Engine surging after it warms up...undriveable

[salvi]

Good morning,

I'm helping a friend with his car.  The car was sitting for about 7 months due to a broken transmission.

I replaced the transmission and got the car running again. 

The car starts fine, but after it warms up, the engine starts surging up/down and it's undriveable.  Once the car cools down and we try again, the same process happens.

I also noticed that when placing the key to the ON position, the fans will run continuously. 

The car is a Subaru 98 2.5rs with a JDM EJ20 something swap from the older pre-200 STI.

Any help would be greatly appreciated.

 

Thank you.

I create a log and sent it to TAC as well.  Attached is the log. If anyone has any insight, please post.

Thank you

You log shows it has massive trigger errors once it gets warm.  I suspect this probably means the cam timing is out but it maybe something wiring related.  Can you warm the engine up until it starts surging then do a trigger scope (while still idling).  Here is a quick vid showing how to do the triggerscope:     https://1drv.ms/v/s!AiYbYlZQuRHPmieMTkwQDCXEb2LY

That's what TAC said as well.  Attached is the trigger scope.  Just in case I replace the cam sensor with a known good one, issue is still there.

I would think that if it was a cam/crank sensor or wiring that it would do it right away?  Why is it that it only does it once its warmed up?

I also noticed that the fans are constantly running. Not sure if they have been rigged to do so.

 

Thank you.

That is only half of the triggerscope.  Please "save as log" as per the videos shows.
