I have a 1995 Pontiac Grand Am GT w/ a 2.3L Quad-4 engine. I recently
changed the oil, and used Pennzoil engine flush to try and release
what sounds like a sticky lifter (kinda worked). I added the engine
flush to my old oil and ran the engine for 10 mins, then did the oil
change to Mobil 1 synthetic. This was about a week ago, and this
morning i started up my car and it was coughing and sputtering and
just not sounding all that happy (idle or throttle). I removed the
air filter to see if the engine was being starved of air, but that
didnt change anything, so i reinstalled it. Next, i noticed that i
was low on coolant, so i topped that up (there didnt appear to be any
puddles or leaks, but i still had to add about 2 quarts). I didnt
expect that to do anything because a choppy running engine has nothing
to do with coolant, and it didnt. I had a quick peek at my oil on the
dipstick for argument’s sake, and it was very cloudy/murky. This
worries me. The rough idle was all but fixed after i removed the
spark plugs and re-gapped them to spec (they are being replaced tonite
b/c they are pretty shot). But the new synthetic oil going cloudy and
a low coolant levels with no visible external leak confuses me. Also,
the plugs were pretty wet with some fluid, im not sure whether it was
coolant or oil.
Sorry about the long post, but can anyone offer any help?
