missfiring on boost .
 

my dohc zc is misfiring on boost, and at wot at some rpm out of boost. ive tried leads, new plugs, ecu,.. thinking dizzy ? fuelling?

any ideas. i can get a vid of what it does.

Re: missfiring on boost .
 

try another dizzy, and check your timing on ecu.
What type of management do you use ? ( and spark plugs ?)

Re: missfiring on boost .
 

try tuning it..

down size ur gap on ur spark plugs

Re: missfiring on boost .
 

its a dohz zc with a halfassed street tuned map, has been running fine for about 600miles.. spark plug gaps sweet, the fuelmap is sweet, i ll hava fiddle with the dizzy 2moro.

Re: missfiring on boost .
 

what gaps are you running your plugs at? "sweet" doesn't really tell us anything....

Re: missfiring on boost .
 

Just add more sweetness and the problem will be fixed. ::)

add some more funny jokes fukweed..


gap is .9 i think... the gaps sweet as i said. ive run heapsa boosted hondas on stock gap with no worries

starting to fuk me off cause i cant rape it.

im guna try a new ecu 2moro, clean dizzy cap , .

is there actually a way to check the fuel filter or does it just need to be replaced.

to clarify it abit more, it runs on 3 when on boost, its not a random missfire, just always runs on 3 and its the same cylinder that it misses. off boost it drives as normal , unless i floor it and itl random miss.

.9 gap...um...is that metric? try .020-.025 inches and see how it works. I'm too lazy to try and convert your number... Nect thing, try swapping injectors around and see if the problem moves to a different cylinder. Have you tried a new distributor cab? How about new plug wires, or atleast swap the wires around if they're long enough.

BAAAAAHAHAHAHAHA!!!!! Glad I wasn't the only one who thought "sweet" as a setting was pretty hilarious. LOL. Oh my. LOL. I love it.


Holy cow!!! .9???? What the heck?!?! HA!
