Can't get rid of the miss in the new-to-me OBD1 truck. Have multiple folks saying it'll take a camshaft to fix it. Specs: DGYS 4-Speed Auto 47RH Transmission DHAS Lock-Up Torque Converter DMDS 3.55 Rear Axle Ratio DRES Dana M70/267MM Rear Axle EWA 8.0L V10 MPI Engine It's got under 70,000 on the odometer, but it sat for several years and the TSB was not performed for the plug wires routing until last month (yep, we did that, and yep, it helped; but it didn't fix the miss completely). What would y'all recommend if I'm happy with the torque now and wouldn't mind getting a hair better fuel economy? Thanks!!!
