Apex engine swap and now won’t run right

[mikextx]

I would try to locate a dead cylinder, maybe use an infered thermometer. Like MrSled said, it sounds like its missing bad

It’s got the Gems controller o it and is grounded good . However the engine runs the same with Controller Un plugged also

I’ve checked all plugs and none were wet but I do agree it sounds to me like it’s onky running on 3 cylinders
I can’t keep it running long enough to heat up the cylinders

BTW your pressure sensor should be referenced to intake pressure somehow.

Well we’ve got her figured out
The entire time it was a miss adjusted throttle cable . It was not adjusted to sit on the throttle stop so it was throwing the sensor and everything out of wack . We got her adjusted and she runs like a monster ! My son got to make a couple test hits on the grass and says it’s a handful!
Thank yiu to everyone that helped and gave us advice ! What a great forum!
