weird idle now lazy no power need help

[grdsm]

Okay today I go to start my car and it starts like it always does, running at about 2000 rpms and reving up and down about 500 rpms. I fix the bosst leak that it had and go for a drive and it runs good then it starts to stall a little as I am drive about 3000 rpms. I have my mbc turned all the way down so I am not boosting. I notice that my fuel return line has no clamp on it and is leaking a little. I put a clamp on it, start it up and now it is at 500 rpm rough and very lazy doesn't want to pick up speed of even rpm up at stand still. I turn the idle screw on the trottle body and it only make a difference of about 100 rpms sound like a lawn mower. Anyone got any idea? please help.

Like a lawn mower? Check for exhaust leaks? Sounds like you have a nasty one.

You may have unplugged your number one injector by accident.
