Did they have probable cause and can I sue?

I was recently arrested out of my home county on Tuesday for fleeing. Prior to this arrest, I had a completely clean record. It was 4:30 am and I was heading home. I was leaving the bar, but I was not inebriated. A rough estimate of my BAC at the time is 0.017. I wasnt even given any dui tests or breathalyzer tests. I immediately pulled over upon noticing lights in my rear view mirror. The officers told me to drop my keys on the ground and handcuffed me. The arresting officer interrogated me as to why I was fleeing while others searched my vehicle. I was not given the option of refusing or giving consent to search my vehicle. They found a marijuana pipe, but no drugs. Also, I do not believe I was read my Miranda Rights but I could be mistaken. The arresting officer never once told me why I was pulled over in the first place. I had no traffic violations, wasnt speeding, swerving, nor did I run anything. I got arrested and got two felonies: one for fleeing and one for paraphernalia. The distance from the bar to my arrest location is 1.3 miles, but they couldnt have been following me from the bar since they wouldve given me dui tests. Will I be drug tested for court?
