A few weeks ago, I got a code for a mis-fire (cylinder #4) in my 2000 Nissan Altima. I have been so busy with work and fishing, I had my mechanic look at it. It ended up just being a bad plug wire, but he removed the fuel injector and inspected that before he found the wire problem.
Ever since he did this, the car has had a "stumble" when you first begin to accelerate. A few weeks go by, no improvement.
I pulled the plug in cylinder #4 and it's white and clean....looks way lean. The others are tan.
So last night, I had an hour to burn, so I pulled the same fuel injector in #4. The first thing I notice, is the o-ring that the injector sits on inside the intake/housing has a rip in it...but it's whole. It's all there. Then I notice another half piece of o-ring sitting down into the port that the injectors sprays gas in!!! I found a really long pair of skinny needle nose pliers and I pulled it out.
Car runs perfect now.
I can't wait to talk to my mechanic. Idiot.
