my 95' disco is running really rich. I mean REALLY rich. i just put in a new fuel pressure regulator, and fuel filter. i get white smoke out the exhaust when i first start. it runs really rough and idles rough. if i pinch fuel line before the fuel pressure regulator, it starts to idle okay and runs fine if i hold it with vice grips. whats making it run soo rich? | ||

White smoke generally means you're burning water. Black smoke would indicate a rich mixture. Blue smoke is, of course oil (which sometimes looks like white smoke). I'd give it a compression test to make sure you haven't blown a head gasket before you do anything else. Jim | ||

but what would cause the rich fuel pressure? | ||

I had the same problem and it was solved by cleaning the MAF and replacing some vacuum lines. | ||

Don't mean to confuse you or alarm you Gary, it's just that if you're getting a hi volume of white smoke then it sounds like you're burning water (coolant) - something seperate from your fuel problem. Running too rich will give you black smoke-not white smoke. I was suggesting a quick compression check to rule out the possibility of a head gasket problem. How much white exhaust are you getting? |
