Wierd Problem READ PLZ

[racer]

I have someting like this too but im N/A.Expecialy when i havent driven the car for like 3-4 days.For example I drive on 2nd gear with like 2000 rpm and sudenly I hit the accselerator and the car will bog or miss 2-3 times.It feeels like it wont grap and the tires are spining like there was a little rock or someting under them.It feels like when new driver try to drive a stick shift and the the car shakes cuz of not properly reliesed clutch.I hope that explanation is enough.My idle too when first start the car if it goes normal all of a sudent it ll be like rrrrrrrbourrrrbou like missing or someting.Then when it worms up doesnt feel that much.The car is very powerfull.No problem with the performance.(mods at profile).
If someone can help plz.I also cheked the ECU and "Stepper Motor" all fine.ISC is new.Engine has 123 000 on it.

Sounds like it might be plugs/wires related?

Yeah, definitely sounds like its within the ignition somewhere. When was the last time you changed the O2 sensor and/or PCV valve?

I change the O2 like 6-8 months ago and PCV valve like a month ago.
The O2 sensor was universal so I had to manualy connect the four wires,but it didnt have that problem befor it started doing this from like 2 moths ago.I use BOSCH O2 and PCV from "DISCOUNTAUTOPARTS".
Im sure it is not from PCV valve cuz it did that with the old PCV,with NO PCV and now with the new PCV.I have 8mm aftermarket ignition wires that are like 1 year old with like 4000 miles on it and NGK plugs that are like 3 moths old with like 7-800 miles on them.We cheked them and they all seem to be fine.My mechanic couldnt figure it out.All he said was well I duno I gess u should get new ECU and try to see if it fix the problem cuz I dont see any reason for it acting like that.Maybe I need to find new mechanic.

Have you checked the fuel delivery system? Rough idle and stumbling on acceleration are signs of a faulty fuel delivery part. Check your fuel pressure, use a noid light to test your injectors and change your fuel filter.

well my fuel filter is like year old and it has prolly like 4-5000 miles on it.I dont think it is bad or cloged cuz I use only 93 octane + boosters and fuel sistem cleaners almoust every tank.I still have the stock injectors (never been changed).Im going to check my fuel preasure this week and see what is up there.I'll give update here.Thanks man.
