my 94 ranger has a rough idle and has white smoke coming out of the tailpipe anybody got an idea what might be the problem?

 

Means you sucked a gasket my friend. time to pull the heads off.

 

seriously? i mean it's not like a lot of white smoke but you can kind of tell there is some and it smells like its burning rich

Which one?

 

I dont know if you sucked a gasket, but you definately are running richer than normal. I had similar issues with this on my 03. I pulled the intake manifold off and tested the injectors to see if one was possibly stuck open, all were fine and tested with the correct resistance. I then decided to change the fuel filter and since it had not been done in ages and it ran perfectly. I would also verify that you do not have any vacuum leaks as this could cause your engine to think its running lean and dump more fuel to compensate for the leak. I would investigate these things before throwing too much money into ripping the head off.
