Ten days ago+-(100 miles ago) travelling at 70mph, cruise on, the engine skipped a beat, like the fuel shut off, the ignition failed on all cylinders, or there was water in the fuel line. It was a split second event, a hiccup.
A week later it happened twice in 2 minutes, same circumstance, hiway, cruise on, 70-75 mph.
Next day it happened coming off a traffic light after I exited a freeway.
Yesterday, it happened again on the interstate, at 70mph, and then actually stalled at a traffic light a few minutes later. It restarted perfectly.
Now I have a CEL on the instrument panel.
This vehicle runs exceptionally well, shifts smoothly, no heating/cooling issues, no hesitation on acceleration, nothing to indicate a malfunction like this. It's not a single plug or wire type of miss, it's a system wide failure.
It's just a split second blip, like a miss or a tug, but it obviously is becoming more frequent. Occurs after 3-8 miles of driving.
The second time it happened I thought maybe the tranny was hunting for 5th gear, so I added a 1/2 quart of tranny fluid thinking it was possibly low. That didn't solve the issue. (Thank you Benz for eliminating the tranny dipstick!)
Has anyone else experienced this sorta' hesitation?
I've spent over an hour researching this on the forum, but nothing came up similar to my symptoms.
107k miles on the vehicle, it's a sweet ride, not a beater.
Could a wonky wheel sensor tied to the ASR cut the fuel momentarily? If I were to guess(and I am guessing!) I'd say it is an ignition issue rather than a fuel issue. MAF in very early stages of failure?
Now how do I clear the CEL? I can't find a link on that.
