my car has done this a few times now, heres what its doing, when i shift from a lower to higher gear at around 5 to 6k rpm it will shut everything down, cel comes one, wont shift past 3k, doesnt boost at all, and my access port shows no trouble codes?? but once it cools off it shifts fine but cel stays on, still no code, and once i cool off the second time cel is off and runns fine untill the next time? its done it like 4-5 times, any ideas?

i took it to gst and they said it has a vac/boost leak, could that be the cause? they also inquired that i should be running a fmic, car has roughly 320 to teh wheels, bigger turbo all required upgrades for it, exhaust, intake , big maf injectors ect.....

any ideas? could the boost leak be causeing it to do that? will a fmic fix the problem?

any help

 

doesnt have to be a fmic. you can just get a bigger top mount. there is someone on iclub selling a spearco tmic that might beable to help you

 

why did u post this in the classifieds?

 

hmm..I have no idea. Still run stock bcs? I think you might get better answer at tech forum.

 

well this is in the wrong place to be posted.

Whats your setup? Has it been doing this since you bought it?

 

forgot i was in classifieds, how do i delete new to this forum?

 

check your boost. theres a vacume line that runs right above the turbo and gets worn fast. if it goes youll have uncontrolible boost. feels good but damageing to the motor.
