OK, i have a 93 lude, and i just swaped my blown h22a1 for the h22a, at first it was pulling like a champ, but recently it has been a little sluggish getting to vtec, and when it does hit vtec it pulls real hard at first, then crappy at about 6300rpms, i just changed the sparkplugs and synthetic oil....any ideas?

 

Clean the vtec solenoid? Make sure it has enough oil, check the coolant level, change the cap and rotor. Search? This has probably been covered a lot.
