i'm in the process of rebuilding my d16z6 for my 94 civic. b4 it crapped out on me...i remember my vtec not kicking in like it was suppose to
first - acts like it's suppose to
seconds - feels like it's jumping in an out
third - doesn't even seem like it's even there
(i don't even try in 4th or 5th)

would this be b/c my vtec solinoid is not working properly?...or is there something else that could be wrong?....and also if it is my solinoid...will my car be able to run with a bad solinoid as long as i don't engage vtec (since after the rebuild i can't push it past 3k rpms for 2k miles)???
