Hi guys, Just wanted some thoughts on what happened today. I was driving and gave it a boot, I heard what sounded like something pop with air. After this noise I pulled over and the car was idling rough. Turned it off then back on and all good, gave it another boot to check and it seems to have not lost any power. Thought when I do boot it now I can hear like a metal rattling. Its a Ba turbo with a few mods, I put the elm on it and its only got the fault code ive had for ages which is (system too rich) any thoughts?
