Here's the codes. . . .

for a 140.057 engine, 92 thru 95:

6 - Idle speed control faulty
38- Not used!
41- Left intake air temp sensor: open or short
49- Data exchange fault between left LH-SFI ignition control module

You can reset them by using the procedure on my page MENU#2 called "erasing DTC memory". Remember that you have to bring each code up and within 20 secs perform the reset procedure FOR EACH DTC.

If they come back, try swapping LH modules and see if the DTCs shift.

FYI, here's all of the codes:

1 No fault found
2 Right oxygen sensor faulty
3 Lambda control of right LH-SFI control module faulty
4 Air injection at right cylinder bank faulty
5 Exhaust gas recirculation of right LH-SFI control module faulty
6 Idle speed control faulty
7 Ignition system for right cylinder faulty
8 Right engine coolant temperature sensor, circuit open or circuit short
9 Right intake air temperature sensor, circuit open or circuit short
10 Voltage at mass air sensor too high/low
11 Tn-signal (rpm signal ) at right LH-SFI control module faulty
12 Oxygen sensor heater of right oxygen sensor, circuit open or circuit short
13 Camshaft position sensor signal of right ignition control module faulty
14 Intake manifold pressure at startup (in right ignition control module) too low or too
high
15 Wide open throttle position information faulty
16 Closed throttle position information faulty
17 Data exchange fault between right-hand control modules LH-SFI ignition control
module electronic accelerator
18 Right adjustable camshaft timing solenoid circuit open or circuit short
19 Right injector circuit open or circuit short or emission control system adaptation in
right LH-SFI control module at limit
20 Vehicle speed signal missing
21 Right purge switchover valve, circuit open or circuit short
22 Right camshaft position sensor signal faulty
23 Intake manifold pressure(in right ignition control module) with engine running too
low/high
24 Starter ring gear segments faulty
25 Knock sensors or right ignition control module faulty
26 Upshift delay switchover valve, circuit open or circuit short
27 Right engine coolant temperature sensor deviation between circuit 1, and sensor
circuit 2.
28 Right engine coolant temperature sensor (engine coolant temperature change
monitor)
34 Left oxygen sensor faulty
35 Lambda control of left LH-SFI control module faulty
36 Air injection at left cylinder bank faulty
37 Exhaust gas recirculation of left LH-SFI control module faulty
38 Not used
39 Ignition system for left cylinder faulty
40 Left engine coolant temperature sensor, circuit open or circuit short
41 Left intake air temperature sensor, circuit open or circuit short
42 Voltage at mass air sensor too high/low
43 Tn-signal (rpm signal ) at left LH-SFI control module faulty
44 Oxygen sensor heater of left oxygen sensor, circuit open or circuit short
45 Camshaft position sensor signal of left ignition control module faulty
46 Intake manifold pressure at (in left ignition control module) faulty
47 Not used
48 Not used
49 Data exchange fault between left LH-SFI ignition control module
50 Left adjustable camshaft timing solenoid circuit open or circuit short
51 Left injector circuit open or circuit short or emission control system adaptation in left
LH-SFI control module at limit
52 Not used vehicle speed signal missing
53 Left purge switchover valve, circuit open or circuit short
54 Left camshaft position sensor signal faulty
55 Intake manifold pressure(in left ignition control module) with engine running too
low/high
56 Starter ring gear segments and/or left crankshaft position sensor faulty
57 Knock sensors or left ignition control module faulty
58 Not used
59 Left engine coolant temperature sensor deviation between circuit 1, and sensor
circuit 2.
60 Left engine coolant temperature sensor (engine coolant temperature change monitor)
