anyone?

hi guys, well i had a fault code of p1086 which was a sticking tgv passenger side, so i bought a second hand set and made sure they were free from all carbon build up etc, they moved extremely freely. the mechanic forgot to pre tension the sensor after fitting and it still ran in limp mode. once pre tensioned on the left hand side it ran perfectly.......... for about 10 minutes!!them limp mode again!!so we plugged it back in and it now has a fault code p1091!!tgv again!this time the right hand side stuck closed!!he cleared the code and the car ran perfectly again for a while, but then again limp mode. my question is : if we clear the code and it runs ok, means the actual valve cant be stuck, right? so does that mean that the sensor is dodgy? any help advice much appreciated, thanks,steve

im pretty sure its not, as when you take off the tgv sensor, theres definitley something that runs through the tgv's and can be moved with pliers.so the flaps are still in there.im hoping to get it to him in the next 2 or 3 weeks,when hes up this way again.its proper frustrating though!!

thanks for that phil.interesting read that, looks like less messing about to just change the complete manifold. its weird though, cause my manifold is red! prob just been painted though ha

when i had it in for poor running, it threw up the code p1086, passenger side tgv actuator low effort. the guy said it will be the actual butterflys sticking. so either way i need to replace or delete. got a standard set coming, but not convinced the guy i got them off wasnt having the same problem to swap his for sti ones.but well see.... im still on the hunt for sti ones myself, and dont really want to buy a full manifold,fuel rail etc to get them, as the ones i have found wont seperate them from the manifold grrrrrr....

so what model will have the ones i need without having to butcher the oem ones?gonna be getting a guy called duncan from race dynamix to map it for me.just waiting for my exhaust to come, and get this really annoying problem fixed!grrr...

ah,cheers guys

hi all. should there be 2 throttle cables under the bonnet of my 02 wrx?thanks,steve

yup sure are!got a set coming, might butcher them before they go on, as its getting mapped in the next 2 weeks anyway. it is a bit of a mess about, but i believe the newage sti's dont have the tgv's, and the lifters/risers call them what you will, are a direct fitment??been hard trying to source some though!!

a maf sensor can fail without throwing up a code, you can get a cheap second hand one without going to the main dealers, and it would be the first thing id look at

i found that on my old import, and it was alot better with a new good quality battery,not that youd wanna spend 70-80 quid just incase

just a quick question to settle some arguments im having with my old man.when it comes to the tumble generator valves, what are the related pieces?i.e are the butterfly valves(like a throttle body)the tgv's?and if so what are the other bits- the tgv sensor actuator, and whats the other thing under the intercooler on the back side of the manifold on the passenger side?oh.. and should i have 2 throttle cables under there? thanks in advance,steve

ive pretensioned it,now defo in limp mode.what would you do, get the actual tumbler valve or just replace the sensor/actuator?cheers,steve

probably go better than mine at the moment

im counting down the days until payday so i can actually get my car sorted.but ive been thinking, the guy at well lane said it would be the actual flaps that were sticking, but theres a different code for them being stuck open or closed. and i also didnt know that the sensor had to be pre tensioned before putting it back on. so im gonna try this incase someone has had it off before. but if the only code is p1086 tgv low input, do you guys think if i just replace the sensor/actuator it will cure my **** slow car? cheers,steve
