Alright, so two days ago my car ran fine and yesterday i jumped in it just like normal and at idle to around 2500 it runs alright but then it just ran like absolute crap. So i bought new plugs, distrib cap and rotor button, plug wires, full tank of premium with seafoam additive. checked the oil and its normal. i pulled the new plugs and its running very lean. can anyone help?

You're in limp mode. Check your MAF plug

its not cutting off at 2500 it will still rev till 6k it just doesnt like it

i also put a new fuel filter on, and around a week ago i installed a 10"JL do you think that might have caused a ground issue? just trying to put all the info out there
