I am throwing a code 4 on my 88 Civic Hb with a b16. The fires up fine but it won't go pass three grand and runs like absolute crap. Like it's lacking power. I haven't driven it I just tested it on neutral. What does code 4 stand for. I heard it's cps and someone said something about replacing the whole dizzy. Any help is appreciated.

 

 

OK I'll have to check my dizzy then. Do you know if a B18b1 dizzy will work on a b16a

 

yes

 

i am leaning towards a bad ecu however. My ecu just burned one of the circuits and I bridged the burnt part with a wire. Car was running perfect before this so I will first replace my ecu before I eve check the dizzy.

 

where does b10 and b 12 run to in the engine bay ?? i checked the resistance there and got no resistance..

this is on my 94 gsr turbo.. and its getting frustrating..

 

my car started throwing a code 4 when the weather got cold. exact same problem where it would run and idle fine until hitting 3000rpm. i ended up replacing the brand new dizzy which was under warranty and it runs fine now. good luck.

 

what is the dizzy? I see this and dont know what it is. thanks

 

a 'dizzy' is a distributor i had to ask the same thing when i started on here

 

i was kinda thinking it was but didnt want to look stupid. Guess i do now though oh will i got the facts lol. Well on the subject, my dizzy went bad on me. I am wondering if that is what was causibg my dyno runs to be shitty.

 

well swapped my dizzy out with a new one from my friends car and it did not take the code away. swapped ecus with his and it ran fine. what can it be my ecu?
