In this video we show you how to replace an idle air control solenoid and clean the throttle body on a 1996 Saturn. This car was having a excessively high idle. It would stay at 1500 RPM even though your foot was not on the gas pedal. This was caused by carbon build up around and behind the throttle body as well as a defective idle air control solenoid.

How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.

Step-by-Step DIY Engine new head & gasket installation
Installing the head onto a DOHC engine block. New felpro head gasket
installed. Saturn S-Series. I chose to go with a professionally rebuilt
head due to burned and chipped valves. The reason for tearing the engine
down was compression issues. New head bolts should always be used.

I took care to make sure both the block and the head were at TDC Top Dead
Center prior to installtion to avoid any mechanical damage.
Most of my DIY parts and supplies for my Saturn project came from Autozone
and Advance Auto Parts.
I used a Felpro headgasket and put it on clean without any additives as per
My PCI timing kit came form ebay and included camshaft sprocket gears,
crank gear, chain, guides, and tensioners. I had to re-use the crankshaft
The rebuild head came from a reputable ebay seller and I am very pleased
with the quality.
