Car is running like a dog!

[LRRH]

Sooo last weekend we installed a cobb AP after the new intercooler, hpfp internals & spark plugs where installed. Found the closest possible stage2 map to mate with my mods and its now running like a dog...hoping to receive some guidance. I've not performed a WOT log as yet but this is the map I'm using and the error codes :-/ and please, no flaming as I'm still very green with all this and I'm just trying to understand why the car is acting up suddenly

Stage2 + SF + TIH + IC 98 v232


Error codes
PO138
PO172
PO234
PO300


I'm beginning to think I should've left the haltech on lol


Anyways any help will be gratefully received

Interested to learn here. Have you read what those codes are?
When you say as close as possible, what mods dont match your chosen map or vice versa?

Hey Alex, well the mods listed as you can see are pretty generic & i have all of them, besides SF which from what I can tell is the Cobb intake. I have an injen intake.

[SarcasticOne]

P0138 - HO2S Circuit High Voltage Bank 1 Sensor 2
P0172 - Fuel Trim System Rich Bank 1
P0234 - Turbocharger Engine Overboost
P0300 - Random/Multiple Cylinder Misfire Detected

what else changed whilst you swapped over to cobb AP?

[LRRH]

Spark plugs went in, fuel pump internals upgraded and a couple of weeks before I installed the corksport tmic :-/ those error codes sound bad

have car at idle, fuel pressure should be ~400-450
my bet is that either a spark plug isnt igniting properly, or there isnt required fuel pressure

[LRRH]

Says di fuel pressure volt @1.6 :-/ on idle

Codes are as follows (from the L3 section of the Mazdaspeed 3 2010 manual):

P0138 - H02S circuit high input (Heated Oxygen Sensor)
P0172 - Fuel trim system too rich
P0234 - Turbo/supercharger overboost condition
P0300 - Random misfire detected

Which intake are you running? I think you may have the wrong map for your intake loaded

Did everything go in at once or the ap later?

Not the volts, there should be a di fuel pressure monitor.
Maybe take a log at idle?

should be an option that says: HPFP Act. Press. (PSI)

[LRRH]

Fuel pressure sitting around 450 - 460, everything was installed then the cobb loaded. I have an injen Sri

Try flashing to stock then back again? I had a weird issue with the hypertech once.

Have you tried reloading the map? strange to get all of them I think. You have not driven it yet have you, just been idling on the spot?

[Yeldarb]

Sounds pretty suss dude. Try like they've stated, then move through stage 1 then stage 2.

Did the codes pop up as soon as you started? Or a few days later?

You said earlier that it was a lot stronger bit very rich.

yeah, been driving it daily since the cobb was loaded and it seems to have gotten worse as the week has progressed...not putting around the streets mainly when i'm on the motorway climbing through the gears

hey mate, yeah the car felt pretty solid earlier on...biggest change I noticed straight away though was the extra carbon build-up on the exhaust....but bucket loads of black smoke as well....codes came on today...

Could be a fouled plug.. Maybe give a stage 0 map a try too.
