My car is a 1992 with 59K miles, in the paperwork I have, which goes back to around 20K miles no injectors have been replaced, so that was my first suspect or the O2 sensor. The car is stock. Tom this weekend is not good either but next Saturday is, I'll check out the map sensor hose now I know what I'm looking for, the pictures are great guys, many thx.
What does a set of injectors cost? And what is involved in the install? If the coil has gone out would it still run rough like Im missing a cylinder or two and then somestimes it would run OK?

Thx Richard, thx for the great info everyone.
