Hey everyone! I have been having this fuel cut at 5-6rpm with a flickering cel and its goes off on my b18c1 turbo civic after my recent tuned. It usually happened on third/fourth gear before the vtec engaged. I never had this problem until i took it to the shop to dynoed. I have try many varies options by reading a lot of honda forums but seems like i cant get it to fix. I have try swapping a new vtec housing/solenoid, new distruabtor, 255 walbro pump, and i still have this problem. Also, if you floor on low boost you are able to hit 8, and vtec engage but at the high boost you can't hit vtec nor pass to 8rpm. One thing i notice, if you slowly step on the gas you are able to pass vtec and get to 8rpm on 3&4th gear..but if i floor ill get a fuel cut at 5rpm before vtec engaged. Also, i realize my lanuch control is not steadily, it will bob up and down.. Like crazy. Please help!!!!! Ill appreciate ur help! Thanks

 

Pull. The. CEL.

 

Once u hit fuel cut it will shoot a cel then goes off. Idk how you would check that cell when its off?

 

Keep the car running and pull it.

 

Explains?

 

How do you NOT know how to do this at this level of car modification?
CEL comes on. Pull car over. Leave car running. Jump service connector with a paper clip. Record the flashes. Some short. Some long.
Check codes against list found at this link

If you have a code reader even better.

 

I think its only use for check engine that are on. My check engine isnt on, but once the fuel come it will shoot a cel and goes off.

 

Help!!! Bump!!!!!

 

Follow the previous advice.

 

Maybe your tuner set your rev limiter to low ad the cel is a shift light if it only comes in then?

 

What program are you tuned on? Do you have adjustable FPR? Go back to your tuner and explain to him whats happening.

 

PLease see your tuner. If you didnt have an issue PRIOR to tuning and your having it AFTER the tune and it so happens that its happeing at vtec/crossover engagement, then he probably forgot to push a button or something. See your tuner. It might just be some thing small....
