2006 STI Mods are fmic, tbe, fuel pump, sri..(ran for about 2 years now) 95K Miles...Almost made it to 100k It first started when I was coming off the ramp to merge and when I stepped on the gas it hesitated violently not allowing me to keep up with traffic but if I was very light on the pedal where the stock gauge shows no boost it would go. Its hard to start up and when it idles it misfires. When its cold it idles ok then when it warms up it dies. I hooked it to the scanner and it was showing that the car was adding 25% more fuel at idle? I do have an exhaust leak on the manifold but I don't know how much it could affect it. I took off the fmic and noticed alot of oil in the intercooler pipes. I haven't taken off the turbo yet because I'm still waiting for my tools to be returned to me but does this give anyone any ideas what it could be? Your pro-noob input is appreciated. XD
This probably has nothing to do with it but the turbo exhaust housing is cracked. I found the exhaust leak is actually just coming from the downpipe-turbo not the manifold. I think its the fuel pump but I'm an idiot for not trying that first...NUKE AND YOUR LIES
