Re: valvetrain+injectors

<x-flowed>Your car has hydraulic lifters, so there is no adjustment.  Usually, they 
make noise in the morning when the oil is not warmed up but should quiet 
down within a couple of minutes (sometimes 30 seconds).  If your valves are 
continuing to tick long after your car is warmed up, your lifters need to be 
replaced.  What oil weight are you using and what is your climate?  These 
things will factor into how much noise your valves will make.  Some of us in 
the south can run 20W-50 all year, but it's too thick in the winter for the 
Northerners.

A lot of things could cause idle and hesitation problems when the car is 
cold.  There is a warm air feed to the airbox.  Is this working?  I think 
your car would have CIS-E.  The idle stabilizer valve might be stuck or not 
working.  If you turn on the A/C does the idle increase?  If it does, then 
the valve is working.  Dirty injectors could also be a culprit.  I don't 
think it sounds like you have a vacuum leak since that should show up at all 
times, not just when the car is warming up.  I usually notice a little 
slowness in my car when it's cold, but it goes away in about 500 feet of 
driving.  How long has it been since your car has been tuned?  The mixture 
could need adjusting.
