Engine Light ON!?

So yeah second time taking the car out since getting the car back i think it was Sunday or next Monday, so driving the car home felt great, no engine light no nothing, washed the car, parked it in the garage, start it today 5/12/2018, I have an engine light on staying on.. im confused to what to do and what it exactly is, car idle and starts fine, sounds the same as before, louder, since the mods upgrades, but again, driving home and then a bit around town , and then parking the car and now starting it today, is when the light came on.


Mods that were added during this phase of mods listed below.


DSX Fuel System
AFCO H/E
2.5" Upper Pulley + Solid Isolator + Gates Belt

Reinforced SC Brick
Straight Pipes instead of Cats
D3 Reservoir
160 Tstat
Retune


No oil leaks, No Coolant leaks, No gas leaks.
engine bay to the eye looked normal no coolant smell or smoke or odor, nothing.


My mind is worried and boggled


Tune and Install by J-Rod Speedshop near me, 10/10 , 5/5 Shop, all positive reviews, great family ran shop and great tuner Matt Sorian.


So now idk whats going on, asking community for help or ideas.


Taking it to the shop on Sunday, for a check up, but any ideas might help as well.







*Update* Issue has now been resolved, thank you all for the input and specifically DSX about the FPCM, no light, and car runs as wondrous as before.


*Update* May 19th 2018, Issue of engine light came back even when I took it back to the shop for Retune of FPCM

If the light came on only after getting it back (or 2nd time driving) from the shop...bring it back to the shop and have them repair it.

Light came on after second time turning it on. I am taking it to the shop, but to help maybe figure it out I'm asking if anyone would know what would maybe cause engine light to pop on.

Great question!

OP - you need to check the code, otherwise it's a shot in the dark.

The code is the key. You didn't mention a CAI. If you did do a cold air kit I'd suspect a MAF sensor error, especially if you're not experiencing limp modes.

If you don't have a code reader (and anyone who works on their own car should have one), go to AutoZone or another parts place, and ask them to hook up and tell you what code(s) it is.

No dude , i had my CAI long before i got this round of mods, never threw a code out, MAF is fine. never had CAI issues for entire life of car or codes once i even installed it back in 2013.

Never had issues with car or mods i had on previously, until this round of mods i posted at the top of page, i come home and drive it the second time after the mods, and it threw the engine code, also i posted codes above.

Wow, that's a lot of codes.

Have the shop do it. Why would you waste 1 hp of energy yourself if you had a shop do the mods?

BTW: if you monkey with it, the shop may wash their hands of it.

Yeah i am taking it in tomorrow, like i said these guys are great at what they do, but idk what is going on. Just showed up the second day i drove it.


Update today when i started it, stabilitrak and engine light were on but went away, then as i drove to the shop to meet someone, there, engine light came on as i hit 100-110, was testing to see if something would make it come on, and it jerks when i let off throttle as well, so somethings not right. And as codes say, seems fuel related.

Definitely bring it back to the shop. They need to check the connections for the DSX Aux Fuel pump and possibly the FPCM.
