Hesitant To Start

[dualscoopinchevy]

Hey guys

I've got a 98 5.7L Sierra that I just put an Accel Supertune Ignition kit w/coil in the other day. Worked out real nice, notice increase in start ease, higher rpm accel...etc. Well here is my problem. Just a little bit ago I tried to crack up my glasspacks. Ran my truck around town for a while, came home, parked my truck on a slight incline, killed the motor, stuck a hose in each one for a second. Didnt really notice a difference in sound. PROBLEM IS now my truck is hesitant to crank and when it does the idle rpms have dropped. Definitely a difference from how it has acted since the ignition upgrade. Did I possibly get water too far up the tailpipe? o2 sensor wet? cats wet? you think it will dry out? I'm nervous as all get out right now. Any help is greatly appreciated! THANKS!

Um....the hose was not a good idea. Yeah, good chance you get water in there.

Now that's just a really weird thing to do.

Man - never heard such a thing - "crack up you glasspacks"??????? So the water in a hot exhaust was suppose to do this I assume.....

 

Not sure how much water entered but water could be causing excess back pressure?

 

Also if moisture gets in a O2 sensor they go haywire. Prob remove and clean (see other posts how to do this) or replace if not sure.

 

Good luck - definately don;t recommend the water tick again.
