I consider myself lucky that so far I have never had any real engine trouble so I have never needed to do a whole lot, just maintenance. However, my day of reckoning has come. I had spilled pop on to the shifter (I don't think this caused my issue I describe farther down) a couple of days ago and the very next day I had the center console taken apart to clean it and put it back together. Once I did, I started it up and test drove it just because. Well I noticed that when I would stop there would be a small but noticeable stutter to the engine and the car would shake a tiny bit, it goes away completely when I'm driving at any speed. More detailed info below to help you help me.
- Does it in overdrive, drive, and reverse ( I didn't try it in 1st)
- Does NOT do it in park, or neutral
Here's somethings I have done recently so you are up to speed.
- I did a differential fluid change in early August and had no problems
- I changed the spark plugs two weeks ago with NGK G-Power Platinum, gapped properly and torqued to spec. The old champion plugs I pulled out were gapped at 0.045in. (WAY below spec which is 0.054in.) I had a small issue with getting the plug wire on one of the new plugs but I figured I did get it because when I started it up after I changed em, the car ran perfect right after I did the plugs
- This stutter is not causing a CEL and the car does not feel down on power
I am going to check out the engine bay tomorrow morning and see if anything looks out of place im just putting this post up now so that if I cant find anything wrong its already up
I will keep you posted and I am infinitely grateful for any help or suggestions you guys have
