Car Misfires When Heats Up

[lucis]

My car heats up around 10mins of driving and the starts to misfire a lot

I checked the dizzy cap when it starts and misses 2nd and 5th no spark out of here, it's a brand new cap and rotor and the dizzy isn't that old

I just need this and my cars perfect

Yeah GTS r31 rb30

[mad082]

try new leads

or ignition coil. . check the electrical plug that goes into the dissy as the rubber breaks down and allows moisture(corrosion) to mess things up

[lucis]

I have new high performance leads and a new ignition coil
