The last few day I would start my car and it would run really weird. It would kinda sound like it wanted to die (at idle and driving) and sometimes it even did. But I just make it go and eventually it smooths itself out and all is good. but later it MIGHT do the same thing when I go to start it agian (sometimes it does it.. sometimes not I would say 6 out a 10 times)

 

plugs wires bad gas???? my car had bad gas and when i would start it would spit sputter misfire etc used some fuel stabilizer changed plugs problem went away

Crankcase Ventilation System Inspection/Diagnosis
Concern
Action

External oil leak
Inspect for any of the following conditions:

Plugged positive crankcase ventilation (PCV) valve.
Damaged or incorrectly installed PCV valve.
Excessive crankcase pressure.

Rough Idle, Stalling, or Low idle speed
Inspect for any of the following conditions:

Plugged PCV valve.
Leaking (damaged) PCV valve.

High idle speed
Inspect for a leaking (damaged) PCV valve.

Sludge in the engine
Inspect for a plugged PCV valve

 

It could be a lot of things. To add the list already stated I would say Sticking or dirty EGR valve making it not seal at idle.

 

Is your '95 a 3.4 or 3.8?

Rough, Unstable, or Incorrect Idle and Stalling
Step
Action
Value(s)
Yes
No

DEFINITION: Engine runs unevenly at idle If severe, the engine or vehicle may shake. Engine idle speed may vary in rpm. Either condition may be severe enough to stall the engine.

Check for incorrect idle speed. Ensure that the following conditions are present:
Engine fully warm.
Accessories OFF.
Using a scan tool, monitor IAC position.
Is IAC position within the specified values?
5-50
Go to Step 11
Go to Step 10

10
Visually/physically inspect for the following conditions:
Throttle body tampering (throttle shaft stop screw turned).
Restricted air intake system. Check for a collapsed air intake duct, restricted air filter element, or foreign objects blocking the air intake system.
Throttle body. Check for the following conditions:
Excessive deposits in the throttle bore and on the throttle plate.
Objects blocking the IAC passage or throttle bore.
Excessive deposits in the IAC passage or on the IAC pintle.
Large vacuum leak. Check for a condition that can cause a large vacuum leak, such as a incorrectly installed or faulty PCV valve or brake booster hose disconnected.
If a problem is found, repair as necessary.

Check for proper ignition coil output voltage with a J 26792 spark tester:
Clip the spark tester to engine ground.
Connect one end of a spark plug wire to the spark tester; connect the other end of the spark plug wire to the coil being tested.
Connect one end of another spark plug wire to the other coil tower; connect the other end of the spark plug wire to ground.
Crank the engine while observing the spark tester; a crisp blue spark should be observed.
Repeat the above steps for each coil.
If adequate spark is not present at all coils, replace affected coil(s) as necessary. Refer to Ignition Control Module Replacement .

Remove spark plugs.
Check for wet plugs, cracks, wear, improper gap, burned electrodes, or heavy deposits.
If a problem is found, repair as necessary. Refer to On-Vehicle Service in Ignition System.

Notice
Determine the cause of the oil or gas fouled spark plugs in order to avoid damage to the new spark plugs.
