1990 Jeep YJ Wrangler 2.5L Choking Down and Starting Problems

We have a 1990 Jeep Wrangler YJ, 2.5, Throttle Body, 5 speed. Sometime when we shift gears and accelerate it chokes down, like it isn't getting enough gas. We have tried cleaning the Throttle Body, the crankshaft speed sensor, changed fuel filter, cleaned air cleaner and ran sea foam through it. It still does it. Also, sometimes, when you start it, it dies then it starts really hard, lots of cranking, it is almost like it floods. Any suggestions? Thoughts?

Hi, mtjeep82! So, you're making headway, the symptoms have narrowed to stumbling between shifts and the start-up problem/return to idle quirk. Some thoughts... Your fuel pressure is actually slightly on the high side (normal is 14-15 PS), but this is unlikely to cause the symptoms you describe. You might readjust the pressure unless you suspect test gauge error...Given what you have done (plenty and good approaches!) and the remaining symptoms, I would adjust the Idle Speed Actuator Motor
