240 EFI boggs down then stalls

[2004 Utopia]

I have a 2004 Utopia 205 serial number OE418887 with a 240 EFI M2, it idles great but as soon as you give it gas it boggs down then stalls, but starts back up and idles again. I drained the gas tank, replaced the fuel pumps and filters, cleaned the VST, and replaced both temp sensors, any ideas?

I had the same issue when I bought my 2000 Challenger 240 EFI. I did quite a bit of it at the same time so I am not 100% sure which solved the issue but it's either the injectors that need replacement/servicing or the infamous TPS sensor.

I second the above advice. Sounds like a bad TPS as you throttle-up. Search here for how to test the TPS. I hope it is not your problem... as they are crazy expensive.
