my jeep runs great when cold but when up to operating temp it runs like crap, i checked the fuel pressure its good, no vaccum leaks, i can hook it up on a OTC Genysis it will show a ingnition coil #1 and #2 but i cleared it didn't come back on . I can watch it with the genysis when idling or driving no misfires on any cylinders. Could it be the ingnition coil bar?
It could be that it is suffering from heat soak which is common for a failing electrical component. Once it gets to a certain temp it doesn't work correctly but functions fine when cool.
