Hi. Wondering if anyone can point me in the right direction here. I was driving my '93 100CS down the highway tonight, running great as ever and all of a sudden the check engine light comes on (several other lights came on too), flashing and clicking and the engine cuts out. I quickly pulled over, popped the hood and found nothing obviously wrong or out of place. I hopped back in, tried to start it and it fired right up. I drove to the next exit, got under some light for abetter look...again, nothing obvious. I drove the remaining 50 miles home without incident. Any ideas of what to check? I want to nip any problems before my next long drive. Thanks very much!!

o2 sensors.. How fast were you going? My CEL usually goes on at like 80 and then turns off and turns back on and then shuts off for the rest of the trip..

92-100S

If clicking is under dash, it is likely the fuel pump relay. This seems to be a semi-common problem. Engine shuts off under heavy load. I had this problem for a while. A new fuel filter, and possibly even a new fuel pump could be needed. How old is your fuel pump/filter?

must have been some relay. i never had any problems.
the engine shut off always happened when i drove on the interstate at a constant speed. driving with the cruise control on fixed the engine shut off problems.
when i drove different speeds on the interstate i didnt have the problem.
hope this helps

... especially if you had a lot of dash lights going off at the same time.
