Default Bonne doesn't like too much oil! oil overfill issues

I bought a used '96 SSe 6 weeks ago I had an interesting experience with adding oil...I put in about 1/2 a quart OVER and subsequently on the highway Bonne began to hesitate and sputter a bit if I pressed the gas anything but gradually. This was only happening at 50mph and over.

So I took Bonne to Wally World and had them change her oil. I watched the Wal-Mart people like a hawk because they are inept; I counted the oil being put in after the change and said "stop!" right at the 4 1/2 quart mark.

Bonne was fine again after this. I never had a car before that was sensitive to oil overfill.

On the receipt from Wal-Mart it says, "Pre Service Oil Check - CHECKED, Half Quart Low"

Beware of Wal-Mart gotta watch everything they do!

I always put in 5 quarts with an oil and filter change. Never had a problem like that.

My engine is the Series II. There is no question that having too much oil caused this problem I can't be sure exactly how much over but it showed on the dipstick covering the whole flat area above the hashed full mark.

I'm not sure I agree with the diagnosis either.

There are many here that overfill by about 1/2 quart and many use a slightly larger filter to soak up some of that overfill. To cause a problem..you'd have frothy oil where the crank was submersed.

How is there no question it caused this issue? I have been around 3800'* forever and have always slightly overfilled them with no issues..

You have another issue that will happen again in due time...

Its said to be a 4.0 qt without a filter change and up to one extra Qt with a filter change..

I always use 5 Quarts

Sounds to me like a bad plug wire or coil

My Bonne never had an issue with acceleration until I added the extra oil. It was doing it continuously from when the oil was added then was fine after the change. This all happened in 24 hours.

Time will tell! I'll come back if she hesitates again! I'm very confident she won't because there was such a clear, positive change in her after the oil change.

Check your PCV valve. There may be a link here. When was the last time it was changed?

I had some hesitation this morning with a high speed merge I was pressing it hoping to have it fail...so the traction control went off and the check engine light came on...I suppose it is the plug wires?

I'll get the code read.

Bonne sure did like having the oil changed though!

jr's3800 you are CORRECT!

I looked around the area of the coils this morning and there was an arcing noise, tonight I saw sparking on the plug wire 3rd down from the top on the 2nd coil pack. Touching the cap of this wire gave me a shock when I pulled it off there was a lot of corrosion inside.

Mostly I stopped the sparking by cleaning the wire (not shocking me now) but I fear the coil packs are bad on the 1st and 2nd packs, near the base of those two I can see blue light with the car running? I don't know if it is normal.

I think autozone sells coils for $25 I'm gonna try just the wires first.

So are the coil cases cracked? That will cause quite an ignition problem.
