Cylinders 1&4 problem

[crazyquik22023]

so cylinders 1&4 aren't firing in my car. I haven't figured out yet if it's the ignition coil, power transistor, or ecu. This problem started happening after i was racing boosting 21psi, and it happened right after i was going a high speed (155+) and happened right after i let off the gas. anybody think that one of these problems is more likely to be caused by this? Thanks

Well start with the basics. Check for fuel, then spark and work your way up from their. Most likely its probably a bad coil pack

ya neither cylinder 1 or 4 are getting spark. and ya i hope its probably the coil pack i ordered one yesterday i just keep thinking it's gonna be the power transistor though

My guess is the coil. They're two separte units on one bracket. And 4 & 1 are together. Also, don't talk about going 155mph on the street. It's horribly frowed upon here.
