Any advice on CEL + power loss?

Another CEL and weird Idle ...

--------------------------------------------------------------------------------

Hey all:

Total noob here ... bought a little project to work on with my sons. I had just finished swapping a diff and took her out for a drive and then the following happened:

What I do know:

Engine idles appropriately at startup and engine rpms do not fluctuate (listening only … Tach is not working).
No backfiring
Filled up with Premium Shell Gasoline (92 octane) – tank is full.

CEL comes on intermittently … on the way home it stayed lit then the symptoms began:

1. Loss of power – pedal to the floor, 4th gear, 50 mph and power loss occurred
2. Lugging with intermittent CEL – this happened multiple times (4 times) getting on freeway and before.
a. Car would be driving normally
b. Cel comes on solid
c. Engine begins to lose acceleration
d. Within 4-6 miles power loss – lugging
e. Pull over to side of road… shut car off
f. 5 or so min… start car
g. Cel off
h. Starts fine…idle ok
i. Repeats

Just starting my research and came across relays, but any other suggestions?

Thanks, Gerta.
