hold the throttle open a bit while trying to start it with the line off.

Yeah it's probably not going to want to start really easily with the brake booster line off. Make sure you don't fry your starter trying to get it started.

just have the right tools available... and if you dont have small arms/hands, get someone over there who does to help you out.

i did spark plugs and wires and i didn't think it was quite as bad as everyone says... i mean it wasn't the easiest, nor the funniest spark plug change... but just take your time...

if you want extra clearance i think people take off there coil packs, but i didn't bother with that.

o and yea prepare to have your arms scratched up pretty good... there's some nice sharp *** pieces of plastic or whatever under there near the back plugs...

helps.

On the Seafoam, I had the same problem, engine would die as soon as I unhooked the booster line. I used a pair of vice grips to pinch the line closed, then backed them off to allow just a little opening in the line and fed the seafoam in that way. I used two little pieces of wood to pad the jaws of the vise grips so they would not damage the booster line.

ok so i did it and it worked.. i think. before the car cut off it was smoking pretty good, but after i started it again there was like nothing and it didn't spit out that much. was it really that clean? i just found it odd that it smoked a lot while still running, but not after it soaked the heads.

you can use the PCV line too.

whenever i did seafoam, when i disconnected the booster line the car sounded cammed. so maybe you have a leak somewhere else and the MAP will kill the car cause of the dramatic loss of manifold pressure.
