[Luis83]

Please help my tahoe started to shake bad when i make a complete stop... I took of the intake cap that says vortex and noticed that it sucks to much air....this is getting annoying ,,,it may be a misfire???

What year and engine?
How many miles on it?
When was last tune up?
Does check engine light work and is it on?

Go to Autozone and have them scan for codes and post back what they are if any present.
