Heater hose busted yesterday and replaced hose and truck now idles rough and will barely pull out its tracks and misfiring. Pulled coil out and with air compressor blew out the plug holes and it appeared to be coolant. After this truck doesn't run any better just skips and misfires. Any ideas???

 

The coolant probably damaged one or more coils.

 

Is there anyway of testing the coils beings the engine light doesn't come on?

 

Not really, not without a high end scanner - or by substitution.

 

replace the cops as needed....imo

 

try removing the COPs and removing the water from the plug holes, but it's probably too late
