ok guys as some of you know, my car has been idling high and have a major vac leak. so i had take the upper intake off and fixed the vac lines under it, and checked the gaskets. now i have put it back together and add 24lb injectors with 24lb sample tube. the leak isnt as bad, but theres still a slight whistle that comes and goes. and my idle will stick at around 1500 and then go towards 900 and die everytime. i think when i hear the whistle the idle raises up itself, and when there is no whistle the idle goes to normal and dies. if i dont give it some throttle it will die out.

so if went from always idling around 1500 and never dying out, to idling high half the time and dying out the other half...im confused.

What could cause that?

sounds like you are running a bit rich at idle. What MAF are you running?

76mm 24lb sample tube. i cant figure it out, i know it was running lean due to the vac leak. but now the leak isnt so bad and its dyin out.

first you need to track down that leak. obviously it has something to do with your idle surge.

yah i just took it off like a week ago. the plate was gunked up and i cleaned it.

is your timing the same as it was. if you removed the distributor then recheck your timing. you def also need to find that leak. spray some carb cleaner or starting fluid to pinpoint it.

that could very well be where your vac leak is.did you change the gasket or put any rtv on it?

yah i changed the egr spacer to intake gasket, but not the t/b to egr spacer gasket. and the stuff the t/b plate was gunked up with was a dark brownish gooey substance?
