i hate this dreaded code P1138 i found out that its a Swirl control valve and thats its a Manufacture only part which costs about 500$ then another 400$ to install it. I found a full engine at the junk yard with only 30k mile for 350$. Does anybody think i should just purchase the full engine at the junk yard then just use that one piece. Any suggestions because im not about to pay 900 to 1000 bucks for a freaking swirl control valve. I dont even know what it Does. Any Suggestions???
