Hi everyone I have a 1994 wrangler with 4.0, she never really gave me trouble at all until now. When you give her gas, it sputers and almost stalls, i ran sea foam thru it and it blew smoke so its def. not fuel. I got an error code 36 on the check engine light, wastegate cir. open , I know there are wastegate solenoids on turbo, what the heck is it. Air switch? and where is that little honey?
