tps??

ok i've got a 90 dx hatch 1.5l
for a while now its been surging at idle drives fine just surges on idle

it can't be a serious problem cuzx i still get 38mpg

i've changed the main relay, cap/rotor, O2 sensor no change

just wondering if this could be the TPS sensor on the TB cuz its a hassle to replace (whole Throttle Body)

if you can help me out that'd be great thanks!!

The Idle Air Control Valve is usually the culprit when the idle is fluctuating. Its on the back of the intake manifold.

def check the idle air, see if the nut can be adjusted. then replace the TPS sensor.
