Question about 2000 Chevrolet Malibu

2000 Chevy Malibu- check engine light

Recently purchased Grandma's 2000 Chevy Malibu. Sharp car. Only 90,000 miles. Never exposed to salt (Tennessee). It sat (unused) for about 9 months, before I bought it, though...
During the trip from TN to OH, the temp guage started climbing, but didn't lose coolant. Once w/ me, in OH, temp guage rose & coolant kept leaking enough to cause low coolant light to come on. Before I actually recieved the car, my uncle gave it a quick tune-up. He flushed the radiator, changed the oil, replaced plugs and wires, and topped off the fluids.
The first day I had it, I took it to my mechanic, so he could look into the overheating issue. He noticed bad bearing in water pump. He performed some sort of pressure test, and discovered a bad intake manifold gasket.
He replaced the thermostat, intake manifold gasket, water pump, v-belt, radiator cap & hose, and changed the oil.
Since then (3 days ago), my check engine light keeps lighting. Codes pulled have been MISFIRE-CYL3, TPS-LOW VOLT, and EVAP SYS CONT. The only one that has repeated itself is MISFIRE-CYL3 (3 times, in 2 days).
I purchased the car for next to nothing, but have now spent just as much on repairs! I wouldn't mind putting a little more money into it, but don't know where to go from here!
Any ideas?

Have the DIS module checked and the coil pack for cyl 3. If either/both of those need replaced, have it done and have the codes cleared. Then see if it clears the others.

You may need a TPS (throttle position sensor) as well.

In a way it has a fail switch, the shut down was triggered by a program in the computer. I would suspect the thermostat stuck closed, suggest you replace it.

Dexcool does not cause leaks, but it should not be mixed with other antifreeze. Is it possible that the oil in the antifreeze is transmission fluid from a worn out radiator? The radiator cools the engine and the trans, and internally , the radiator may have ruptured?

What type of maintenance my car would need after 90,000 miles


There is no special service needed at 90,000 miles other than the normal Air Filter & Cabin Filter replacement every 30,000 miles. Inspect all drive belts and hoses. You do need to replace Brake Fluid every 3 years independent of mileage. At 110,000 miles replace the spark plugs on a 4 cylinder, 105,000 on a V6. Replace engine coolant at 120,000 or 10 years on both engines. Replace A/T fluid at 60,000 miles. On the V6 at 105,000 miles replace the Cam belt and Water Pump. The 4 cylinder has a chain that you replace when it is noisy or you cannot keep the engine in time.

If you take it to a auto parts store they can help you get the code out of your cars computer. This will not cost you anything and may help identify the probelm. I use Autozone and Carquest for my parts stores.

2000 chevy malibu there is a tapping sound when i


Most likely its just your lifters clapping as they make contact, until the oil starts flowing good through them, then it goes away. My car has been doing that for a long time. Never had any problems. The rods are pushed up by the camshaft, the rods push down rocker arms which then open the valves. The rods are round at the tips and sit in lifters that pump oil through them up to the top of the engine and then out onto the valve springs. If your car has a lot of miles you may consider putting a thicker oil, something like 10w40.
