My problem is that in the mornings when i start my civ, my car idles weird, stalls, backfires. I have to wait like 10mins so i can drive off with out it stalling, even afta that it backfires and clags, i hav to hav my foot on the gas or eles it will stall. but after 20mins or maybe even longer it runs fine the whole day, untill the nxt morning. When i changed sparks it runs fine for 2-3 days and then the prob comes back, i've done this a couple times and works but only for a few days then it starts claging again. I think my car is running rich, as i run out of petrol quickly 300km on a full tank. What could be the problem?

 

Time for some carb rebuilds . Also, check your fuel system. Sounds like it's running really rich to the point that it blows out the spark cause it to idle, weird stalling and bogging.

 

I have a dual carb D15B4 too!! Theres not many of us dude! keep it running strong.

I used to have similar probs with a dif car i had, and it ended up being the distributor, which was destorying the spark plugs and causing missfiring.
