Is there anyone who would be willing to help me personaly with the problem with my swap. I live in Washington state in Arlington? Pls, I need to get this thing running right!!!!!!

****PROBLEM****

Car runs perfect when cold, but as soon as it gets to normal operating temp, it starts bogging and hesitating like crazy. There is only 1 sweet spot on the throttle where it won't do it........pls help, I am desperate. I have tried switching the 2 o2 sensors and it didn't help. No codes! I got the motor from HMotorsonline complete with the Hasport sub-harness, mounts, and linkage. I have checked the voltage on the tps and it is fine. Everything that is supposed to be hooked up is.........

 

guarantee its the ground for the throttle position sensor or the sensor itself

 

where is this ground located at?

 

Definately something with your tps. Change the sensor before you do anything else. Hondas are famous for surging when the tps goes bad.

 

What model is your car, if it is a dx or std did you switch the wires on the tps, it is commonly overlooked when doing a swap. Good luck

 

same problem here....let me know if you find anything out

 

The car is an Si. So I didn't have to change the tps wireing. Changed the TPS with a known good one and the problem persists. Can someone pls help, I am desperate here. I don't want to drive the soccer mom car anymore
