My 95 3.8L has started acting up with very rough idle, it fluctuates between +/- 200 rpm every 5 secs approx. My throttle cable is a little loose, dou u think thats the cause?........

More likely a dirty MAF or your Idle Air Control module needs to be replaced.

Have you tried changing the O2 sensors. Whenever I start getting bad idyling, it's been the O2 sensors each time. How many miles do you have on the sensors?

I've never had a set of o2 sensors go bad that affected idle and I've owned 4 fords with a combined 700000 miles.

Only once have a set gone bad, and all that happened was the CEL came on. It didn't affect idle at all.
