ok update. Threw a CEL and check engine light came on after 118miles of driving.

Multiple misfires, so its definitely the spark/ignition wires. So im installing the new ignition wires tonight.

But also threw a P1174 code. Can this be due to dirty MAF? or could it be a bad SHUT OFF valve? seems 02 censors arent the problem with this P1174 code. (from reading other forums and people trying to address P1174, seems like new 02 sensors did not fix)

any thoughts?

thanks!
