Intake Manifold Question

I have a 90 bronco with a 5.8l engine. I have notices a lot of carbon build up inside the upper intake manifold. I want to know if it is worth it to clean the intake manifold or just leave it. The car does run a little sluggish. If I should clean it, how should I do it.

Rarely hurts to clean something if you have it apart

I'd use carb cleaner... As long a there are no sensors or anything. A lot of sensors can be damaged by certain cleaners

Re: Rarely hurts to clean something if you have it apart

That stuff is usually tougher than it looks. I guess if you really want to go after it, needs to be done off the truck, after pulling off throttle body. I think the final clean-out will be critical. Don't want a sharp piece of carbon loose where it can end up in the cylinder scraping along a wall. Most upper intakes I've seen have looked pretty nasty, my natural inclination was to clean it out, but since i wasn't going to put many hours into it, just carefully cleaned up the edge by the gasket surface, and made sure the bits came out. I wonder if a wire brush attachment on a moto=tool or something with a flex shaft might be needed. And maybe a cleaner dip-tank! Unless something is plugged, i don't think it will make a whole lot of difference. If you were racing, it would be worth it for high RPM smooth flow. 302's look worse, as they have an exhaust passage for EGR flow. Looks like crystal city on high-mileage engines!
