97 Legacy gt hesitation

[swilde20]

I just bought a 97 Legacy gt that the guy was in way over his head and now i'm thinking i might be also. He put in a JDM motor and drove the car about 10.000 miles and developed a hesitation, when a idle the engine runs perfect. When you try to speed up you get a hesitation and a little bit of a chuging, but at certain rpms it does smooth out and run good. I have a flashing check engine light and the code comes up p1101 Manufacture control fuel and air meter. also have 2 other codes po500 speed sensor a and po325 knock sensor 1 bank 1. Anyone have any ideas.

 

Thanks Steve

No ideas, common even an educated guess would be ok.

Check plugs and wires for the hesitation.

No one else has any ideas?

P0325 -Knock Sensor Circuit Malfunction

 

the hesitation could be the knock sensor. mine was old and tired and caused hesitaion under slight load, driving uphill. if i punched it it would eventually catch and go. mine did this for a while before it threw a code.

 

P0325 is actually a circuit problem that could be a connector or corrosion under the sensor, maybe. but depending on the miles, it may be due anyway.

any speedo issues? does the AWD work properly?

if it is an auto trans, put the FWD fuse in and take a test drive. see if you can feel a difference. i usually can.

i have no idea about the last one? but it too sounds like a circuit issue?
