It starts chugging/missing at about 45 mph. How can I determine what is causing it?
Run the fault codes. check the serviceability of the cat converter as it may be broken inside and blocking the exhaust

CHECK YOUR INTAKE AND THROTTLE BODY AND MAKE SURE IT IS TIGHT ALSO CHECK AND SEE IF INJECTOR ORINGS ARE SEALING AT INTAKE

Replace steering stabilizer and rotate tires every three thousand miles. Rotation is actually the most important. Took me two sets of tires, before they were worn out, to realize the problem.

My Death Wobble started immediately after I installed a set of Coil Spring Spacers (to lift 1.75 inches). Turned out, the DW was because while changing the height, I also lowered the CASTER angle in the front end. So, to fix it, I could have purchased a set of eccentric bolts for $50+. Instead I went out and purchased a piece of 1.5 inch flat bar for $10 from OSH. I cut out 4 1.5 inch squares. Then i drilled 7/16 inch holes centerline, but close to one side (in exactly the same place) on all for squares. I then removed the lower control arm bolts, nuts and washers. I installed these square offset washers I made so the front axle would be pushed forward (to increase the Caster angle). The toe setting changed a bit, so I reset them to about 1/8 inch toe in. After driving my Jeep, I noticed there is no more DW. The steering wheel was off center, but after 3 attempts, I have that perfectly centered. I have every intension of having the alignment checked, but not till after I find the new tires I want. If anyone is interested, I can draw out and photograph the cure and send it to you.

you can clean the old pump out with air hose and carb spray it take apart rember all the brown wires label them. The gasket gets old breaks down and clogs the pump cause it to do all the thing to run some time not run hit hill not run.

Not a tune up problem,
You need to have all U-joints checked out,They will give you the vibrations only while acceleration
