I own the vehicle listed above v6. I saw that you had the same problem as I did, and I received spark on the coil but not at the cap, even though the cap and the ignition rotor are new. What was the fix at the end?

Hello,

It sounds like you might have a faulty coil, coil is arcing to distributor housing when under load.

See video below.

You can test the coil resistance using a voltmeter. Please see specifications in image 1 below.
