96 altima intake gasket

New intake gasket installed, skipping now gone but now the car idles too low. Is it Ok to adjust it with the throttle cable adjusting nuts? I guess the vacuum leak raised the idle? The gaskets I changed out were not broken, I was afraid all of the work was going to be in vain. Thanks for the help!:grinno:

update! The skip is not gone. It looks like I changed the intake gasket for practice. I've got good fire to the plug, and a new plug installed. I can unplug the injector on #4 cylinder and it does make a differance in the running of the motor but not nearly as much as the other 3 holes when they are unplugged. One at a time of course. I guess I'll replace the injector or at least swap it around as suggested before, to see what happens. Thanks for any more advise.:banghead:
