Okay so i got my VE tune in JWT, step down harness. I got the idle good earlier at 900rpms. Pulls hard everything is nice. I go inside my house and come back out to leave and the car is idling over 1.5k so i look at it everything seems good. I get to walgreens and i wne to touch the ecu cause its on the pasenger side and it made a clicking sound and the idle dropped and started to lobe. i shut it off and went in the store. when i came out i turned it on and the idle was fine. Touched the ecu and it did it again. Any ideas?
