Need help with choosing an ECM
I have a 1995 F150 4.9 4x4 M/T no air in head smog. I used to have the E4OD but did a manual swap. I got a rebuilt ECM but I think it's bad and its probably not the right one. I have a persistent codes 213, 311, and 225. Sometimes on the dynamic test 225 doesn't come up. The 213 code has been on the truck for at least 2 years. Spark plugs indicate that its running lean. I need to know the correct part number for a 1995 4.9 m/t ECM. I think theres 3 or 4 different 4.9 m/t computers

213 - Spout. Check your timing make sure it is not too far advanced. The spout plug is removed when setting the timing.
10 degrees is where it should be set at if I recall correctly.
311 - Thermactor Air System Fault part of the smog/emissions system. any vacuum leaks missing hoses?
Start by trying to resolve those.

I did check timing a couple months ago and got it right at 10° with SPOUT plug removed. I noticed with SPOUT plugged in, computer advances timing, and unplugged, timing was steady.

I do. Unfortunately it's for an automatic transmission, E4OD. Its SUB2. I swapped to a manual transmission.

the computer will advance the timing with the SPOUT in, thats what it is supposed to do.
I'd clear the codes and then check it again. was the engine at operating temp when you read codes? do a KOEO,CM,KOER test

KOEO: 111 System pass
KOER: 311, 213 225(if I floor it longer no 225 code)
If the ECM is advancing timing with SPOUT plugged in, yet still thinks the SPOUT signal is open, how can that be?

You didn’t need to replace the computer. It would have run fine but would have had the obvious codes for the missing auto trans.
What computer did they give you?

Well it was dying when I pressed the clutch to downshift due to different idle strategy. Loosing power brakes going downhill isnt good. I think its ANT1 ECM.

I actually had to have my truck towed today because it wouldn't start. The ICM was bad. Plugged my backup in and it started right up. I checked codes after the new ICM. Connections are clean with almost no resistance through the connector.

I have done extensive testing in one of my older posts. 213, 311 help is the title. I just ordered a new PCM. I got some help from OBS Revolution on Facebook. I'll be at a complete loss as well if a new pcm doesn't fix it. I know if I find a solution, I'll update the threads.
