Rough Running
My son's Camaro (98 3.8l V6 Manual gearbox) is running rough.
The engine has just had a top end rebuild including a new ECU. It had new coil packs less than 18 months ago and new plugs during rebuild.
Its now thrown an 0304 code showing misfire on cylinder 4. Before I replace the coil pack is there anything obvious to check? New plug leads maybe?
Thanks guys
