motor was installed everythinhg runs fine, but it bogs at really low rpms when i shift into gears, i'll press the gas peddle and it bogs and shakes, like its not getting gas but as soon as it to about 1700-2000 rpm it runs fine, buts its only while i'm driving, it idles perfect and revs at idle perfect. any help is appreciated, thnx, Btw current set up is just a swapped d15b for my old d16z6 staright across swap.thnx

 

bump... hope everything works out

 

Did you inspect or replace the common wear items (plugs,cap,rotor,plug wires,pcv valve) before running the D15B, and have you checked the base timing?

 

everything was off my old running d16z6, so i would assume it should be fine, timing is right on, i know that for a fact, also it only does this problem when the car warms up , when its cold its fine, just due to the fact the idle is high

 

I recommend a compression test.

 

allready been done, guess it was good i had it installed byt the japanese used engine supply i bought it from, guess it time to take my warranty

What were the #s?

 

i think your head gasket is toast... yeah, we need the comp. #'s

 

don't know the numbers but thier warranty is pretty much the same as HMO's so i'm covered, hell i've only had the car for 6 hours, i know its not the headgasket. i double checked that

 

try changing your spark plug wires and see if the problem goes away

 

if that engine has been over heated in the past it may have warped the head gasket which could cause bad compression and make it bog at idle... but if its under warranty let the shop fool with it

 

i'll try the spark plug wires, also if it would have been overheated in the past i beleive the heating tabs would be melted, right?, pretty sure they weren't. also it only bogs while driving , i could be at a stand still idle and rev it up just fine. it only happens while driving, like the fuel is cutting off. but i'm calling the shop today.

 

checked spark plug wires they are fine, along with the dizzy, ^^ for anymore suggestions

 

my civic had a miss fire, turned out to be a crapy dizzy cap and rotor (thanx NAPA)... it was arcing between the rotor post and cap contact...
