The FDNY is giving City Councilwoman Liz Crowley a hose-down for publicly touting inaccurate ambulance-response times.

Crowley blasted the department and Fire Commissioner Daniel Nigro Tuesday for what she described as an “unacceptable” spike in emergency response times last month — citing an “appalling” response of 11 minutes and 7 seconds.

But that figure was wrong, according to FDNY figures, which clocked the responses at 9:38.

“We’ll give her the benefit of the doubt that, while she was wrong, this was an inadvertent mistake,” an FDNY spokeswoman said.
