start up problem, not so much that it wont start up its after the car turns on after a day of sitting there, i turn on the car ans the idle goes up and down the engine spudders and when i step on the gas it sounds like its going to cut off, so when i turn it off and turn it back on 2 seconds later it runs fine rpms are perfect and revs up fine, its a b16a stock i fixed all check engine lights, so now im stumped..

Please help

thanks in Avdance

FLuctuating idle?
vacum leak ? clogged EGR (you should be able to push down a little on the top plate of the EGR solenoid. Like tuperware

hey maybe a leak down test ?

 

I'm having the same problem on my b16 let me know if you figure it out.
