A week ago i was running on a trackday.:drive:
After a few rounds my low level fuel flash on ,the fuel needle saw's i had some fuel more (1/8) on my last round and when i was accelerating from 3rd to 4rth gear, engine lights on and engine cutout of power :angry:,i immediately let off the gas pedal and engine works just fine.
I went out of circuit and refuel.
After that incident i noticed that when engine get on vtec on 5200rpm its delayed to make power ,engine sounds more loud than usual and power is very poor, engine can't reach limiter an a strange sound comming from the bottom off the engine (like steam getting out of a kettle) on 7000rpm.:nono:
I don't get any cel code
I didnt have any strange big tempereture on water driving on circuit
I did had some oil consumtion but refill it
I change my fuel filter (that it was very dirty)
I put 200ml of fuel system cleaner on the reservoir that have on about 20 lt of fuel,
I thought it could be fuel injectors?
but the problem stays. I didn't consume all the last fuel yet.
What do you think guys? is it the fuel injectors or something else?:((
 
even though your CEL came on you don`t get any codes when you inspect your ECU? afaik when CEL comes on, error stays in ECU even with CEL off.

I thought engine light came on the time my engine cut off when i was running on 110 km/h and when gas pedal was on the floor, i imediately let it off , the engine lights off and engine worked again but from then i was going slowly till I refuel!
No i didn't check the CEL code yet!
 
Yesterday i took off vtec solenoid to check vtec filter, but vtec filter was real clean!
Today i made a compression test to see for a piston ring ware!
measurements as follows :
1. 15,5 bar 225psi
2. 14 bar 203psi
3. 14,5 bar 210psi
4. 14,5 bar 210psi :nice:
On 1 cylinder run some oil from valve cover when pulling out sparkplug ,that's why had bigger compression.
next step is to try some other fuel injectors in case mine where stuffy.
what else do you thing i must check?:(

A few days ago I took the injectors and clean them.
I reinstalling them but nothing change!:((
We thought that maybe the catalytic converter is clogged and unscrew the screws before him. I made a car ride (did incredible noise) and found that the car finally worked differently, it was like another car.
Engine's power finaly took off!:drive:
Now i understand the strange sound coming from the bottom off the engine that seemed like steam getting out of a kettle!
(On high rpm engine produces so much gasses that could not pass from clogged catalyst and escaped from link before the catalyst and sounded like that!)
So what do you think,I should go for a new catalyst or go for a decat?:naughty:
 
Baffled de cat :)

Something like this?
