I have a 2000 Rodeo 3.2 auto with 140k miles.

I started having problems recently where when I give it a lot of gas and take off fast, it will take off fast until I let off the gas, and then it runs like crap for a couple of minutes (acts like it wants to stall), and then it will start running normal.

I did a tune up, changed the spark plugs, air filter, and crap like that, but it still does it.

Any thoughts?

I just put it in the market for sale, and I need to fix it ASAP

May want to consider a new fuel filter as well. Had a similar issue years ago that was remedied after changing the long forgotten fuel filter. :wink:

Could also be the intake manifold gasket.

The throttle body maybe carbon'ed up and needs to be sprayed out.

EGR and the EGR tube and PCV may need to be cleaned out.

I know that has to be bad because the truck always runs rough when I first start it up in the morning, then runs great when it warms up. But it has been like that for at least a year.

I have never had a problem with giving it a lot of gas, and it wanting to stall afterward.

I'm going to replace that today and see what happens.

throttle body is ok

I will try and clean out the EGR and PCV
