My 496 Mag runs fine first but when I push it a lite in 50 miles and slow down it runs verty bad.
I tried to lift cables from sparkplugs and it miss on two cylinder. The when I turn it of for 5-10 minutes it runs fine again for a while, then same thing hapens again.
I have new sparkplugs and fuelfilter.
What could be wrong?
