Alright im going to make this as simple as possible...at times whether im driving easily and cruising or getting on it my engine temporarly looses all power then comes back to life and sometimes it will happen multiple times and then it will finally throw a cel but it doesnt show a code....when this happens I can sometimes shut my car off then secure the fuel pump (killswitch) crank it to burn out excess fuel then turn the pump back on and then it fires right up often clearing the cel.....does anyone have ANY idea as to what it could be? The only thing I can think of is a faulty ignition system....car has a b18c (stock compression) and some head work tuned on s200

 

will the check engine light blink? last time you did a tune up?

 

No it doesnt when I jump the harness the cel turns off and doesnt blink

 

I replaced the dizzy about a year ago with one from distributer king and replaced plugs roughly 6 months ago

 

year and model?

 

Same problem here, I thought I was the only one...

mine is a 95 Civic EX stock.
new plugs, wires, and dizzy.

 

^^so when you jump the service connector, no code flashes?
but while driving, the cel is illuminated?

 

Correct

 

hmmm. weird. do your clock and radio presets all keep memory?

 

yes

 

Yup they do....im so lost right now...i was talking to my friend and he was saying something about the fuel pump but im not sure how it could be...if it was bad wouldnt it consistantly run like crap

 

bump:

 

oh wait, i think i found my problem...... bad o2 sensor!!!
I will look into it and report back later what i find.

 

Yes please do...i think it could also be a fuel related problem...specically the pump but if thats the case then why is that when the CEL is on it doesnt lose power can anyone answer this

 

^^so when you say the engine loses all power, what happens to the operations of the gauge cluster? like tach and instrument panel lights. does everything die?

 

Nope...i am pretty sure i found the issue...IACV i unplugged it and the plugged it back in and cel was gone...pulled it off and cleaned it really well im about to go home now so ill know if thats the issue...i after finding the problem i went online and a symptom of a dirty or bad iacv is intermitent powerloss while driving...*crosses fingers*
