so i've had this weird issue for a month or so

car runs fine, even at 70 with low to mid throttle no issues

but when i floor it, it stumbles and doesn't have the pull it should have

so, i replaced the fuel filter, cap , rotor, plugs, wires, timing belt, adjusted valves, ignition timing is spot on

all of this actually made it worse

soooooo, my guess is the more complete burn due to tune up is making it want fuel even more?

can a fuel pump work fine with little demand but not work the way it should upon high demand?

burned valves? clogged cat? egr? o2 sensor?

i have no cel, but i'm assuming it works properly

i dunno, i'm stumped but it's a pia and was hoping someone else has been down this road

main relay is also only a couple years old

91 civic dx

212k

 

Is the LED on the ECU blinking any codes?

 

it is under the passenger foot carpet? and i need key in 2 position?

i also dumped in some chevron techron thinking maybe it is dirty injectors, nothing

 

well, all i see under passenger dash is the air box and fan

 

 

yep, found it

it blinks 15 times, then 16 times and repeats

 

Reset the ECU and then drive the car to see whether one, both, or none of the codes repeats.

 

i'll disconnect pos on batt and leave it overnight, was thinking of doing this anyhow, i'll report tomm, ty

 

Just pull the Hazards fuse for 10 minutes.

 

Sounds very distributor failure-ish.

 

great

 

well ,just took it out

same problem, but i have no flashing led

replace dist?

 

I'd drive it a bit more to see whether a code is thrown.

 

ok

i think i'm gonna replace dizzy anyhow, the cardone is only $130

and being the coil and igniter comes with it, i could eliminate a few possibilities

it does have 212k on it

is there a seal behind it like the cam seal on other side? all i see is an o ring on majestic dist blow up

there is alot of oil leakage from behind the diz

well, enough to coat the tranny underneath

 

There's an O-ring and an internal seal. Is there oil inside the distributor?

 

not that i noticed when i changed cap, but i didn't shine a light in the crevices either

so there is no other seal other than the o ring that comes on the diz?

 

Remove the inner cover and look inside the distributor for oil.

 

There is an o-ring on the shaft. Sounds like your ignitor might be failing.

 

no oil in diz, was a bunch on the sensor under it that's in the head

 

That's an O-ring issue.

 

yep, so may as well kill that problem in the process

how do i know if it's a td-01U or td-18U?

the one i have now says tec on the top of it, the coil i beilieve

 

well majestic only says td-01U for the 3dr dx, so i'm going with that

what is the td-18U? in the crx , si or something?

 

bueller?

anyhow, this dist should only fit in one way so there is no reason to have motor at tdc , correct?

also, in the event this doesn't work i was looking at the fi system, there is a primary and auxiliary injector

is the purpose of the aux injector to provide more fuel when the demand increases?

 

well, got on it on way home from work

and it's no longer doing it....lol

it did it sat morning after reconnect

does it take the ecu a day to work out the kinks or something?

just as well, oil seal was leaking and i need this car to last 3 yrs, so at least i'll have a new ignitor etc

 

or should i create a new thread?
