if anyone could help..please do lol

"service engine soon" light is on..took it to autozone. Says Random misfiring. replaced the plugs, wires, dis. cap & rotor. Still no luck.Replaced the Coil too. The coil seams to be making a rapid ticking noise. Motor seams to build up when idling and is rough when taking off.
Have cleaned EGR valve and put a new gasket on it.
Thanks

there might be a fault in you fuel system or electrical. Check your hoses to you might have a vacum leak. If that doesn't fix it check the cylinder compression.
