i got that lope idle setting on my truck and when i turn it on there is white smoke coming from the passenger side back of the engine. I just replaced the injectors and put new injector o-rings in. And thats why i'm hoping its not the injector o-rings and was wondering if its the o-rings would u see the smoke coming out of the vavle cover because its not coming from the vavle cover and was hoping its the up pipes because i'm planning on getting new ones. Smoke is coming from the front passenger side (closet 2 the cab.) A little blue smoke when it starts up in a cold morning but goes away after a little bit.
