i would say your computer is bad.my computer went bad before but the car wouldnt run at all and i couldnt get it to read a engine code.i would try to put a new computer in it.i think i paid $115 for a new one.

if youre going to use those 30lb inj. which you dont neeed. to should get an adjustable fpr. so you can tone it down a little.

A floating valve is when the valve stays open, not long but it stays open, if this where the case though i think you would have some internal damage since the piiston would hit the valce when it comes back up, then the car would run crappy throughout acceleration
