The first of a new series, Wrenchin’ on the ‘Rolla, where I work on my 2004 Corolla with 5 speed manual transmission, an ongoing project towards perfection. On today’s episode we replace the intake manifold gasket, as well as clean the throttle body and idle air control valve.

This tutorial covers the 2003-2008 (9th gen) North American Toyota Corolla, although for the 2005-2008 models the throttle body is slightly different, the intake manifold is the same for all years. It should cover the Toyota Matrix as well as Pontiac Vibe of the same generation as well, any model sharing the 1ZZ-FE engine (not the XRS/GT models with the 2ZZ-GE engine).
