after you drive for a while and car warms up good it starts to like backfire threw the intake and wont take gas and runs bad till you pull over and let it set then after a while it does it again.Plus i checked the coils 1 by 1 and its like every other cylinder fires harder then the other at the coil packs.Iv replaced all coils ,ignition module,MAP sensor,MAF sensor and same thing
Check for a stretched timing chain.
