Welcome to AF, engine lite blinking is usually a misfire issue, get it scanned and post back the codes.

also i wanna add that everytime it hits 30mph it feels like it pulls from the back once then the check engine light starts blinking and also when i turn on the A/C it struggles even more

This is over your head if you cannot scan the truck, get it to someone who can correct the scanner comm. issue.
