Clunking noise at right passenger's side

When it's hot out my car won't start, any ideas?
A couple of things come to mind. I would first ask these questions: Is this a no crank or a no start? I will address both scenarios below. A no crank is when the motor doesn't turn when you...
Randomly, car stutters, idles, stalls, and won't start

Hooked the car to a computer a tune up and the o2 sensor came up.
Based on the information you gave, these may be different issues. The loss of power and jerking are indicators that you probably have a misfire. I would suggest replacing your distributor cap, distributor rotor, spark plug wires and spark plugs...

Wow, manual transmission Volvo's are really hard to find. It sounds like you have a slipping clutch. This is pretty normal behavior for a worn out clutch, and with 170,000 miles, it's due for it. I would suggest having the...
Whining noise coming from back left of car when not moving as well as moving
