Furd. Need I say more? 1993 Cougar, 3.8L EFI. Auto 3 speed, with 4th overdrive. Well, it runs, but has less balls than a Catholic choir boy. It's always been sluggish, but there's been something causing it. It's always stuttered erratically since I got it about a year ago, and the stutter has followed me through an engine swap (exact same type of engine, only difference was miles and condition). I thought it was a vacuum leak, but my mechanic friends threw that out the window. So I changed the air and fuel filter, but it made no difference (even though I could barely blow through the fuel filter). So can someone make a diagnosis for me? Cheaper the better! If you need more information, just ask, and I shall answer. *sigh*. Hope I can get a 4runner soon.
