ASR Light
Hello guys, posted a few threads about this issue but never got any check light, until now.
It started a few months back when my 500 started idling rough, surging, and longer crank times on colder mornings. I recently replaced my EZL/ICM that seemed to just have gone bad and may not be related.
Replaced coils, caps, and rotors. Wires and sparks are fine. After all this the problem ensued, so I finally took it to MB. They stated my fuel pumps were bad, two new Bosch pumps later and problem persists, I must say it does seem to run a little better w/ the new pumps.
Well today I got an ASR light, no limp mode but its intermittent and just drove 40miles w/ no recurrence. I am taking it to MB on Monday or Tuesday but was hoping for some feedback. I know at one point there was a code for throttle actuator, no check light though and on some records I see a new one was replaced for $1,250 about 3-4k miles ago.
I luckily have a few other cars I could drive but this one keeps calling me to drive it, so I need a fix asap.
Any thoughts???

ASR
I Just replaced my battery with an Interstate MTP 93 after bringing my 93 500e out of winter storage. Changed plugs,caps, rotors & wires and 3 days later car runs great and the annoyingly intermittent ASR/limp mode light no longer comes on. Don't know how old you battery is but that may be a place to look.

Think my throttle body is sticking, def worse on cold morning start up for first mile or two then gets better. Never had the ASR light until the other day and had this issue for a while now. My battery was reading 12.18v when off, so it was up for replacement anyway but still have delayed crank. Any other suggestions are welcome!
