hey all i don't know where my low end torque went. If you find it please return it to me. no but seriously some days my na seems like its getting it some days it acts like a pig wtf.

 

are u sure your auxiliary ports aren't stuck open?

 

deff. check the ports but see about the erg . then again if it is the erg it well run rough and **** mostly like a vaccum leak .

 

erg? whats that, my ports are not stuck open but here's the thing i don't know if anyone elses na does this but from 1-3k it's slow then @ 4k it starts to pull but @6k it's like a kick in the pants then it pulls hard is it supposed to be like that or am i supposed to feel it pull evenly from 3800 to 6k? my ports are not stuck and i know they work b/c i pulled them and pressurized them and they moved. so if they are opening late what would cause this?

 

wooops im retarded haha EGR .



The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases.



got that from a site .. but if its not holding pressure it can cause a **** load of things . stalling, bucking ,lack of torque / power. i thought it was the horrible 3800 stumble but that"s more of a hick-up . but what ever. you can block it off with a plate . it's located on top of the mid housing under all that fun stuff called the dynamic chamber . try to get a hold of a haynes book for the car it helps.



you can also remove those rotating valves you were asking about . you loose little lower torque , your top end gets a little more power but nothing to go all crazy about .



my 87 n/a ran great with the egr blocked off and the valves removed

 

side note you have a 90 so things might not work like said . your engine is set up alittle different

 

could an exhaust leak cause this problem?

 

nah .. not leak anyway . how is you exuast system anyway ? stock cat or custom? . is it hot or cold when this happens?

 

seems to happen more when it's warm. stock cat stock exhaust with a huge hole in the pipe before the muffler. i thought the cat might be getting plugged so i'm waiting for my test pipe.

 

My S5 n/a feels like that too. Some days it kicks *** and others it feels like there is no pick up.
