Hello to my much loved Fiat Family! I seriously need advice on my Turbo Charger. If I hit 3500 rpm, I suddenly lose pressure in the engine and have significant power issues. The problem has come and gone over the years and the diagnostic equipment says I have no power boost. The turbo is right behind my radiator in the front of the car and it was suggested I check for a loose wire. Can someone tell me where the wire might be located? And if I find that it’s the turbo itself that needs replaced, how difficult would it be to do myself? Recommendation on best place to order the part from? Engine light is on and solid. Must do something as plates are expired, but in Ohio with e-check, it’s an automatic fail if the engine light is on.
