Been in the garage since 2018! Started with bad halfshaft seal and one year later of storage, the infamous drivers side fuel leak. I ordered the stainless pre-bents and never put them on. Had it towed to a trusted shop. He suggested a splice, but decided to replace the bad section with my stainless. Fired right up, ran like *****, but i let it go through the warmup cycle and it smoothed out. On the way home, got p0327 (knock sens) and p0013 (actuator) went into "engine power reduced" but would still let me free Rev to 7k+, but when in gear, right before the power kicks in, bogs down and cuts off the power. Also noticed the fuel pressure on the pillar was cycling around 800, i didn't notice til i hit the driveway (20 minute drive) that the fuel pressure display is now blank. (Stopped to fill tank with premium and dumped stp fuel system clean in it (they didn't have seafoam) any suggestions? Been in my cement floored garage since 2018, up off floor, near mint still at 129k

 

First, if your car says "REDUCED ENGINE POWER" why would you go and rev the p**s out of it? The ECU is trying to stop you from destroying your engine.... Just doesn't seem smart to me.

Now that that is out of the way....

Sounds like you took a car and stored it for 6 years. Hopefully you got the intermediate shaft sorted out, and sound like you got your fuel lines sorted out. The initial issue is probably bad gas, 6 years sitting probably not good. The p0013 for the cam actuator solenoid, not a huge deal they go bad. Probably not a bad idea to change both and your oil. For your fuel pressure, I would imagine you get some type of code for low fuel pressure, if there really was an issue. With the fuel line corroded, I would not really surprised if there was rust sent through the lines to the high pressure fuel pump. I could be mistaken but I think the only place the fuel is filtered in the LNF is at the in-tank fuel pump, so if rust was sent through the system after that it could be clogging something up, like the HPFP or injectors. Again though I would think you get a code for that. The p0327 for the knock sensor is probably why you are going into "limp mode" That code is usually set when you have bad sensor, bad/broken/shorted wiring, or could be a bad ECU.
