I have a 2002, F-250, CC, 4x4, Lariat. I also have a GOLD Superchip in the PCM - came with the truck that way.
I ran an AE check recently and got the 1316 DTC.
Now my laptop with the AE on it is down.
So, where would I find the location of the Injector Drive Module?
From other threads, I gather that the HVC connectors under the valve covers can be responsible for the 1316 DTC. I plan to pull the covers this weekend.
This is an intermittent problem. When it happens I notice a slight roughness, the check engine light comes on, the roughness goes away and the light goes out.
This sometimes happens two or three times in a short time and it then may not happen for a day or more.
