My 1.8 Ljet left me stranded yesterday. I did the usual debug stuff. Turns out the ECU is overfueling the engine. Injector pulsewidths are 10ms to 15ms under cranking conditions. This is roughly 10x what I would expect at startup. Anybody have any suggestions for what might be causing this problem? The airflow sensor maybe?
Thanks for any suggestions you can offer. -dave sprinkle |

That's not all that uncommon on Vanagons, BMWs, and Volvos, but it's the first 914 I've heard of with that failure. Glad to hear you found it! The Cap'n

Yeah, thanks for the support, Cap'n. Wanna sell me a new reg? Cause I don't think I'm gonna trust the spare one I've got in my old parts bin.
