Default Rough Idle,

My 2004 with a 4.0 started acting up when i started it up, rough idle with black smoke coming out and could not get any power when i was trying to go up a small hill,press on the gas and the motor lost power. Let it idle and when i pushed on the gas the rpms would go to 3000 and back down slowly and almost die the go up to around 750-1000 rpms. Any help would be nice.

Thanks
Rodknock

Default Re: Rough Idle,

Sounds like you're running pig rich. Check your MAF and see if it needs to be cleaned, that might be it but I'm just taking a guess based on what you said.
