Hi, all! I just checked in looking for an answer to similar problems I've been having with my '92 240DL. Running rough, inconsistent idle, tends to quit running with any idle time. Pulling bat cable to reset seems to help, but not for long.
Getting the ol' 2-1-2 return code as well. I've had my fuel pressures checked and they're all good. Next step, I think is to change the O2 sensor, but my smalltown local jobber wants $200 for one (CDN, retail), so I ordered one last night on ebay from Global Automotive. NOS Bosch for $US18.00. Trouble is it won't be here for a week, and now to my immediate problem:
I have to go to a wedding this coming weekend. It's a 300 mi. round trip and, although Barby (the car) is running pretty crappily, I'd be willing to subject her and us (her humans) to the abuse in the circumstances if the permanent damage wouldn't be too severe. So question/opinion quest: What would be the problems I'm flirting with, other than possible plug fouling (I'll carry spare plugs) and oil dilution (which I'll monitor). Does this plan make any sense, or do I cancel the reservations and drop the wedding from our plans?
Any advice appreciated in this side-consultation. New O2 sensor will arrive next Tuesday - the day after my (hopefully) return.
tnx,
ps
