LTH with HFC + CBE = ?

I pulled the codes at Autozone today and had 2x P0300, P0171, P0133, and P0153. Can these all be attributable to my exhaust? No more than 40 miles later, SES is on again.

For the P0300 code, did you handle the MAF sensors at all when you installed the AEM intake?

I had that code up until I cleaned the MAF sensors.

I haven't installed the intake yet. When the SES light kicks on, I can damn near guess when it's going to do it just by listening to the idle. If the idle fluctuates too much, it kicks on. It's been doing it since the install. The shop says when they lengthened the 02 sensors, they extended the wires one at a time to make sure they didn't cross any of the connections. I also told them to remove the o2 sensors before they get crazy with the impact wrench trying to remove the stock exhaust and headers. When I was watching the AFR's the idle would stumble and shows running rich, then the idle would jump over 1k-1200 rpm and show really lean. These codes have so many reasons why they might have been reported, it's difficult to find out what caused them. I'm thinking of just throwing the rest of the parts on just to observe what happens to my existing issues...

Didn't Chuck have similar SES lights? I know he had the PPE longtubes as well.

Can you link the page? I haven't found anything yet

PPE Long Tube Headers Installed...

I won't look at replacing them until I get it tuned. Has anyone reported vibrations behind the firewall? Sounds like a heat shield buzzing from resonance at low rpm. I want to find it and choke it. I think I might try that resonator when I have a spare $150. I don't think it's too much out of pocket to see what the differences would be. The headers make power, there is no doubt about it, but I just want to finish cleaning up these small issues already!

Here is a new drive by vid. It may well rank as the worst ever lol. There is a plane in the background and the damn camera is pointed at the sky...... but it did capture the sound, so mission accomplished.

Woot! Monday I'm dropping the car off at Force Fed Racing again to get my oil cooler, NST Pulleys, intake manifold and CAI installed. I'll be taking it easy on her afterwards as I still need Uprev. I also found 93 octane fuel here in Vegas, I'm hoping that helps.

so does that exhaust setup drone at all?

It does between 2000 and 2300 rpm. It isn't bad off throttle, but noticeable when accelerating in a higher gear such as 4th, 5th or 6th. You can hear the drone in the video where I drive it around the block. It's at the end of the video where I'm coming off the highway going downhill. I try and show the drone. I usually just throw it in a diff gear, speed up or slow down if I am avoiding it.

Regarding the rasp, I think I overreacted. Now that I've been driving it more, I only hear it when the exhaust and engine is cold. Once at operating temperatures i don't hear it anymore. The big thing I'm fighting now is this vibration coming from behind my firewall. It's much more prevalent when everything is warm. It resonates and buzzes under 3000 rpm. It will do it when I come off the clutch and rpm dips and when I cruise at about 2200-2400 rpm. I have an audio clip but I don't know how to upload it.

The last video I took, I didn't know it sounded like that outside the car. It sounded surprisingly exotic. I don't think I heard any setup on these forums sound quite like it. In retrospect, I'm happy with it and think I'm pretty lucky considering the exhaust, Y pipe, and the headers are three completely different manufacturers. It could have sounded like a$$.

I'll be doing a dyno the night I drop it off because the weather warmed up a bit and I'm running 93 instead of 91 this time around. I'm not sure if it's a good idea to throw it on the dyno without a tune with all the parts installed. Definitely after the tune, I'll post those results

Car is at the shop. Should be done in a couple days. I'll post pics, vids and dyno results when I get them.

Quick update, just ordered uprev, hopefully I can get it tuned soon sooner rather than later

Was at the shop till 230am watching my mechanic work. Ran into a couple snags. On the back of the M370, there isn't a place to put this sensor that was onn the top right of the stock one. There is also a hole that we plugged up that looks like a line is supposed to run to it, but we didn't have any more to run. The mounting points were also a bit different in the rear, but everything is attached. Anyone have instructions for the M370 so I can verify everything is good?

The AE performance oil cooler kit I bought from a member didn't have the power steering lines to extend out, so I have to make a trip to Autozone to get some of that $hit.

We haven't gotten to the pulleys yet. We are looking for the best way to do them.

Anyone who owns an AEM CAI, did you have to take off the tire and liner to get the intake pipe in? It was being a pain in the ***. Besides space constraints navigating the intake tube down, everything is going in fine.

AE performance oil cooler... looks like hot sex. Pretty straight forward install. Missing two hoses for the power steering relocation, but that was resolved.

M370 kit was missing a couple fitting and hosing from seller (bought many moons ago), so we purchased what we needed and got that squared away. Besides the initial confusion... Very easy to install

Pulleys were about to start before I left. He was loosening the fan shroud to get to them. He also intended on removing the alternator and putting it on a vice to remove the alternator pulley. This looks like a pain in the ***.

Hopefully I can pick it up tonight. I only see him work after 5pm lol,

The AEM CAI and AE Oil cooler have some slight problems together. The windshield washer doesn't fit in it's new location because the big *** oil cooler is in the way. Oil cooler wins and the I'm removing the windshield washer fluid completely. I'll be picking up in an hour or two. Will post updates then.
