880joe Posted September 5, 2020 Share Posted September 5, 2020 Ijust put new remack engine in my truck when I ordered it I used vin# off truck I have with a 427 so it would have different cam key I took out 355/380 now I'm getting 3-2 code when you mash the throttle about the time it starts making power it cuts out and throws code let off fuel malfunction light goes away runs good as long as you're not really putting it under a load. Am I getting this code because ecm is trying to read old cam setting? I replaced cam sensor and it makes no difference Quote Link to comment Share on other sites More sharing options...

Mark T Posted September 6, 2020 Share Posted September 6, 2020 3-2 can come from vibration somewhere ( even driveline ) how's the wiring harness ? Quote Link to comment Share on other sites More sharing options...
880joe Posted September 6, 2020 Author Share Posted September 6, 2020 New engine wiring harness but the sensor shim may be the problem because I changed ecm off another truck and still had problem. How do I check to see if sensor is shimed correctly? Quote Link to comment Share on other sites More sharing options...
fjh Posted September 6, 2020 Share Posted September 6, 2020 Micrometer or calliper should work don’t know the spec 12 thou ? Quote Link to comment Share on other sites More sharing options...
Mark T Posted September 6, 2020 Share Posted September 6, 2020 I had a truck with the same problem. Guy deleted the entire file and downloaded the same file back into it. There was something about not just clearing that code. ??? seemed to work when he did it. Quote Link to comment Share on other sites More sharing options...
