I have a 1991 Dodge Daytona which I just put a new motor in. I had it idling for a few seconds with the idle going up to 2500 rpms down to about 300 and back up then it dies. Well now it won't idle at all and I check fault codes, and theres 6.
Fault codes:
11 = No ignition reference signal during cranking OR timing belt skipped teeth or loss crankshaft position sensor.
12 = battery or computer recently disconnected.
15 = No speed/distance signal
24 = Throttle position sensor over 4.96V
25 = Automatic Idle Speed motor driver circuit shorted OR target idle not reached OR vaccuum leak found
41 = Alternator field control circuit open or shorted
55 = end of codes

Thanks
