Hello all! this is my first post so be patient with me, and my first civic i got two weeks ago. gotta say i love it, but i got ripped off big so heres the deal. Found out my 98 civic 4dr ex has a swapped motor, D16Y5. and apparently the EGR is unplugged because theres no plug for it. When i bought it two weeks ago the CEL went on on my home from the dealership, code reading P0171 & P0170. P0170 went away after getting a new gasket and vacuum fixed. still getting the code P0171, and kind of worried about the unplugged EGR valve. But i love my MaSayVic, and hate seeing these problems, wanting to mod it and all, but dont know how severe these problems are. any inputs will help thank all ya honda fans!!
