just thinking out loud, but I would maybe check your spark, see if it's dropping out, fuel pressure.??

[Poggy]

What boost are you running?, if you go above 14.7psi you will max out your map sensor and trip the fuel cut which will cut injectors. Best way to fix this is a fuel cut defender, $25 from jaycar, will alter the voltage from the map sensor to the ecu so it wont think its running above 14.7psi therefore wont cut.

ok
but mine is afm would that make any difference it does the same as
urs did on the you tube vid

[.:2DR-FTU:.]

could be droppin spark under heavy load which could be coil related, or yea, a fuel pressure problem. If you can rev it above the 4000 freely when in neutral id say coil packs. I had a similar problem in mine, and yea, a set fixed it right up :-)

[squirt01]

thanks 2dr-ftu
could be the coil cause it has new plugs,leads and yeah it revs over 4000 no
probs. ok wish me luck tryin to find some (any replacement,or a/market one i could get) thanks

[.:2DR-FTU:.]

um funny enough ive heard of ppl using excel ones with there aftermarket computers as a budget change, but thats on smallport versions. Ring sss automotive in sydney if your out of luck trackin one. If they have one ill go grab it and post it. I know they can be a pain to track down...

Check your AFM wiring buddy, if you dont have an ECU related problem i would def be putting my money on it being a wiring issue.

So its only cutting at a certain RPM, doesnt do it under any other condition (ie isnt affected by eng temp, intake temp, load etc etc) ???

If so i would be taking a good look at the AFM.

[TERRA Operative]

A set of coilpacks are being sold on twincam.org

[squirt01]

hcope86 yeah its under load could get another afm (hopefully)if need be..
terra op thanks buddy tracked him down the coil pack should be in transit
tomorrow 2dr-ftu thanks mate i could be one or the other if its not the coil
ill have a spare ha ha see how i go on the weekend...
