Own up, you fan out of fuel but wanted to style it out
Reverse hinged bonnets ftw
I wish!
I think a fuel injector stuck open, but it's hard to say. Nothing I tried made any difference until I rapped on all the injectors with the end of a socket extension, then it fired back up with a cloud of fuel smoke out of the exhaust and ran fine.
I've been meaning to replace the injectors for a long time. It was stumbling a few months ago and I ran some injector cleaner through which sorted it, but ever since then I've had a noisy injector.
Other possibilities are FPR, AFM, CPS, or the injector loom plug, but the FPR seems fine (I confirmed it doesn't have a bad diaphragm, couldn't do much else at the side of the road), AFM I lubricated the hinge on the flap just in case but the carbon track inside might be worn, I'll investigate if I need to... The CPS is a recent replacement (genuine Hella), not that that automatically absolves it. Injector loom plug is a common issue, it can trap water and/or be corroded, but mine seems to be in excellent condition. (It is possible that unplugging it and plugging it back in could have scratched through a tiny bit of corrosion or something though)
Fuel pump, fuel filter, and all ignition parts apart from the coil are new.
It was stuttering and cutting out like very bad fuel starvation or like some critical power or signal was cutting in and out, and I managed to limp it at 40-ish to a safe place at the side of the road.
It did that once before quite some time ago and I thought it was ignition related so I went through the ignition system, and it (likely coincidentally) went away for a while.
Additional things making me point a finger at the injectors are the fact that on a cold start the car has a bad jerkiness in deceleration until it has warmed up a little, it will occasionally fail to start and take a lot of cranking before sputtering to life (it has always done that, maybe 1 in every 20 starts) which might be caused by a leaky injector flooding it perhaps? And the oil has always smelled strongly of fuel when I service it.
