I have a 1997 XR7 that recently started skipping and throwing codes. The codes showing on the scanner are
P0353 Ignition coil, primary and secondary;
P1443 Emissions Purge Valve Malfunction;
P0304 Cylinder 4 misfire;
P0307 Cylinder 7 misfire.
All of these codes came up as both pending and confirmed.
I have replaced both coil packs, all the plugs, and plug wires and found broken/ dry rotted vacuum hoses that were also replaced. Cleared the codes and scanned again as the skip is still there. The only code that comes back and it does it immediately, is the one for the ignition coil. So far 3 new coils have been in this position. There is 14.2 volts going to the input power wire for each coil pack.
I don't know what else to try as the code scanner won't point me in any more directions. I am open to suggestions and any help anyone can give.

Cylinders 4 and 7 are on the same coil within that coil pack. I'd check continuity on that trigger wire from the EEC to the coil.
