Problem
Happened twice, turning right on a highway on-ramp...when i hit the apex of the ramp at 70-90km/h my check engine light comes on and my car kinda bogs down, like its choking..this is in 3rd gear...i got 100,500km on my car too, do i need to replace anything?

anyone know what this might be, clutch slipping? 02 sensor getting pulled? timing belt? i have no clue...

thanks in advance for any help

your VTEC might not have enough oil and is messing up because of the turn. are you in high rpms when you take the turns?

hmm, have you been taking proper care of your car? oil changes on time, tranny fluid, etc etc.

IF your o2 sensor is getting pulled rapidly in and out, vtec doesnt engage...no sure, but i heard about it on this site, so dont count on me for it. what im thinking is ur taking the turn at a high rpm. when u do, the o2 sensor gets outta place during the turn, vtec disgages and shuts down...causing your car to "bog down". that "bog down" feeling is probably vtec shutting off while the o2 sensor is outta place. again, this is just my guess, im no mechanic or havent even seen ur car. but you should check up on your car for any problems.
check:
oil dipstick
tranny fluid
BOTH, yes their are 2 (two) o2 sensors. one on header and one on cat
are your wheels properly mounted and balanced? maybe the right front wheel is loose and wobbles, lagging your car
what kind of oil are you using?
brought in your car for tune-up lately?

i'm going about 4-5000 rpms...maybe higher cant remember, but i'm sure its high cuase i'm downshifting into the corner...

check your connections on the o2sim, maybe the connectors coming loose and thats causing the CEL, which is mostly concerned with emissions...

Could be moentary oil starvation. Try keeping the oil just a "little" higher than the dipstick mark. I actually HAVE to run a quart extra in my nissan, or the pickup slurps air when I hit a corner hard. That's what baffled oil pans are for, btw.

Always try the little things first.

I had the Same Problem too. Try This.. take your car to a dead street. and run it..keep the rpm under 4K... it should run fine....now try going above 4k ..if im right your car should start spuddering or feel like a governer is kicking it...the reason is because there is one wire thats not on the diagram that comes w/ the apexi. its the VTM wire... its....on the second plug down from top......... counting from left to right top to bottom its the 5th wire.
