I bought mine this month, and the seller (a garage actually, the sale part of a charity they work with), and the seller installed all new tune-up parts "to get rid of a rough idle". My first tank of gas ran SeaFoam with it, and it runs fine!

These v6's were never smooth like a purpose-built V6 (like a GM 3.8).

I LOVE this truck! Best $2200.00 I ever spent!
