Stumbling and hesitation is gone.its wierd twice now iv started it up the rpms drop down and car stalls. Starts up again right after.i was checking for vacuum leaks again and therea no vacuum at all going thru the egr valve vacuum.isnt there supposed to be a constant vacuum there?

RatherDashing · 04-07-2013, 05:21 AM

milage has seem to improved. horrible vacuum leak im still trying to locate. up and down constant rpms at 1-1.5

so I unplugged the egr valve today and no cel came on. I unplugged plug going to the box that goes to the cvc valve and egr control solenoid valve and still no check engine light or noticeable engine difference.

where should I go to next?

car has been running absolutely beautifully lately. I have an ill feeling this is it!!!!!
much help wud be appreciated on this one

You can't hear a whistle or sucking noise? Spray carb cleaner on all vac lines or inspect and replace vac lines are cheap. It shouldn't idle at 1500 unless it's a very cold start.

it idles at 1500 at cold start. still acting like theres a vacuum leak.
seems to stop idling high and lowers once my car stops. im thinking maybe a leak in the intake manifold sumwhere i cant find

basically my plans with this car changed all around last night. i do want to get it running and getting its milage up. save up and swap in a d16z6 engine and rebuild the d15z1 thats in there now and swap it into a different civic someday. and this could be going underway within the next 3 or 4 months

Mine idles high when cold. Only at a stop and warm does it idle at 500. Thats a plan. But if it runs i ld leave it alone.

The milage is still atrociously bad.feels like items getting worse and worse

Jack it up and make sure you don't have a dragging break.

RatherDashing · 04-18-2013, 12:34 PM

iv never thought of that. def will check it out tho. once I get money figured out figure out if its the egr or not. I cant hear any vacuum leaks. but it doesn't seem like anything after the egr solenoid is recognizable. no vacuums or electrical. unplug things and cant find a vacuum or change in car running. I thought that if u unplug the egr valve the car starts idling really weird and cel comes on
