I have a 1989 740....when my dad had it the idle seemed to high, but when I got it he turned the idle down...now the car is so low until it turns off.....so me being mr. Fix it I tried to increase the accelerator or increase the idle and I ended up messing up the connection to the gas pedal...it's t...

@Vjaneczko.....So basically redo the engine!!!! LOL!!!! Just kidding, but that sounds about right as well....I might just have to put my car out of commission until I get this fixed. How long did you ride around with this issue? I have been driving around like this for 1.5 years and my car hasn't br...

Tru....my dad is a mechanic and all he buys is volvos....I'd rather fix it....so is that where the click click noise coming from as well? That is the most annoying.

J_cd....it's a nonturbo....Jason Dunn....Is this a guess or are you sure? To all it's frustrating because I don't know what it is...and even my dad as being a mechanic doesn't know what it is....The car runs fine...I notice at time the exhaust gets really smokey (white smoke) and the noise comes and...
