Miss under acceleration, dies at idle, sluggish accelleration

[DangerWRobinson]

Hey Guys.

I just bougth the car two days ago and it was fine when I drove away, these symptoms just started yesterday. I've searched, read, and looked around a little but no luck.

Symptoms:
1. When driving, the car will die when rolling to a stop. It always starts right back up.
2. Has a miss down low when I rev the engine.
3.The rev's climb VERY slowly.
4. Oil covered spark plugs.

Tuneup stuffs:
1. New valve cover gasket and tube rings.
2. Changed spark plugs.
3. Chagned the PCV valve.
4. Oil and filter change.
5. Air filter change.

After reading some, I pulled the o2 sensor plug and the missing/dieing at idle still persists so the o2 is good. Any other ideas?

I'm thinking change the plug wires but they look pretty new and seat nicely on the plugs. Maybe clean the IAC, but that wont cause a miss. I think it's something ignition related. TIA for any input!

DWR.

BTW, is a 91 LX. F22A1, manual trans, all stock.

if your tachometer seems like its "jumpy" then it could be a possible ignitor issue.

The new valve cover gasket probably won't fix your oil in your spark plugs. Its the rocker arm O rings that are most likely leaking into the spark plug chamber. Once those are fixed, that should take care of the low RPM sluggish acceleration. If there's anymore issues after that, feel free to post up the symptoms.

truth be told, you might have dead cylinder. do a compression check. all cylinders should compress at 110 to 125 psi.

The tach seems smooth. I dont think it's bad, but if everything else is good, I will check into the ignitor. How do you go about changing the rocker arm o-rings? I believe they came in the kit with the valve cover gaskets and boot rings.

IDK man, it seems to smooth out and fire when the RPM's go up. I can borrow the gauge to check compression tomorrow.

Any other ideas?

Well, I have a LOT more checking around to do now... the car seems to have dropped ignition from another cylinder. It's now BARELY running and died on the way home from the hospital today.

It will not start back up. WTF.
