OK so after i had my car in the shop they fixed the Idle air control valve. idles fine now. only thing is when i boost and the bov goes off or i rev the engine the temp guage moves and stutters. its reading the temp fine(so i guess) but is that ok and normal. is that just a lose connection somewhere .(BTW i have a KOYO alum rad) should i look into it asap or not worry . i checked the fluid and the rad and over flow tank are both the same for the last week. any thought, comments?? thanks
