Ok, my mods are all listed in my profile so check those.

It seems like every other couple times i fire my car up i will have a bit of a shakey idle and what appears to be a vaccum leak. (My boost guage will read like 15 vac) It will stumble and miss while warming up and then if i get into it a good deal through a few gears it will run fine.... Has me stumped because i did a leak check and cant find anything. From reading i havent found anything like this so i need some HELP!

Tomarrow i am going to replace my pcv valve and fuel filter. Any suggestions would be great!!

Thanks, Alex
 
My suggestion is to check all your spark plug wires. It could be hard to find, but one of them could be a little messed up causing it to work right sometimes and doing what its doing to you sometimes. I guarantee its not a leak although you might have one. I had this same problem about six months ago where when I would punch it the car would sometimes cut out and it ended up being a bad spark plug wire. You should still change the fuel filter, but next thing on your list should be wires and plugs.
 
Thanks, will do. I replaced the plugs and wires a few months ago, but since then much has changed on the car air/fuel wise so i probably should change the plugs. Thanks!
