Rough Shifting after intake manifold gasket replacement
Hey there guys/gals,
I replaced my intake manifold gaskets two weeks ago. Right after I drove out of the garage, I started having a rough shift from 1-2 and 2-3. The problem wasn't happening before I changed out the gaskets. It happens every time I go 1-2 and 2-3.
I've checked all the hoses to make sure everything is back in place. I ran a diagnostic before changing out the gaskets, and it threw some codes saying to replace the EGR pressure sensor, downstream o2 sensor and fuel filter.
Any advice as to why i would be having this shifting problem all of a sudden? Think that if i replace all of the other codes that were thrown and the spark plugs it might solve the issue? I reckon i'm just trying to get a piece of mind that it's not a tranny problem. I don't see how it would being that it only started after replacing the intake manifold gaskets.
It's on a 2002 4.0 sohc 4x4 ranger.
Thanks so much for your help!
