Truck runs like crap
I have a 95 ram 1500 4x4 5.2. I bought it off a friend. He cut the cat out of the truck when he did the exhaust. Put the 02 sensor back in and everything. Well it runs like crap lately. It almost dies at idle and spits and sputters, makes a weird hissing noise so i replaced the IAC valve. Didnt fix it. Also going down the road itll bog and hold itself there till i bought have to floor it to get it to catch itself and go. Any ideas? Im slowly giving up on this truck. Thanks

Hissing? Under the hood or elsewhere? If under the hood, spray carb cleaner at all the vacuum lines around the intake manifold-replace as necessary...if that's the problem it'll likely fix most of the rough idle.

Im not to familiar with the vacuum lines. It only hisses when it bogs down at idles and almost stalls out. Other than that the hissing is non existent. And I did not clean out the port I never thought of it. Would the catless pipe be a problem to? Just trying to eliminate possibilities here. Sorry for being a pain.

Dang. I just posted that and more...or tried to post....must have clicked the wrong button....
+1 on HeyYou's info. Also, while you have the TB off, take a small mirror and flashlight and look down the throttle body into the intake. Pay particular attention to the rear on the pass side. See if there is oil pooling up there. If so, your plenum is blown and this may be s=the source of hissing and bogging.

Check the plenum while you have the TB off to clean IAC port. Can't really see in there very well with TB in place.
