I don't post often. Most times when I have an issue with my car, I search these forums and find the exact answer. I've repaired my climate control, replaced my LCM, dealt with air bag issues, etc etc all based on what gets shared here.
You guys are awesome.
But I've got one that I can't seem to find a result for:
The car (2004, 106k, bought new, bone cold stock) is studdering/shuddering/cutting out or something at given rpm/speed ranges.
First noticed it on the highway with family in car. When headed up hill (in OD) at 1,600 - 1,800 rpm's it was acting like a pretty bad miss. Pulled out of OD and did same thing. Tach appeared to be rock-steady during the events.
Back in town, does same thing around 1,100 rpm rolling about 35-38 mph. From a steady pace, slight acceleration will cause the symptom. Also a change in grade with induce it. Does it at same rpm range in OD, D, and 2.
Changed plugs (looked good but were ready) and had trans fluid replaced (did the in-line fluid replacement machine process). Plugs lessened the issue immediately. Do not like the way the coils plug onto top of plug. I was looking for the satisfying click doesn't look like they are made that way.
Fluid change did improve overall transmission feel (think it went 30k since last change) but can't say it improved anything.
Did discover next (now alone in the car) that full on pull from 60 - 90 yields what feels like a slight, inconsistent miss.
I'm thinking ignition or spark or some obscure sensor somewhere. Hoping and feeling the transmission is good. My next steps (since it needs to be done anyway) are to change the PCV and fuel filter.
Looking for the simple stuff. Ideas anyone?
Thanks, Tom
