Now I ran 12.8 with the car untined and I only took it to the track once tuned and with 100more whp then untuned I ran worse times but my MPH were up so I figured that I was spinning more BUT I also noticed that it felt like the car was holding back every so often down the track. Like it would pull REAL HARD then stop then pull then stop.

Anyways I though then that it might be the mix of the C16 (116) gas with the little 94 that was left in their of maybe my honda chip was gone. Drove back to Ottawa and had zero problems with this cutting in and out NOW while I was at DARKNIGHTS in toronto,

Im on the 401 and I drop 5th to 3rd at a safe RPM and punch it and car is dong it again. HOLDING BACK, it last from sometimes 2 to 4/5 seconds and its right back at pulling hard again. So I have been playing with it all weekend and it is doing it ALOT MORE NOW. It happens anytime I punch it at a higher rpm, 2nd, 3rd, 4th gear. It will pull very hard then just stop pulling as hard and go back to pulling hard again. MY AIR FUEL IS PERFECT, MY BOOST ISNT DROPPING, but the car is DEFINATLY HOLDING ITSELF BACK for those moments. Also the sound is changing from that hard spooling to barley at all while its still boosting at the same level. The sound is like no vtec to vtec. Its like its on then its off. I have no engine codes either. I honestly have no clue what it is and hoping that someone here has experienced the same problem or heard of it. It has just started happening more and more recently. I cant even race bikes no more cause she just doesnt pull hard the entire time.

The plugs are good NGK's and were changed at beginning of summer but I was also using them while running untuned and very rich and the wires are from last summer while I used NOS all summer/no turbo. It might be plugs, it might be wires, could also be my cap but please anyone with ideas, let me know.

I thank you all very much for helping me out!

oil.........??? How is the oil?

 

Oil is mint! I run 20w50 and never had a problem with that!

I ALWAYS check the oil.

 

ttt

someone has to have a good idea or better yet KNOW???

 

Have you checked for codes? ECU's have at times thrown codes without the check engine light.

 

Done, I checked for codes while at the shop eariler.

Alright. I took out my plugs and they are the brown/grey colour and have slight electroid wear so I'll replace them anyways I guess. I took off the car and the rotor seems to have a slightly none smooth edge and looks a little darker in one area then all others so I guess Ill try replacing that to, as theses are things that would only be affected onder heavy load.... ie: Boost at higher RPM!

Anyways any help would still be thanked very much!

 

Check for cracks or carbon tracking on the inside of the distributor, better yet replace that too. Do you have and ingnition system. Could be and ignition module going out.
