lexy

Hey guys just picked up this 88 lx. Car drove great. Its got a mild cam, 70 mm tb exhaust (full) not sure what else. I put premium in her. next day I decided to put mid grade 6 gallons only. Tank was full. Now the car idles at 2 k rpm all the time. Once it idled at 600 rpm. Also feel a loss of power. Its not running smooth. I just cleaned aic, tb, maf, and new air filter. What could cause my problem. I wonder if putting that gas really could screw everything up that bad. Please help! I have no idea what other mods on the car. It was running great, then a while after 6 gallons of mid grade she started to act up.
