    I caught my 04 sti on fire!!!!

    So. I ordered the parts for the turbo oil feed line after i broke the stock one while replacing my turbo. I got everything back together including a shorty cone intake and the car wouldn't run with the maf plugged up, replaced it nothing. I decided to put the stock intake back on and now it runs again but won't boost past about 6psi like it's in limp mode. I pull the codes and get 1091 with the maf plugged in which is apparently the passenger side TGV position sensor, i unplug it and it runs exactly the same so i remove it to see if i can see a bent pin like i read somewhere on the forum and during that process i tried to loosen the braided oil feed line from the block so i could get to the lower screw on the sensor better but i couldn't get to it well enough with the turbo in place so i just toughed it out and got the screw with some extensions and a knuckle. I left the sensor off since i couldn't repair it and the new one is on the way(maybe this is bad i'm not sure) and since i'm down to 1 vehicle i unplugged the maf to take a short trip to the gym. i pull into the gas station(right next to a pump btw) and notice smoke, i pop the hood and my frickin engine bay is on fire!!!, a couple gallons of water later out of the store and i had it out, apparently i was able to loosen the fitting and didn't realize it on the oil feed line as it was over a quart low during a 5 mile trip and BURING...anyway that sucked any suggestions besides not be a moron on the other problems i'm having?

    After all that.... I'm still lost.. .Where is the fuel coming from ? The fuel rail underneath the intake manifold.

    It wasn't fuel that was burning, it was oil from his loosened feed line, if I read that correctly anyways.

    First thing's first, tighten up that feed line .

    If you leaned up against that TGV plug, you could have damaged the sensor, so replacing it is a good start. As for your intake trouble, you probably had the MAF in backwards, make sure the connector is facing the front of the car if you decide to try it again.

    I wouldn't recommned installing the intake anyways, because for all we know you bought one of those that is proven to mess with the MAF scaling, so, I recommend leaving it off, sticking with the stock intake and doing a silencer delete if the sound is that important to you.

    yep it was the oil, i already reverted to the stock intake, with the short pipe it wouldn't even idle and yeah the tgv sensor was definately violated, i had a 20g installed for 2-3 days and it didn't fit very well, it was a tight fit, so much so that i couldn't get the stock intake boot all the way on the turbo inlet and i'm sure all the attempts to get the boot on squeezing against the tgv sensor is what did it. it was a cheapo off ebay anyway, i found a low mileage vf39 and thats what i have installed now, i got the oil line tightened and thats ok and amazingly i don't think i managed to damage anything with the fire i guess my only question for you guys (atm)is does it make sense for the car to throw no codes besides 1091 and refuse to boost past 5-6 psi if the tgv sensor is trashed? I've done a bit too much driving with the maf unplugged during this and the performance has gone down in speed density mode so i'm assuming i probably need to do plugs now, esp since i've put 30k on the car (maybe 2k with the maf unplugged) and i have no idea how long the plugs were in before i got it.

    The 1091 is just a check on the position sensor, so if the sensor is bad then that's the only code I would think it would throw. If the motor was not capable of opening and closing, then you should be getting other codes as well, but if it's JUST the 1091, then I'm sure the sensor is just bad.

    What are you using to tune your car with all of this modification? Seems that you're installing and uninstalling parts willy nilly by the way the posts look, which I hope isn't the case.

    As for your MAF issue, are you certain the connector is on all the way and that all of the wires are still in tact, and not damaged, or not pulled back from the connector? Your car is effectively running in limp mode with the MAF unplugged, using only the MAP sensor for calculations, but I think you have other issues if you're not building boost correctly (I'm thinking tune).

    the car is now bone stock except for a test pipe inplace of the cat downpipe, the bigger turbo was only in for 2-3 days and i never was satisfied with the situation (not fitting)to get it tuned, it sat for 2 months before i found the stock turbo for 300$ and got it in. so atm the car is totally stock besides the cat downpipe is gone, unless the braided turbo oilfeed line is a mod

    sorry and to clarify i have the stock airbox back in and even a cloth filter! K&N is in the trunk took off the BOV someone installed, has the recirc back in business

    I checked resistance on the ground and voltage on the other wires, I wasn't super thorough but i was mainly concerned with a broken wire which wouldnt read any volts on the maf connector, the maf is actually not throwing any codes now that i have removed the cone and replaced it with the stock airbox. The main concern i have at this point is would you guys expect our cars to not boost/rev correctly with a bad tgv sensor? I guess bad plugs are a possibility at this point aswell

    problem solved, i was on the right track but the sensor wasn't the problem, it was the motor that operates the tgv valve, i just took a socked to the end that fits the sensor and turned the valve to the open position.
