i just brought a 96 with 196k on it yesterday and today we have to go somewhere and on the home we stop at a red light oil light came on then light green and gave it some gas it went off so we was close to been home it starting acting like engine going die but never did so i check oil when i finally made it home and check the oil it is full but i got the codes here

Looks like a great time to do the 60k maintenance list.

 

X2 !! 60k

My '96 oil light came on because it needed 15w40 oil, not 5w30....

 

From my expereience 5w is not heavy enough.

With that many miles on it, you better get busy with the 60K list and don't be surprised what happens. Hope you got it cheap, be prepared to spend a small fortune now.

 

my oil light would come on at idle on my '96. Turned out to be a bad, new oil pressure switch. Instead of ordering a new one from online, AGAIN, I bought one from autozone. It was the factory part, re-bagged.

 

i though i found the cobra a broking oil pressure switch and i change that out so i drove it to gas station and back.. when i got back home the oil pressure light was on again grrrr plus the oil smell like gas so that is my next guess is to do a oil change

 

Yeah....probably really old and broken down oil that was not the right weight anyway. I use 15w40 (Rotella) with a good filter and I bet if you do the same - the oil light stays away.
Then, new fuel filter, new 7mm (At least) wires and new plugs - and I bet you deal with the bulk of your codes.

I would completed the remainder of the 60K service anyway, but just those adjustments will show vast improvement.

 

Oil that smells of gas (fuel) indicates that the injectors stay open too long and the excess fuel passes down into the oil.
Pull out the ECU, open the cover and look inside for corrosion.
Tell me the condition of the ECU.
No use changing oil, plugs, HT leads, etc if there is overfueling. You just get to redo the oil change and new plugs over again.
PS: the injectors are hot (+12Volts) at all times and are grounded to make them open... so something is telling the ECU to keep the injectors open longer. Don't blame the injectors and go changing them just yet.
Running the engine with fuel in the oil will cause seal failure.
Does the car have a K&N air filter? I hope not! Oil from the filter damages the mass airflow meter, really $$$.
You can test the HT leads by running your hand over the leads while the engine is running, if you wake up in the emergency room, the HT are bad!
No, really don't do that.
An easier way is to spray a fine mist on the HT with the engine running and in the dark. The mist will let the spark jump from the leads to ground, thus revealing HT faults.

Play safe

ok i will try that after this post soccer dad but i know it went stay on at idle to blinking or fading in out and coming back

 

What these guys are saying about the oil is 100% true, these engines are hard on oil and if the wrong oil is used you will have problems.

Now because of your misfire codes I am betting you have gas in the oil because of incomplete combustion.
Change the oil, do a tune up and see what happens.
If the oil gets contaminated again its a cheap thing to re-do.
