evo x idle problem :(
hey guys, im new to the whole evo x forums considering i have had the car for for maybe a month but i could really use your help
i have a 08 gsr, the cars only mod is a turbosmart plumback bov.
so i turned the bov a bit to soft and when i hit the gas, the lid,spring and piston blew off, so i stopped the car right away, popped the hood open and put the spring and lid back on not knowing that the piston had shot out to. so i drove the car back home, maybe 1km and not reving over 2000 and shut her off, the next day i found the piston(it was sitting on my control arm) and put everything back together. i started the car and everything was great. then i was driving the down the street car when i placed my foot on the clutch while i was rolling down my street and noticed that my rpm were kinda low (around 400-500).
by the time i made it to the stop sign the rpm were going from 200 to 1000 (the car stalled a few times on me). This only happens when the car is completely warmed up, i also tried disconnecting the battery (didnt work)
so i took the car to a local shop in the GTA and got them to take a look. the couldnt tell me what was wrong but the did give me 3 codes that were popping up.
i did some reseach via this forum and found out that some idle problems are cause by vacuum line coming off, so i spent a good chunk of time following all the lines and they are all still connected.
here are the codes: u1417 implausible cooling data
c121c torque request
u0401 engine controller area network message
Ive learned now the hard way, if i don't no exactly what im doing then no to screw with things.
so if u have any ideas or suggestions please post them. Thanx for time evolutionm.net

Sadly I don't know the codes, so I'm not much help for you. However, usually when a car stumbles like that and the only mod you have is a BOV/DV...My guess is it would be a boost/vac leak.
Have you tried swapping back to your OE diverter valve and testing. I'm wondering if when things came apart it pulled a vac line off somewhere else.
