Okay so about 2 weeks ago I noticed my rpms would drop intermittently and the engine would begin to bog down. I noticed this when I began to notice my a/c was not blowing cold air consistently through the vents when turned on. I had a mechanic ride along with me and he believed the compressor was about to sieze so I took it to a shop and they replaced it, did a vacuum/leak test, and recharged the system. I got the car back today and began to notice the issue again, this time taking note that my compressor would neither stay engaged or disengaged. It would be about 5 seconds on, 5 seconds off. I'm really getting annoyed with this and would like to hear any potential suggestions/fixes.
