car misfires/ stutters when horn pressed Wtf?
Hey all,
Civic EG9 and EG9.with same faults. Both seem to boost cut but aren't actually hitting boost cut. Feels like that and they lose throttle completely until you key off/on and both stutter slightly when horn is pressed on off. Never seen anything like it, both customers cars. Earths and obvious things seem fine, one is on hondata s300, one on crome pro. Both b18's, checked wiring for obvious , wired in 12v injector feed, fuel pump in with relay. At a loss as to what else could cause this.

I had exactly the same problem with my EG9. Weird thing was it randomly stopped doing it. Never got to the cause but i suspect it was something to do with my aftermarket horn and some grounding issues.
You have OEM horn?
