Bad misfire or not? Video included

[Marchev]

Hey guys, I have a problem with my 90 talon. I recently finished turbocharging it, and the car drove great for the first week or so. Then I started randomly getting a CEL and the car would "misfire" or stumble really bad. It seems like it's getting worse and worse because yesterday I barely drove it home. Seems like the more I drive it the worse it gets. After about a 20 min ride yesterday, got to a red light, car started stumbling and throwing the CEL then died 4 times within a minute. I couldn't keep it running even when revving it to 3k. Boost leak test was done and a few leaks were found. I'm thinking bad caps on the ecu possibly? My mechanic couldn't retrieve any codes for the CEL. Please watch the whole video and let me know what you think.

Thanks!

It sounds like the MPI relay is clicking. Check that first.
