It doesn't sound like you got it tuned.

Sounds like a misfire. Pull the codes with a scan tool immediately. Do NOT reset the ECU.

Doesn't a blinking CEL usually mean uh oh? Did you take a look at your spark plugs yet?

Blinking CEL means it's misfiring bad enough to damage the Catalytic convertor.

Did you pull the spark plug like Folex187 said.

Are you using stock plugs? They are too hot you could have nuked one .

Do you have a wideband gauge? or have you ever dyno'd it with a wideband to see what your A/F is?

just replaced the spark plugs and one of them were definitely bad but car still has blinking cel and idles hard the whole car still shaken

Make sure your ESM wires are all connected right and tight. Mine did this when one of the wires came loose, it wouldn't even rev past like 3,500 and idles horrible. When ever I reset the ecu it would go away, but when I would floor it I noticed that the VAFC read +0.01bar on the pressure sensor and this is not supposed to happen with the black ESM box. Try checking that first.

called vortech up and they told me to pull the whole blackbox out and see what happens, so i did but the car still idling pretty bad and cel still on. so i went ahead and scan the codes it read p0301 and a p1399. oh yeah and i was actually driving like this for a bit, don't know if this would hurt it more no not but vortech said it shouldn't. what should i do now either take the charger off then take it to honda or leave it on.

any input would he helpful thanx.
