Finally something different in my Suzuki Cara's odd engine behavior. DOHC F6A engine troubleshooting

Testing my Suzuki Cara/Autozam AZ-1 by letting it have some zoomies around the neighborhood to terrorize everybody.
Finally seem to be getting somewhere with this madness. It finally acted up a little different. This leads me closer to determining the issue is with my fuel system somehow (plus the injectors and regulators are something I haven't gotten to touch yet amongst everything that has been replaced)
I ran some fuel system injector cleaner and tried to drive the car around.
Going over some viewer suggestions (jiggling loose connections, fuel pressure regulator vacuum, valve float?, I don't know man...) thanks for the suggestions!

The brrrrrrr instantly made me think missfire, now this could be a lot of things (think what makes the spark not transfers it, ie pickup, module and or coil) but from seeing the video with you changing fuel pump and seeing the sh*t in the tank, pulling the injectors and getting them cleaned and flowed wouldn't be a bad suggestion regardless.

@AnythingWheeled Месяц назад

Yea I just pulled the injectors and stuff out and sent it off I think I may have figured it out. Waiting to get my stuff back to confirm

dont lie, you dropped the camera so we didnt see you driving without your seatbelt! ;)

@AnythingWheeled Месяц назад

Seatbelts... Stop signs... Speed limits... What's that?

maybe ignition misfire/cut due to bad cam sensor in distributor? these engines dont have a crank sensor, they only have a cam sensor/ignition pickup in the distributor, maybe there is an issue with it that presents differently when it gets warm or based on vibrations. cracks in circuitry can do this as it will make contact and work until a certain frequency or if it gets to a certain temp then the circuit will open and the connection is lost. could be in the pickup itself not just the wiring. you could try scoping the wire for the cam sensor/ distributor pickup and see if it brakes down at rpm cut. also ignition coil may cause this issue, try scoping the coil circuit and see what happens when it cuts,

I was supposed to do the tooth counter thing with the tunerstudio logging but I took some stuff apart and can't do it yet. I may have found it but need to get the parts back before I try and confirm..

Take your air filter out and see if it acts differently? Reasoning- if it gets better, it's an air problem. If it gets worse, it's a fuel problem.

@AnythingWheeled Месяц назад

I ran it straight from the throttle body to atmosphere, it ran worse

@evilthorne Месяц назад

I take it you checked the gap and everything with plugs and ignition? Boost can blow a weak spark out.

@AnythingWheeled Месяц назад

This is probably 3 or 4 videos in of me throwing parts at the car going through everything that possibly could have been wrong from the easier to harder things. I think I'm on to something, confirming on the next video of these shenanigans

@spencerboucher21 Месяц назад

Have you checked the resistance of the fuel pump wiring?

@AnythingWheeled Месяц назад

I have not, I can probably do that real quick

@frigglebiscuit7484 Месяц назад

not valve float, valve float sounds like a god awful spitting and popping. it doesnt sound like ignition breakup either, runs to smooth, even when it hits the wall. im gonna guess loss of fuel pressure or injector firing.

@AnythingWheeled Месяц назад

I also understand that valve float doesn't move around by swapping ECUs that have different tunes, Correct?
