Hi guys i'm having some Issues wif my line.

First of all i was driving it along one day and it was fine. Then next time i drove and started it up

a lot of black smoke came out and it was running really rich and idle was was not very good. If you rev it would go

down instead of going up. It's not drivable as it would splutter and chugga chugga chugga Big Red Car... hehe..

Sounds like it's got really Lumpy Cams and is dropping out. I cleaned out the plugs and tested all my splitfire coilpacks and they are fine.

Not sure what it is though..

Mod list are

PowerFC

2530 .84 A/R Hi Flow spec Turbo

Stock AFM

Stock Injectors

Bosch 910 Pump

HKS EVC 5

Hmm that is all i can think of that it's important.

I don't understand it all as it was running perfectly and now it's...

If you have a d-jerto PFC then the afm wouldn't affect the idle like that, but if its not then yeah sounds like the afm, just give it a spray with some contact cleaner, and if that doesnt help then yeah ask another member to borrow theirs to help diagnose the problem, i wont mind you using mine just im not able to get back till wednesday, but give that a try to start with

i dont think powerfc has limb mode that prob why it stalled with the afm unplugged. just try borrow another rb25 afm. also did you put the filter back on when you cleaned out the afm. afm dont like it when there isnt a filter.

Ok Update... it seem to have gotten worse.. it's running on 2 cylinders now..

doesn't make sense how i'd lose 4 cylinders all of a sudden...

Goin 2 possibly check the loom for the Coilpacks.. if i do have to replace it?? how much do u reckon it will cost?

Gonna possibly tow it to the workshop that installed my new turbo 1 week ago so they can do further diagnostic...

Ok another Update.. Replaced all the Plugs and it's running on all 6 cylinders again..

still idling rough and lots of black smoke n running rich.. i guess it fouled the plugs pretty quickly running rich??

Goin 2 burrow off an AFM from a friend and see how that works..

Do u guys know th resistance value readings of the AFM on it's 3 pins?

I'm gonna use a Multimeter and check the readings..

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
