my 93 3.1L had been running a bit rough so I took it to my mechanic where it sat for quite awhile. He was leery of fixing what he thought was wrong because he said that [whatever it was] is easily broken when working on it. It was a sensor or something, I really can't remember.
It's just very sluggish to drive, lacks power, almost shakes.
It also has to be jumped in order to start. It has to sit, connected to another vehicle for a good 5 minutes, but will eventually start, but is very slow to start, you can hear it turning over several times before it finally starts. Does this sound like the starter is going out as well as a battery that needs replacing?
Thoughts on the running rough? Clogged cat. perhaps? Sorry I can't remember what my mechanic originally said, just that it has a tendency to break when working on it (could be because my car is so rusted out LOL)
