I am pulling my hair out trying to figure out what is wrong with my car and was wondering if you could help me out.
About a week ago the car started acting like it was missing, I figured that I had gotten some bad gas or what not. Week went by and it only got worse. It has a really lumpy idle and jerks and sputters below 2k. If you unhook any of the plug wires at the distributor it does not change the idle, if you plug it back in the idle smoothes out and the car runs good for a little bit.
I have changed the following.
Plugs
Wires
Rotor
Distributor
Ignitor
Coil
and one of the O2 sensors.
If you could point me in a direction of what to look at I would be very thankful.
Car is a 92 Sc300 5spd if it helps.

I was having the same type of problems. Went through the test of Taking off one coil pack (ignition coil) and the other. Problem ended up being a MAF sensor went bad.

Let me know if this was your problem as well.
