Hey Gang,
I just replaced all the fuel injectors in my TWI Beetle. Before replacement, the engine had very little power, was smoky, and stalled out easy--but, the engine ran very smooth. It felt like the engine just needed more fuel, because a slight push on the pedal and a to-the-medal push accomplished the same amount of acceleration. Anyway, once I replaced the injectors, I had to leave on a month-long trip before I got the engine up and running again, so it sat with all the parts back in their place, but without any action for a month.
Since the replacement, I just got the engine running. The engine sounds much louder, but the whole engine is having a big cyclical shudder (misfire I'm guessing), which it never had before the change. That said, the engine runs smoothly and doesn't die--I left it running in that state about 2 minutes before shutting back off, afraid I might do damage.
You can see the engine shake here (https://www.youtube.com/watch?v=1c3Tbfth0p4). After turning the engine off, a ton of bubbles and gurgling came from the IP, so I'm guessing it was purging air (https://www.youtube.com/watch?v=ng_gxbC9o9g). I cracked the injector nuts and got fuel spraying everywhere, so I know fuel is making it to each injector.
What's my first move to try and get the engine running smooth and even?
