right i have this problem if i accelerate from a low speed i get a poping sound (could be Det! :( ) from the zorsts, the car also will not pull even thou the boost gauge is showing positive boost! now this is the interesting part it dont do it all the time! only sometimes. Could this also be connected with the whisle that i can hear from the engine? could it be a leak in the inlet before the turbos?

 

Someone must be able to help me! please?

 

P.S. running stock boost. and ECU shows code 55 all clear

had a similiar thing happen on a reno 5 gt turbo, found it to be a blocked pipe.

cheers mate for the info but all the pipes are clear.

 

Just been out in it and its still doing it but i set my apexi boost gauge to monitor Boost and RPM gave it a boot funn and boost registers as 0.6bar but during the poping stage of acceleration the rpm had what looked like steps in it like a missfire. any ideas people?

Do you think it could possibly be a missfire?

it could be, but whats the cause? new plugs fitted, new ptu and all coil packs are ok

Just a check, but try bridging the det sensor with a 1MOhm resistor - WARNING this is a test only! Do NOT drive around in the car without the det sensor connected for any lengthy period of time - it is there to protect your engine!!!

 

Anyway, hope that helped lol
