On a test drive today after repairing new injector with bad factory crimp, the short hose from thermostat housing line to manifold blew going 80 mph. Instant steam everywhere. I hobbled off the exit and parked ASAP. The temp gauge pegged. The driver side of the engine bay was pretty soaked. After I repaired the hose and got some water in it, it started and got me home but it ran rough all the way. Do you think its running rough because some things are wet or is it possible I did some more serious damage?

clean the throttle valve switch then dry it.

Also check temp sensor connections.

Check for water in the distributor. It will condense on the cap and cause problems.

Thanks.
