like a mini inline filter.
Size is able 3/4" diameter X 1"
It's tapping off the main vac line.
If your engine has high mileage then blow oil can enter the vac line.
The green vac damper can get gum up with oil vapor and keep vacuum control device from operate at the normal setting.
====
You can use 70% rubbing alcohol and water to back flush the green vac damper.
Make sure you let it air dry before re-install.

You should change primary and secondary fuel filters to rule out fuel related problem.
Inspect fuel hose and clamps to rule out air enter into the fuel system.
Check for leaks around the primer pump.
This is your heater core leaking. One thing you can try is some of the stop leaks that the auto part stores sell. I would try "Liquid glass" as the heads on these are kind of delicate once overheated. This may also stop any other damage occuring(like leaking headgaskets). The only other fix is replacing the heater core.
Sorry, but there is no such thing. You sound like you are dealing with a common problem with that engine, which is the headgasket failure. No other way around this other than to remove the head (may as well rebuild it while you've gone that far), and install a new headgasket. Because most of these heads had been exposed to overheating, you should have the machine shop check for warpage and "adjust" by milling the surface height.
Be prepared to spend approx 1800 to 2200 for this job including the machine shops' cost (600-800) to rework the head.
be very wary as headgaskets often mean other problems,overheating etc i would find another car as this is not a job for the faint of heart, other problems may arise and then your stuck. why did the headgasket blow? get back to me if you need more help as i strive to be the best please rate my answer
