cutting out under wot
So I have a 2005 gsr and has hks 272, cams ported fp green, injen ic piping, godspeed intercooler and a few other mods. The car has ran great for me till I just recently changed the exhaust manifold to a megan header and the car ran good for a couple weeks and then all of the sudden I started getting horrible fuel mileage and drivability became horrible, my afr started going rich (11) while just normal driving and as soon as u go wot it would start cutting out and bucking and wouldnt accelerate at all but if u let out and hit wot again it would usually take off. So I started looking around and found the megan header was cracked so I put my factory ported manifold back on thinking that was my problem, but my problem was still there so I pulled sparkplugs and they were whitish but the ceramic insulater was a redish color and the part that the electrode arcs off of way a yellow color,so I put an old set of plugs in that I had laying in the garage, still same problem so next I went and ourchased a new front o2 sensor but the car still cuts out and bucks but now my spark plugs are black. Im am starting to get pretty frusterated with this car and any help would greatly be appriciated cause im lost. Lol

Not yet that was the plan yesterday until I drove it and it felt way better until today. But yesterday I had a vac line pop off and it wouldnt build more than 8psi but after.I fixed that it is now back to 28psi
