85jeep cj7

what I have is an lq4 out of a 2005 sierra that I have put into my cj7 engine seems to run good at idle, and will take fuel fine in park. When you put it in drive and take off it acts like the exhaust pipes are clamped shut at full throtle, when you let off the throtle slowly it will open up and run when not putting the motor under load. any help is great thanks in advance

How long have they been installed and what kind of air filter are you using?

Are you sure the PCM is tuned properly so it doesn't think its in Park all the time?

Definitely get your tune looked at!! One wrong mistake in the tube can make a project a pain in the ***!!
