E320 diag codes

1995 E320 hesitates and runs rough. It has 180k. I changed the engine wiring harness about 3 years ago. I just put a new MAF sensor. My diag codes are.
code 10

Pin 8 4,13

Pin 14 2,5,11

I am going to put new non resister plug and coil to plug connectors in tomorrow. I dont think thats the problem. Its also coughs through the air box. I can here on acceleration. Please help.

Dave

Code 10 in the DM is relating to the mass air flow sensor
Codes 4 & 13 in the fuel ECU are also about the mass air flow sensor.

code 5 in the EA is related to the brake lamp switch & most "likely" has caused the other 2 codes

You may have some spurious codes. Try clearing the codes and reread them in a few days. See which codes reappear.

Try a search for the codes. They've been posted dozens of times.

Also try searching the posts made by Arthur Dalton.

MAF was Meyle german replacement. I changed the plugs and plug connectors and what a big difference. But still a small hesatation about 2100 rpm on accelaration. I guess I had more than one problem. Just wondering maybe I should check the fuel pressure?. First ill wait and see what codes come back.

B/C the plugs and connectors made a big difference, I would now reset the memory on pin 8 to get back to mean . Then run it and look for further codes.

Not to hijack, but what is the proper NGK plug for the M104?
Autozoo sold me BKR5E (resistor), is the correct one BK5E?
