This is my third post about the '95 Pathfinder I bought at the auto auction a year ago.
When I bought it, it ran fine at speed but had a little engine miss at idle, for example at stop lights.
Right away I changed the air filter, fuel filter, spark plug wires and oil and oil filter. Also I ran Techron fuel injector cleaner though it and continue to do so from time to time.
It runs much better now with only an occasional miss at idle.
I believe the next thing to do is to change the spark plugs. I would have done that sooner but have been real busy.
Is this the next step to address the miss?
Is there anything else you would suggest? The mileage is approaching 200,000 miles and I think it is also prudent to change the serpentine belt, but that will be another post if I run into anything unusual.
I am concerned about stripping threads in the head. So finally should I remove the plugs hot or cold. Do I need to treat with any penetrant before I try. Should I just leave them in (i have no idea when or if they have ever been changed) ?
Thank you,
Richard
