Howdy folks -
I picked up a 1999 Suburban K2500 last week and have been going through it getting her ready to tow my travel trailer. A few days after I got it it started stumbling bad at speed. This weekend I changed the plugs, wires, cap and rotor (cap was a huge PITA to swap out). It is running MUCH better (#7 plug wire was burned through completely at the boot), but I've still got a stutter all through the rpm range. It's almost not noticeable when driving around (blends in to the road noise and feel). When sitting and revving though, it's vibrating all through the rpms.
What should I check next, and how can I help isolate the issue? I'm guessing it's ignition related, but not 100% sure.
Thanks!
