1991 Accord with about 225,0000 miles on it. Was wondering if anyone had any insight as to why my car idles roughly in park and neutral. Replaced the high pressure value. Recently rebuilt the engine, runs great. Let me know if anyone can help me out.

 

i had the same prob its your idle air control valve is your car ato. or standerd

 

last time i checked standerds dont have park

 

Yeah it's an automatic.
