I had the AEM tuned on my all Trac a couple months ago and its been running fine. Drove it to work last week drove fine. After work it wouldn't start. Or it would start and not stay running. It sat for a day and I started it and it was running rich like 10:1 and like shit. Let it sit for a couple of days and started it up ran fine...for about 10 minutes then started running like shit again and died. I've checked wiring for the map sensor, wideband and everything seems in tact. I've checked intercooler piping and vacuum lines and everything is connected.
Any suggestions or thoughts? I'm at a loss.
