1993 classic wagon check engine light and turn signals

My new used 1993 240 classic wagon is trying to humble me. It has numerous issues and when I fix one, another crops up. First, the headlights would not dim. I replaced dimmer relay and cleaned terminals on light relay. Then,dimmer worked, but the formerly properly working turn signals went crazy. Turn signals work, ( sort of ), with lights off, but only left one with lights on.

Car would idle rough, sometimes dying at intersections. Replaced throttle body with a cleaned 89 throttle body. Now idles smooth, but a day later check engine light is on and car acts like it has a fuel, or ignition problem. It has not stranded me, but it surges and acts intermittently like it is fuel starved.
Any ideas?

    Just a wild guess, but remove the shroud from the steering column and see that the ground wire is connected ( on the left side, I think). No real idea on the throttle body. What do the codes say ? Otherwise, leak at the gasket ? Accordian tube has a new hole ? You could try cleaning the '93 throttle body and reinstall it.

    My apologies to Art - What's the difference between an onion and an accordian ?
    No one cries when you cut up an accordian.

      Rough idle problem solved. I finally did the obvious, cleaned the old original TB and re installed. The TB has two adjustments, which I found out are VERY important. Now, check engine light is off, and car idles great. Thanks.
