1988 460 engine issues
I have a 1988 ford f350, when I start it up it idles very rough and when you stop at a red light it acts like its going to die. When driving it normal it runs great but once using it for towing its seems like your pulling with a 6 cylinder not a big block 460. Not sure if I got a vacuum issue or the EFI. The truck only has 48,000 miles, 2wd single cab dually 5speed. Thanks for any help.

How old are the plugs, wires, cap & rotor?
Is the Check Engine Light on?
Regardless if it is or not, run the Key On Engine Off (KOEO) tests and Stored Code display. List the two digit codes by number and when they were displayed.
