Engine idles rough when I reverse???

[Sevenpelicans]

ALright I got two more things going down with my 93 XLT.

First, just recently my explorer has started to idle really rough when I start it up and then proceed to back up. I believe this is just the fact that the rpm's are going down when I click into reverse but, why?? I am thinking it could be the gas I filled up with the yesterday? That's about when it started??
What else should I check out and how should I fix it/

Second, My radius arm bushings have to go!! They are squeeking all the time and are so extremely annoying. Where do I get them and how easy is it to change them out? Do I have to get the car aligned afterwords? It looks like I have to take out the springs? How do I do that?

I would appreciate any advice thanks.

Bad gas is possible. Can try putting dry-gas in and see if that helps. Also, check your vacuum lines for leaks/popped lines or caps on the "octopus".

Go to the Singleton (Explorer Maintenance) site link in the Useful Threads forum. I'm pretty sure the R&R of the radius arm bushings is one of the helpful topics on that site.
