Re: 98\' SUB stumbling at mid-RPM\'s
Not trying to 'steal' your post but, I too have the same problem, except that mine's between 800-1500 RPM. I have virtually no excelleration, and dies on me inconsitenly while driving. I've replaced the cap, rotor, plugs, O2 sensor, EGR valve and have re-timed it. Also my Computer spits out codes for lean exhaust, low fuel pump relay voltage, and the EGR valve. Should I be checking the same things as Cosmo? Thanks.
