hi guys. i have 92 6g galant automatic which we overhauled last two weeks ago. the problem is when in park/neutral mode it idle normally at 900 rpm but when i am in drive mode and reverse the rpm goes down to 650 rpm and it goes down as i turn on the a/c.i've check all the hoses for vacuum leak and its all ok. i hope someone can help me what to check with my car. thank you and godbless.
