Hello, I have a 98 Acura CL 2.3L that I just swapped a JDM F23 into from the original USDM F23A1 motor. I'm having a few different issues I would like to tackle after getting the swap completed.

Number one issue is the vehicle wants to die after I give it some gas, wether it be a couple hundred rpm or 2000. Whenever I go to let off when it's parked the engine will fall to a staggering 350 rpm and idle back to about 850 give or take 50. I have cleaned all my sensors, got new gaskets for the valve cover, exhaust and intake. I cleaned the intake and throttle body completely before install. The intake was swapped onto the jdm from my USDM as well.
I would like to hear some advanced advice on what may be causing such a issue.

Second problem to discuss is a small coolant leak coming from the back of the engine running through the rear engine mount and past the driver side cv axle and on to my sub frame connector. The leak isn't coming from the heater core hose by the way.

So, are these two issues connected? Thank you for any feedback.

Tldr; when I give the car throttle it wants to die after I let off the gas. Strange coolant leak from the rear mount.Help

This is the tuning section, not tech. I'm most certain your CL doesn't have any type of engine management system besides the stock ECU

No advice other than complaints?

Neither of the above posts were complaints.

Do you know if the engine was working properly before installing? Trying to determine if this is engine or install related.

Possibly issues, bad spark, faulty sensor ect.

Need more info.
