Rebuilding my tbi? Is it hard?

[imiceman44]

I’m a total noob rock working on cars I’m learning as I go. How would I check for vacuum leaks? and if I find them is it as simple as a new hose? Thanks for any info!

To find a vacuum leak spray something flammable around the suspect area, when you spray an area with a leak the idle will go up.
It could be a cracked hose, loose hose, loose throttle body or even a missing or cracked gasket at the base of the throttle body.

Alright! So I sprayed a little strarter fluid around the vacuum hoses and the idle went up for sure. So I just need to replace those vacuum hoses?

Start with those... then check the rest.
