I have a 93 lude with an h23a1. i swapped to the a3 put all my parts and sensors on it... now that i got it in when i go to run threw the gears it wants to jump a lil bit threw the rpms with my stock ecu... i put my buddies chipped p28 in and it didnt jump anymore bt it is like half throttle and bogging out... anyome have this problem with this in their lude when they did the swap... all sensors and parts from a1 bolted up... ive heard it could be dizzy or the knock sensor or fan temp sensor any help would be great... its not my clutch slipping i put brand new complete clutch kit in

 

What does jump a lil mean exactly ?

 

It hesitates and sputters my timing is perfect.. i just did it again tonight to make sure...

 

new dorman tps (f u blox!) helped me with this, i still get a little hesitation once in awhile, it's mysterious....

Maybe your egr system is clogged. When I got my lude with a h23a3, the ports were already welded. Doesn't hesitate the slightest; pretty smooth for an older engine with unknown mileage.
