Having problems with your 2005 Chevrolet Impala ?
I replaced the coil blocks, wires, and plugs on my 2005 chevy impala 3.4. I am still getting random misfireing, what else can it be?
Could be a fuel problem or a fuel injector. these engines are also bad to leak water at the intake manifold gaskets, if coolant leaks internally it would kill the spark and cause a misfire. if its not low on coolant though i'd keep checking fuel and fire
