ok well a little while ago i hooked up a vacume gauge to the engine, well when the engine is warm and at idle the needle is very rapidly bouncing from about 10 to 15, but when you give the engine a little gas to bring up the RPM's its stable.

also the engine runs REALLY ruff at idle, but fine at any other time through the RPM band.

i recently stripped most fo the emissions, i left on the things taht put air into the exhaust, but pluged them. can someone please give me some ideas on what i can do to fix my problem?

Thanks,
Shean

Signs of a bad air/vacume leak. Use a can of starter fluid and spray small shots around where you made changes. A change in idle will give you the location.

ya i figured vacume leak, but wasnt sure, i have been sprayin starting fluid, ive used up 2 full cans now trying to find it, and cant find anything. but when i do its on hoses that i never touched, maybe since the other junk is gone it magnified the others. looks like im replacing the rest of that junk.

Thanks,
Shean

oh, can i just run a hose from one vacume port to another rather then cappin it off, thats what i did on alot of stuff, or should i just cap them?

Just make sure the hoses you use dont have holes and they make a tight connection.

did the problem start after your emissions equipment removal? amazingly some of those parts are meant to be on your motor.:confused:

as for the vac. line question. that may or may not be ok. if you ran a venturi vacume source to a manifold vac. source that would definatly give you the problem you have. vac caps would have been a better choice.
I know I am not going with the popular belife that removing emissions equipment is "good".
nevermind the fact that winters are getting shorter and shorter each year. the president says that his own advisors are all wrong about that silly global warming issue so its ok.

another thread along the same lines as yours. might want to check egr too.

well it started after i spripped the emissions, but it also cured my studder problem around 2k when driving. so looks as if im going to be putting some caps on, and try to keep trackin it down.
