Question
Just recently whenever the blazer is idle like when you start it or have to stop at a light it makes a sputtering sound and shakes really bad and acts like it is about to cut off. I haven't drove it for 2 days and when I started it up today it is much worse than before and the engine light is coming on. The blazer was bought from a friend over a year ago and all we've been doing to it where routine oil changes. The a/c doesn't work and when I got into it the other day when I first noticed the problem my boyfriend had drove it before and had the a/c turned on full blast. What could be the problem?

Thanks,
Misty

Answer
Hello Misty,
It could easily be a vacuum leak, and it could be related to the a/c controls.
I assume you turned the a/c controls off to see if it went away?

Plugs and wires could also cause it, as well as a sticking valve, or fuel problems.
