I'm having issues with my '85.
As far as I can tell, there's no ignitor problems or vacuum leaks, but I have high rpm,low speed and slow acceleration.
The high RPM only affects 1st through 3rd for the most part. If I don't put it in 4th by 40mph I'm between 4 and 5k rpms.

I need help diagnosing if it's the clutch going out, or if it's something else.

I don't have the money to take it to a mechanic and say check my car, so I need help.

Another main problem is that I have no tools at all to use since I'm in college.
