So I took my 06 V8 out for a drive today since I haven't drove it it two weeks. I drove for about 4miles not going over 4500 rpm to warm the engine up. After that I got on it taking the rpm all the way to 7000 1-3rd gear then back down, when I came to a stop sign the car stated to spotter like it is about stall then a msg popped up on the dash engine power service Urgent(might be mis-quoting but it was something alone those lines) I try to press the gas but it would just spotter moving like very slow and jerky. I turned the car off then turn it back on but it just cut off right away again. I sat for a few mins then turn it back on the message disappear and i start driving slow so i could get back home. I got to a stop light about 100feet from the first stop and it started to spotter again then the engine light came on and now a new message on the dash reads emission service required. I then stopped again for a few mins check under the car turned the car off then started it back up move 5ft but still spotting so I decided to stop give it a few mins to cool down (during these few mins which felt like an eternity deciding should I call a tow truck but in the back of my mind I'm think this has something to do with the cats install not an engine failure) I decided try and make it home, I started driving very very slow 20mph I didn't get any spotting and my goal was to try to get home. So I made it home driving 20mph without any spotter.It wasn't until I got back home I also remembered i haven't drove it since the filter upgrade also. (Lights and msg still on the dash).

A little background two weeks ago is install some high performance air filter from Vcollection but haven't driven the car since its been install except pulling it out the garage and in twice. A month ago I install some Ken Harrision high flow 200 cell cats (same ones as 007 just installed on his and did a write-up) but i've driven the car about 4 times at high rpm since the cats been installed with no issue.

Tomorrow I'm getting a Eurocharged Remote V2 tune. This was part of the reason for taking out today to have a comparison.

Anyone have an idea of what could possible be the issue?

I'm hoping the issue is the engine is trying to adjust to the upgrades I did and the tune should correct it.

Thanks for your feedback.

 

Definitely NOT an expert on AM cars, however Merc's AMG's have a similar problem with K&N filters. The oil on the totally screws up the Mass Air sensor and that causes all the lights and the sputtering. The comps cannot figure out how much air to fuel and it drown it out one way or the other. I am willing to bet if you take the filters out and return to factory the light disappear. However you may have oil mist in the Mass Air which won't change unless its cleaned out. Not diff to do. THE ONLY issue here is I honestly do not know if the AM's have the max air. I am pretty sure they do, just would hate another member calling me on that. Would be embarrassed. The Oils in the filters need to be drained by laying the filters out for several days and wiped and allowed to drip it off. Then sometimes they work. Several companies have High Flow filters with no oil. There is a big debate about this for many cars. Do they help???? or do you get about the same as a OEM paper one. I know the tests and theories but one of my AMG's took K@N's easy, the other threw codes. Same year , same E63. Just thought this might lend an better understanding to the possible situation. Could also maybe be a Oxygen sensor in the exhaust. But start with the Air Filters.

 

Thanks SheriffDep for your feedback.

I have read about the oil and the mass air sensor debate issue. The filter I installed had very little to no oil on them.I had no residue on my hands when i was installing them and I investigated the filter carefully before I installed it for that reason. Being that I haven't driven it since I installed the air filter I don't think that would have affect the MAF sensor with in a 4 mile drive. I'm hoping its just the engine not able to correct itself with the HP filter and the cats install without a tune.

Hoping its not an 02 sensor because they seem hidden under the heat shield above the cats and they were a bit tricky to remove when I was removing them to install the cats. I've done a few on my NSX one recently but I'm sure these would not be as easy.

 

Update,

So i was on my way to my AM tech car driving fine normal speed, had to make a few stops and on my last stop off to get gas turn the key and no check engine light or emission service notice on dash. I wanted to get the code check anyway and these were the codes pulled.

P0106-Manifold absolute pressure/barometrio pressure sensor range/performance
P2106- Throttle aotuator control system-forced limited power
P2195- oxgen sensor signal biased/stuck lean bank 1 sensor 1
P2197- oxygen sensor signal biased/ stuck lean bank 2 sensor 1

With the extra air flow guess the engine couldn't comp without a tune running the rpm that high, working one getting my tune done now so this issue doesn't happen again.

 

No way just changing to high flow filters will throw all those codes
Looks more to me like oil contamination as ALL the faults are related to sensors

 

Sounds like your car went into limp mode. It does that when it encounters a situation where it shuts itself off to prevent something catastrophic from happening. Mine has done it a couple times: once when shifting from the top of 4th gear into 5th and once when dropping gears when diving into a turn after the long straight at Summit Point. I'm guessing that I was being too aggressive and accidentally over-rev'd the engine. Both times, I pulled over, pulled the key from the ignition, waited a bit (maybe 20-30 seconds), then turned the car back on and drove normally. If you don't give the car enough time to rest before trying to drive again, you'll still be in limp mode (you won't be able to go over 1500 or 2000 rpm, or whatever the limp limit is).

Are the V-Collection air filters oiled? I didn't see anything about oiled filters in your original post. Personally, I refuse to use oiled filters. There's really no reason to use oiled filters when dry filters work just fine without the risk of contaminating the MAF sensors. Just my opinion, of course.

If you want to check your MAF sensors, here's a how-to guide. You can follow the steps to clean the MAF sensors as well.

V-collection filters are not oiled, it was fairly dry when I installed it. I know I didn't it the rev limit it was between 6000-7000 rpm 1-3rd gear(what a beautiful sound), the rev light on the dash did not come on which I've seen on previous drives.
I'll see if the check engine light return after my tune and a few high rev drives. If so I'll take them out and wash the filter and clean MAF sensor.

Thanks for your feedback.

 

Hi,

I have the Ken Harrision high flow 200 cell cats installed on my Vantage 4.3 liter 2008, I did more than 1000km and no problem at all, probably the air filters are the cause on your car

 

I know it's not the cats. I had those on for 3wks with no issue high revving prior to filter install. This was my first drive with the filter install. If there were any moisture in/on filter the Florida heat will dry that out in no time.

 

No changes to the car
Just on hyway and it went off
Did the reset by pushing the two buttons (t1-2) and read button
Until the triangle blinked 3 times

The emissions warning is off but engine light still on

Any clues ?

Gas cap tight 😊

 

Restart and the emissions light
Came back on and won't turn off

What do guys think it is ?

Runs fine

Actually at the track giving rides

 

if was serious (harmful to engine if continue running) would go into limp home. Sounds like just a fault with detriment to emissions output if you are driving and feel no adverse effects. Can you get hold of fault code checker and read any Pcodes?

 

Im looking for the reader now. after coming back from a driving event, where I actually ran the car for a session on the track. ( giving students rides). I filled up at the gas station down the road and I start the car up and now there is no emissions warning or engine check light. weird.


Ill have to get the reader on the system and see if there are codes stored.


maybe that other poster was right, it might take quite a few miles to get the check light to go out, even when something like a loose gas cap is the cause.

 

Gas cap is a common one, but DTC codes are going to be your friend here.

 

Were you up at Thunderhill by chance? Was just there this past Monday for the first time (T-hill west and first time with the car). Would love to chat offline and maybe get some instruction/ride-along to learn more about these cars!

Hope the light goes away! Mine came on while driving back to the bay area after a full day at Thunderhill.
