1996 Dodge Ram Hesitation

Hi:
Start with general things like checking for vacuum leaks. If no luck, make sure the catylatic converter isn't clogged. Also, make sure that the fuel pump is producing enough pressure. If everything checks out ok, I would recommend performing a compression test on the engine.

Let me know what you find.

Okay, But how would I check for clogged catalytic converter's?

What would be the best way to check pressure for the fuel pump?

You can liisten closely to the exhaust for a hissing, or ratteling sound. Also, see if there is a lot of pressure coming from the tail pipe. Last case, you can check back pressure with a gauge.

As far as the fuel pressure, you will need a fuel pressure gauge. Most nationally recognized parts stores will rent or lend them. It will hook to the fuel rail, and you check the pressure right from there.

Let me know what you find, or if you have other questions.

NOTE: If the converter is bolted on, you can temporarily remove it to see if that has an effect on the engine.

Okay, The exhaust does make a noise that sound's like a miss but it can only be heard thru the exhaust. The exhaust is aftermarket but also has damage in the piping.

I forgot to add that if in park, it will rev perfectly and only does it while it's going down the road is when it start's it's hesitation
