Like the title says got the motor installed and drove for bout 300 miles or so back and forth to work etc... Coming home leaving a stop sign the engine backfired twice then picked back up. Car went bout 1/4 mile or so started skipping and died. Has yet to fire again. So here is whats been done/tested. coil has been swapped with working coil and coil has power to it. dizzy was just swapped today with no luck. control module on the pass. fender has been tested in the cobra works fine. cap and button have been replaced with new ones and have also checked the grounds. checked fuses in engine bay and has fuel pressure. open for ideas now......

Have you checked the pickup in the distributor? Is the cap and rotor good?

take the one out of the cobra. All it takes is a 10 mm socket (and your dad not around since it is his car

)
