Good day to everyone I'm from the Manila,Philippines I am hoping someone can help me in my problem. I have a '93 lancer with 4g15 engine non-turbo, the problem is when i turn on the a/c the idle stars to drop at apprx.700rpm so i had an IAC and TB cleaning done DIY using carb cleaner. After the cleaning i warmed up the car then idle fluctuates at 1500rpm-3000rpm and from 2000rpm-3000rpm when a/c is on when depressing the pedal. I think my iac is working properly because before i assembled the gear kit inside the iac i set it in open position meaning air can pass through, after i ran the engine and opened it again for inspection the gear is now in closed position meaning the iac motor is running.
Can somebody please help me on my problem, it was not fluctuating before i cleaned it. Thank You in advance.
and sorry for my English !!
