Distributor perhaps?

**shepherd79** · 06-18-2004, 07:37 PM

first check your ECU for codes. here is how to check your ECU https://www.3geez.com/showthread.php?t=26342
second, while the car running (idling) pull the vacuum lines of the distributor.
the idle should change to worse. if you plug them back it will come back to normal idle.
third, remove distributor cap, and check for red dust or burn out contacts.
if everything checks out just fine.
try to clean TB (throttle body) with some carburator cleaner.

**bboipinoy112** · 06-18-2004, 10:48 PM

ok. i will check the things you guys have said. get back to you tomorrow.
Any other Ideas?

**86LXItooFAST4me** · 06-19-2004, 04:53 AM

what happens when the fuel regulator goes out? or do fuel regulators go bad?

**cruznz** · 06-20-2004, 04:05 AM

check for fault codes as Alex has suggested...did this problem begin after you did the tune-up?.....it may be possible you could have disturbed a connector, vacuum hose or wiring for TPS, MAP, ECT....

***carotman*** · 06-28-2004, 10:23 PM

Mine did that when my O2 sensor was screwed up. check the voltage on the O2 sensor... there is a testing procedure in the Repair manual available on www.pauldesign.ru

**contraband** · 06-29-2004, 09:35 PM

Does it give a check engine light? If so it is in limp-mode. Otherwise as was mentioned it is possible that a sensor may have been disconnected. A friend of mine blew the vacuum line off his MAP sensor (at 18psi, heh) and it did almost exactly what you are describing.

**Kevin** · 07-01-2004, 07:04 PM

My does that also. There is no engine code and the cap and roter are fine. I have also already cleaned intake. I think its the vacumn advance but why?? At an idle while flipping it is fine. When i get off the gas its like it pops though the exhaust. HELP!!!

**accordlxi2.0** · 07-01-2004, 07:10 PM

i had that problem too, when i had gotten both my lx-i and lx.
the lx-i whould have the check engine, after a few minute's, and all i did was spark plugs and dizzy cap and rotor. . . . . .

**Kevin** · 07-01-2004, 07:12 PM

all i did was my plugs last week!! I wish it would throw a code!! Than i could figure out what it is!!

**accordlxi2.0** · 07-01-2004, 07:15 PM

and it still pop's hmmm, have you tried advancing the timing, if the timing to retarded it's gonna lag like that . . . . . . .

**Kevin** · 07-01-2004, 07:19 PM

Ya put fully retard and than full advanced!! It was better when advanced!! I dont know what the deal is. If the advance thingy was leaking would it do that?? Like i will drop it into 3rd and full it and ill hold it till the top end of 4th. Than makes noises and jumps when i back off!!! Maybe it loves to go fast!!!

**accordlxi2.0** · 07-01-2004, 07:25 PM

hmm it may idle uneasily, if you have to advance it so much then something's wrong.
try this . . . . .
with the engine fully warmed. . . . .
and advance the timing.
dissconnect line two, cover the vac port so the engine won't shut off, listen and see if the rpm's dropped a lil'
then connect it back to see if it raised back up.
and try the other line, it play's some what a part too. . . . . hopefully this'll help.

ohhh when you push the gas and it kick's in that's the secondaries opening . .it's like a supercharger.

**********3 GEEZ 4 LIFE**********

**Kevin** · 07-01-2004, 07:36 PM

Ya the idle does change when i do that!! Than goes normal when reconnect them. Why would the engine shut off?? Mine just ran. It sounded a little ronchy because the vac lines are off but it still ran!!

**accordlxi2.0** · 07-01-2004, 07:41 PM

ohh well that;s happened to me sometime's, but you should do it one at a time.

wait back up here what do you mean when you wrote:

like i will drop it into 3rd and full it and i'll hold ittill the top end of forth.
than make's noise and jumps when i back off. umm i'm kinda tired so the honda memory is kinda slow LOL . . .

what kinda noise????

**Kevin** · 07-01-2004, 07:45 PM

pops and sputters and jumps!!!

**accordlxi2.0** · 07-01-2004, 07:52 PM

is it auto or stick . . . .
so you have it in 3rd and you floor it, and once the tach reaches 4,000rpm's, you then shift it into 4th gear and it does that or vice-versa. . . . .

**Kevin** · 07-01-2004, 08:23 PM

It is stick- ill be driving in 5th gear and it will be acting up and i drop into 3rd and shift at like 6500 and run through 4th gear!! It doesnt effect accerleration at WOT!! It just lags and pops cruising and regular driving!!!

**accordlxi2.0** · 07-02-2004, 11:20 AM

hmmm and you gave it a full tune up? . . . . .
let me ask ya what yo have listed at the bottom are your mod's right????

**34748lxi** · 07-02-2004, 05:58 PM

Greetings fellow 3g owners. I am just a noob here but here is an interesting story that may help. I just bought an 86 a couple of weeks ago and it has (had) a similar problem. It would have this wot lag up until 3500 and just take off after that. I discovered the timing belt was fairly new and at first just assumed that it was installed correctly. I was wrong. When I lined up tdc on the flywheel I could see with the valve cover off the cam gear was way too advanced. But when I went to loosen the timing belt and line up all the marks, all the power was before 3500 and diminished after that. I then retarded the cam by 1 tooth and boom it runs great all the way thru redline. I still have the original cap, rotor and wires from 1986 (120k) and it will still bark 2nd! It's an auto too!

**accordlxi2.0** · 07-02-2004, 07:15 PM

that's good . . . . . .
what ya got dx, lx, lx-i

**34748lxi** · 07-02-2004, 07:48 PM

lxi, of course I will replace those long overdue parts. Pretty decent condition for it's age. Don't care for automatic but maybe that will change one day. Don't really want to mod it out too much(except for those original 13 inch alloys, they gotta go!)I just want to get all the little problems worked out, get something to replace that original Honda radio, window tint, cai, and some new paint. I'll be happy with that. Sorry, I won't go on and on here, might be in wrong thread.

Yea it's funny that my car just doing this last night for some reason. Go to subway to eat and 10mins later it runs like shit. No codes, runs got at WOT but regular it pops and once you let off the gas it falls on it's face. I'm totally lost. Haven't had time to fully check everything but from what I know it act's like it's the MAP sensor. How it's works good at WOT but at low air flows it's shit.

**Kevin** · 07-03-2004, 09:08 PM

CHeck your vacumn diafram!! Mine had the same problem. There is a rubber O ring that borders the distributor and the vacumn advance. On mine the o ring was all distorted and my casue casueing it to leak vacumn!!! Good luck!!!

No i do not have N20 any more!! I had a 50 shot on the car for like 5 mos!! It all some series ass with that N20!!
