I love my Bravada but it has been showing its age (like many of us). Intermittant miss at low-load cruise speed. A/C is intermittant. Both problems occur after warming up.

 

low load miss AFTER warming up sounds like rings to me, when the oil in
that cylinder that's missing is warm it will no longer have
compression. However, it could also be something as simple as a tune up
that you may need.

 

lovin my 91, got 230,000 an still runnin strong, but definately has some issues. a/c? whats that?
lol
