LM7 motor in a L10

Off Topic

My son has put in a lm7 engine in a l10a, has some fuel injectors from a lq4, so a little bigger.
The car goes well when it is cold, but when he then restarts it and goes home it goes bad.
Have any tips?.

Sorry, the Chevrolet S10 should be.

Oh well. I hope somebody is doing that swap, somewhere… :smile:

I’d guess something to do with cold start enrichment. But I know almost nothing on those motors/ECU’s.
