I recently replaced my intake gaskets (141k mi.) as they had blown out on the pass side front

After startup, it threw p0300,p0305 - the ignition stuff was new, so I decided to replace the injectors (can also cause misfire) since the fuel line wouldn't hold pressure for more than a minute after shutdown.

Amazon - $179 + $6 ship (with the $20 bracket) delphi spider/electronic injector ass'y. - bought it sunday, had it tues

(I'm a retired mech with tools, took about 1-1/2hr w/o hurrying)

Although it ran "OK" before, now it starts instantly, idles smoother and I hope gets better mpg (was 12ish city)


Will follow up later

luck,greg
