Took er up to 90 today started protesting like she was "missing" eased back ---ok,welly again started protesting again, no problem up to 70-75 tickover is good.What could cause this to happen when under "LOAD" at that speed?? :mad:Any help would be great!!

 

chaZ:confused:

did you get this sorted? exact same problem to mine

Fluctuation of air across the induction kit.

 

If you have repalced your air box with a cone filter, then at speeds the air will be forced into the filter. This is only usually apparent when you are lightly on the accelerator and trying to maintain speed rather than accelerate.

 

If it happens when you are trying to increase speed then it's not likely to be caused by this.

 

If it does sound similar towhat I described above, have a read up on making a wind guard for the induction.

It can be early signs of an auto box about to fail. The "missing" sensation can be clutches slipping momentarily when the load is upped on them.

true but if that was the cas and i still had foot on the pedal the boost gauge wouldnt drop half way into the - (negative) it is definately a miss or a leak.... like on my other posts santa has seen both of my actuator pipes are undone where the old member took off the boost controler and left it.

 

drives fine but under full boost the car stopps pulling for a second and then the boost builds up to full again .

 

the only thing that causes me to worry is that other people who had their wastegate connectors off (with no EBC) didnt seem to have this problem... yet my plugs are new and fine, injectors and coil packs are fine and maf and PTU are fine.

 

can't tell if it is a leak or a miss however even though santa says it is the wastegate pipes seeing other people in same situation have not confirmed having the same symptoms ... so now i wonder what else it could be

did you get this sorted? exact same problem to mine

 

Hi mate presently don't have a Z SOLD ER anyway yes I did sort the problem

but can't be sure how,as I got fed up and changed air reg valve IAA valve TPS

AND plugs problem went!!!!!!!!although when I changed the plugs I found that one of them had a big crack in the ceramic part ,could well have been that!!!!!!!!Hope this helps:hyper:
