Vaccum leak or distributor?
Hey guys I am not a member to this board but Im using Dave's name to post. My name is Gary and yesturday we put new "stock size" injectors in my buddies 87 TPI GTA. Since we had to take the entire upper intake off we replaced all of the upper gaskets. I used the injections from Dave's old TPI engine so we didn't have to disconnect the injectors from the fuel rails. The new gasket kit came with injector o-ring seals. I replaced the o-rings and installed the injectons and fuel rails. I made sure that everything fit nice and snug before I tightened them down. After that we connected all fuel lines and installed the upper intake with all plugs, vaccum lines, and new gaskets. During this project I noticed his coil and cap and cap was all pitted and white. We replaced the cap/rotor and coil. When we were done the car wouldn't idle. We were able to keep it running if we gave it gas. What do you guys think this could be? A vaccum leak maybe? All intake bolts were nice and tight and the gaskets were on correctly. It also doesn't require a brain surgeon to replace a cap and rotor so Im thinking that is not the problem either. Please help!

try keeping the car running and have some1 listen under the hood. did u hook up the vacuum lines from the charcoal canister that goes under the throttle body and snaps up to it? thats an easy 1 to mistake/forget.

It could be a vacuum leak, or one plug wire crossed(does it miss?), or the plugwires are out of rotation by one so base timing is slow.
You can spray carb cleaner around any gasket os hose connections and it will bog a little when it sucks a lot of cleaner in, so that will be a leak...
