So I have this 1994 E420 with 136000 miles that has an intermittent ASR Light. How intermittent? Welp it seems like after the code is cleared it will operate fine for the next 100-300 miles of constant driving, then the condition occurs again. I pull the codes and find there is only one...06 ISC the vehicle goes into LimpHome mode when the light is on. I have done a search on this site and found some great information. I checked the throttle cable for wear, I checked the brake light switch which appears to be operating properly, TPS sensor seems to be working properly when monitoring it with my meter. All signs point to the ETA but I was looking for a bit more confidence as this part is close to $1000.

Any suggestions?

Thanks in advance
