I have a Civic 98 LXI, i just recently changed my engine to d-16 and installed a SIMOTA air filter. Tinest drive ko siya and super ok and lakas humatak but the problem is sobrang low ng rpm pag naka ON yung aircon. We've adjusted the idle already para tumaas yung minor pero ganun paren. pag fresh start e umaabot ng 1800 yung rpm going down to 1000 but then when i turn the ac on e baba xa ng halos 200 to 100. should i try adjusting the idle ulet? or kailangan na palinis servo? or what else to check? can you help me guys.. newbie here.. tnx..
