My car is 1995PONTIAC Firebird 3.4L V6, burning oil is now very serious, to the number fluctuated greatly speed up the sound of the engine can not VIN: 2G2FS22SXS2215261

the HONDA Horizon (Isuzu wonder box)
what engine. exactly .?
3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4
x1 or G2?

floods, wot cranking cuts fuel and starts any flooded engine,
it's overheating that wins the First order failures rule sets.
nothing else matters. cure that first.! find cause! first.

sounds (im deaf there,lol) that smoke is out tail pipe end and dissipates fast and is not smoke but steam, , oil smoke smells like burning oil and lingers. steam smells sweet like burning Antifreeze.
AF steam is a blown head gasket or far worse.
do a compression test first to see if it's even worth fixing????
most are NOT. (unless free labor, sure)

first learn steam from smoke
serious , watch moms tea pot. see that steam goes away fast.and very uniquely , now watch burning oil.
remove dip stick, drop the drip of oil on hot exhaust manifold.
smell that, that is oil burning, and lingers.
this will last you a life time of blown engines..... just one look and bingo. (my instructor in 1965 did in front of class)

got oil in the AF/ CARBON chunks in same.
water in oil, ? pan, engine . milky oil.
rad leak down test fail? can be lots of reasons even a cracked block.or head. not just gaskets.

Most likely not. Those fumes/smoke are produced constantly by your engine. When it is running, the vapors are sucked into the air intake and burned with your gasoline. The PCV valve is designed to do this job but when the engine shuts off the valve stops drawing the smoke away and it just sort of hangs there until it settles.

PCV = "positive crankcase ventilation"

with an oscilloscope -- but if it is running ok then there will be no fault.

When you say "sputters at 2000 rpm" , are you referring to ANY time the engine is at 2000 rpm - meaning in Park, when you are just goosing the throttle, or in gear when you are accelerating, or at highway speed in high gear? If you are experiencing a "shuddering" in the engine at certain speeds/rpms - especially if these are speeds you regularly cruise at (long commutes at steady speeds), the problem could be in the Throttle Position Sensor (TPS). They have a tendency to wear unevenly if you drive a certain steady speeds. Eventually, the problem would progress to an engine code, but it may occur without setting the check engine light.

It's located on the bottom of the oil pan.

The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!

not good, but do not panic until you check actual engine oil pressure

that being said...take the concern seriously because the light turns on when oil pressure is less than 10psi

have you changed your oil recently?
did you use the correct type 5w20

have you checked actual oil level?
I have seen a lot of town cars that burn oil and you may actually just be low

Check oil level first
Check oil pressure second

if both check out then you have an oil pump problem or a more serious engine concern

keep me posted!

Check to make sure the radiator fan is coming on watch it for ten minute as it runs it should come on if it doesn't replace the fan relay or the fan coolant temp senson located on engine block upper area of engine.

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.

well take it back to you're mechanic and have him in stall a master oil pressure gauge and check teh oil pressure this will tell you if the engine indeed has low oil pressure or if the oild pressure sender is bad. also if it is rattling or knocking SHUT IT OFF you dont wana spend the 4-5 thousand to fix it im sure
