Today my car was working pretty good, I was driving down the road, was in first gear, at the end of first it made a pop sound like it always does just randomly. I thought nothing of it car still felt the same etc. Well, I get back home, tweak a few things that needed tightening down etc and now the car doesn't feel like it's boosting at all. My exhaust has a hole in it where an aftermarket wideband? should of gone in. I had put a screw and washer in that hole to seal it up but now it's rattling and i can see it's visably loose. The hole is up about a foot and a half maybe from the turbos themselves.

Would that being loose cause a huge loss of power? I know what a blown motor feels/acts like so that's not something im concerned with. But it really doesn't feel/even sound like the car's turbos are even doing right now. Anyone have anything they could throw out there that I could check possibly? Post up, thanks.

I thought I had half of these things gone now they're back again with a vengance? Someone clue me in would you?

And my speedo doesn't work but I replaced the sensor .... anyone have any ideas on how I can fix this issue?

Im pulling codes

I dont think that would cause a power loss it would just be letting more exhaust out quicker if its unscrewed, so if anything that would make your turbos spool a tiny bit quicker because of the less restriction, think midpipe vs. cat.

My car did this once and i just had a few loose intercooler pipes and the flat looking pipe coming off the y pipe was loose where it connected.

Mestre

yeah i thought that too but none of those pipes are loose now Highly damn annoying as I wanted to go out and enjoy my car with my girl yesterday then the car just doesn't have any kick. Grrrrrr.

Replace cat with a high flow. Check your couplers. Any other unusual noises? What's your boost pattern?

It wont run right without an o2 sensor. Get a damn o2 sensor. Why dont you have one anyway lol?

Mestre

it's an hole for an aftermarket WIDE BAND sensor, not an o2 sensor the car wouldn't even run without one i don't think.

And im running non-seq, I have a full exhaust so that stuff is all fine, it just randomly did this the other day so i'm trying to figure out what the issue is here.

I don't have an o2 sensor and my car runs better than with one.

Mestre

welp, if my engine still "feels" ok, then lets track it down, possibly turbos? And if that were the case, what exactly would a blown turbo feel like then?

Are you sure you are reading the codes right?

If that code 6 is really a code 5, that would be your power loss.

Mestre

yeah because it comes/goes as does my speedo heh.

Changed the cabling for my MAP sensor plug as it was all hacked up before, that code 13 doesn't come up anymore but still no power.

i had the same problem and i changed my spark plugs, the problem went away. I did a vac hose job with silicon trying to fix the problem and it turned out to be spark plugs lol
