97 civic idle problem
97 civic ex
d16y7/y8 minime
y8 auto trans
ive looked around and read alot about a Fast Idle Thermo Valve and ive also read a y8 doesnt have one.
ive changed my iacv and flushed all my coolant and put new coolant in but still once it warms up and its in park or neutral its idles up and down from 1000 to 2000 and back and forth. while in D4 not moving it stays at 1100. i have no idea whats left to check
