1994 Sport rough idle

[Strife]

Wanted to see if I could get some help with my 94 explorer sport 4.0 OHV. I just changed the lower and upper intake manifold gaskets and spark plug wires, ever since then it seems to backfire, run rich and has a strange kind of raspy noise coming somewhere from the exhaust system. I checked for vacuum leaks on all the tubes and around the air intake using starter fluid and no go there were no leaks. Also pulled some codes as well 114, 332, 335, 452, 542, 543, and 565. Any suggestions or info would be great.

Go over your previous work as it appears you have a lot of things disconnected.

452 (M) Vehicle Speed Sensor (VSS) problem. This is in the end of the transmission where the speedometer cable would have lived.

The 500 series codes are fuel pump related.
