Message comeing out on the dash were the options comes out "service enigine soon" no fault codes at all..and no its not the oil message..just wondering what can trgger this message to com on..I just got back my mail oder tune and is started doing this..
Mods..cai..long headers tube...no cats...
Who tuned it?
At first I was going to suggest checking the OPSU at the back of the intake manifold. But that would trip the "service vehicle soon" light.
I'm wondering if the tuner didn't set something properly.
OPSU??..the sensor in the back?Quote:

did they tune out your rear O2s?
Yeah. The oil pressure sensor. When they go, they leak and trip the "service vehicle soon" light on the cluster.Quote:

Yea as soon as the sytem is checked...it just start beeping a couple of time with the message..Quote:

So I'm thinnking that could be triggering the message??
About the code..I'm trying to trouble shoot what exactly needs to be fixed..I used to have an sd tune before and now running a reg..maf on tune..so I'm thinking the mass air flow sensor is not working prperly?? Anyone have any advide I can use..
I believe that code is for multiple misfire. I had that code. Check your wires as one could be loose. My issue was my #5 cylinder plug wire had come free from the spark plug. Found that and reconnected it and all is well. Did you check your oil lever and OPSU? You might be leaking from the OPSU. As for the MAF, if you're running the SD tune with the MAF, you could be having an issue, but don't quote me on that as my car still uses the factory MAF. Get back to us as soon as you can.
I meant I was running an SD tune before I got the tune from nelsons so right now I'm running maf...I did check the oil pres. But no leaks..still working on checkin each plug now..but to be honest the car is running awsome..I'm getting a lot more mpgs thn before..but I don't light that chk engine light :O...and even my transmission feels better..it used to kinda slip or sty stuck on a gear..now I haven't. Haed an issue since the tuneQuote:

on my gto when the service light comes on, my oil is ready to be changed. I set it to come on at 3500 miles.
You are getting better gas mileage because your car is running lean (not using as much fuel as it should be). Hence why you have the P0171 code (System Too Lean (Bank 1)).Quote:

Start with cleaning the MAF sensor with CRC cleaner.
If that doesn't clear the code, check for vacuum leaks downstream of the MAF sensor.
