yeah! definitely could've been more explanatory in my first post sorry about that. plugs look good, cleaned maf was the first thing i did, and have not found or heard any boost leaks. stumble also may not be the best word as a descriptor either...it's more like im cruising along at say...

Within the last 2-3 months I have noticed an intermittent stumble while driving that seems to be getting worse, and I think accompanied by a sulfury smell from my exhaust.... Check out the logs I've posted, I think my AFR is f**ked and that is throwing everything else out of whack because I...

took a new log this morning during the drive to school and logged everything you said to @Enki also @Raider here is a screenshot of when i pulled codes after I got home the EGR is from the EGR delete I did so that mystery is solved hahaha

@Raider weird, this is the screenshot from bluedriver that I pulled the other day. I'll run the codes again from versatuner in just a bit and post those again. I cleaned the maf and the air filter yesterday and checked the maf harness, everything looks okay,

@Enki okay awesome. did you look at the other log labeled "startup and idle w few blips at end"? you can see there that fuel rail pressure is high immediately after startup until RPM stabilizes around 30 seconds in, and then fuel rail pressure falls until it stabilizes again around 400psi...

@Awafrican cool thank you for chiming in. I'll check the HPFP ground first thing when I get home. the injectors were not ultrasonic cleaned when i rebuilt the engine, but i did do all new seals upper and lower, also btw p2188 is for system too rich at idle, not too lean. or were you referring...

@Raider any possible help here? here are some logs, in xlsx and .csv, the excel are a lot prettier and easier to navigate also here is a picture of the spark plug out of cylinder 2 did a compression test and came back with cylinder 1 - 168 psi cylinder 2 - 142 psi (160psi after I put a...

Year/Make/Model: 2009 Mazda Mazdaspeed 3 Mileage: 196582 Location: Tucson, AZ DTC's: P2188 and P0302 Modifications: Cobb intake, EGR delete, balance shaft delete. rebuilt engine myself, now has about 10k miles on it. all machine work was NOT done by me. bored out .5mm over, same internals except...

This is perfect! Thank you so much. Any idea on the actual sizes of the bolts? I'm fairly certain I am missing one or two, so I would love to pick up a few more before I tear it apart.

Does anyone have a diagram for the bolts how the tranny bolts up to the block? I am going to be doing a rear main in the next couple days and I want to make sure I buy a new set of these bolts because when I did it last time I kinda just put stuff where it fit, but I would like all of the...

It was an aftermarket version of the OEM mount. I replaced it with a JBR Racing passenger mount and it is *super* rumbly and vibratey now hahaha. Got a few hundred miles on this JBR mount now, gonna check on it again sometime this week to make sure it is still installed properly, but I...

This one was solved with a bad passenger side engine mount! It only had a few hundred miles on it at this point, but the rubber had completely deteriorated causing some metal on metal grinding.

Hearing this...grinding noise? Weird kinda rumbly/shaky noise when the engine is under load. Can be from start, or even at 40mph in 4th or 5th gear. Does anyone recognize this sound before I start pulling shit apart or assuming the worst? Ignore the shaky sunglasses in the beginning, you'll...

Hahaha yeah its the valve cover to intake recirculation tube. Gonna take it for a couple mile test drive right now and see how it feels, hopefully that CEL stays off and the rich/lean stuff sorts itself out.

Well I figured again I would try to bring some closure to this thread. And I wanted to thank you all for dealing with me, a genuinely stupid, stupid idiot. Would anyone care to place a wager on why my fuel trims were so weird? I ordered a new MAF sensor and I was going to install it just a...
