Help me fix this so I can boost my poor Civic! UPDATE
Alright, I've posted about this before here, and about 3 times at honda-tech which was of course a waste of time. I only was informed of mispellings and advised to try ---- that I said I tried, because the idiots didn't read the thread.
Vehicle: Stock ass 1997 Civic EX with a D16Y8. ~160k miles Problem: While accelerating, even at constant throttle, the car seems to bog/misfire randomly through the rpm range. It *seems* to be worse when the car is warmed but I'm not 100% sure. Sometimes when the car is warm it'll start really sluggishly, turns over a few times, then kinda sputters to life. It has set off a CEL for random misfire in cylinders 1 & 2 a total of three times in the past year while starting the car. Eventually, the car starts jerking so bad during acceleration that others in the car notice it and I wouldn't be surprised if people outside can tell. When this occurs I can replace the plugs and it will somewhat remedy the problem for a short time. What I've Tried: New dizzy New dizzy cap/rotor New plugs (correctly gapped) New wires New igntion coil New fuel filter Injector cleaner Checked timing (was perfect, and yes I jumped the service connector and used a timing light) Only run Chevron gas Checked compression (got 180s across all cylinders, but I turned the engine over about 10 times before checking so maybe that messed up the readings) Checked TPS with multimeter, seemed fine. Like I said, the crap is completely random while I'm accelerating. It doesn't matter if I'm at WOT or partial throttle. Doesn't matter if the throttle is held constant or not. Seems to happen more when the engine is warm. I am pretty darn close to having all the parts needed for the turbo setup, but I'd like to fix this problem before I throw it on. The car also has a problem with oil...it disappears. I don't have black smoke, so I don't think it's burning oil but maybe the cat is just catching it, I don't know. I think it's leaking from the rear main seal because there seems to be oil drip marks near the tranny, but it doesn't leak when parked. Any suggestions would be great. UPDATE: Well I thought that the problem was solved when I replaced the dizzy. The next day when I was heading to work it did the bog/stutter thing... So anyways it's back to how it was. I have no ------- clue what the problem could be. Any other ideas? |

so you have a stock n/a motor? which motor.
|
Re: Help me fix this so I can boost my poor Civic!
A random cyl misfire could be anything in teh ignition system starting from
#1 cyl position sensor(Dizzy)normaly throws its own code roter(look for corosion under the roter) cap/roter u did(hopefully new) wires u did(hopefully new) plugs u did(again) then check your injectors use a noid light to check for correct pulse use a multi meter to check for correct resistance of the ingector between the two terminals |
Re: Help me fix this so I can boost my poor Civic!
Oh yeah, damn I always forget to l ist what motor, I'll edit the post.
I'll look more into testing the injectors. I have a set of DSM 450cc bluetops, a chipped p28 (borrowed for now), and willems chip burner. Just need a wiring harness and resistor box...will probably just wait until I can stick those in and try them. |
Re: Help me fix this so I can boost my poor Civic!
Have you listen to your distri. as the car is on? See if you hear grinding noise in the dist. Sometimes when the bearings are worn on the dizzy, the shaft will wobble causing misfires, codes, and even engine stalls. You should know what a normal hum from dist should sound like. If the dizzy is moving...you will hear the grind. Just my 2 cents.
|
Re: Help me fix this so I can boost my poor Civic!
Yeah I'll try and listen for something. I wish I knew someone with the same dizzy, everyone I know has different civics though... I'll try to locate one and try it.
|
Re: Help me fix this so I can boost my poor Civic!
hang on...........
u have 450's but now resistor box u might want to look into that if u want the car to run right |
Re: Help me fix this so I can boost my poor Civic!
I'm not dumb.
I haven't installed them, I just HAVE them. Like I said I have to get a resistor box and conversion harness before I can install them. I wish it was that simple...but the saga continues :6 |
Re: Help me fix this so I can boost my poor Civic!
i guess i have the same problem. i have a boosted d16y8. stock p28, stock injectors, fmu. its been boosted for about 6 months now. it ran like a champ, but only recently it started acting the way it does. the bog/ missfire.
|
Re: Help me fix this so I can boost my poor Civic!
try new injectors
|
Re: Help me fix this so I can boost my poor Civic!
Yeah, like I said I'll get the conversion harness and resistor box and try out these dsm injectors. If the problem doesn't disappear I'll try another dizzy. If the problem does disappear I'll force air into my engine at higher than atmospheric pressure.

Re: Help me fix this so I can boost my poor Civic!
resistorb box 25 shiped from canada

Re: Help me fix this so I can boost my poor Civic!
Hehe not trying to be a dick but someone already told me they'd send me one for $20. I suppose it doesn't matter right now anyway since I'm a broke bastard :P Just told my boss last night to shove the job up his ass and got a new job today that I start tomorrow, so hopefully I'll have money to spare soon. If that guy doesn't still have them I'll hit you up.
Thanks. |
Re: Help me fix this so I can boost my poor Civic!
I had the same problem after converting my d15b2 to obd1 I had a bunk dizzy the cyl 1 pos sensor was bad. My Gsr did the same thing but it was the ignitor. Hope this helps.

Re: Help me fix this so I can boost my poor Civic!
Yessir sure does, can I just replace the sensors or should I just go ahead and look for a new dizzy?

Re: Help me fix this so I can boost my poor Civic!
Well my friend has a new y8 dizzy...somewhere...that he converted to obd1. I guess I'll bug him to find it and wire it up and try it. If it doesn't fix the problem I'll buy the resistor box and set up the 450cc injectors. If that doesn't work...well I'll buy a new engine and then boost the one I have until it blows.

dude u aid u have chipped ecu?check fuel maps, ur friend prolly tuned to spec with HIS injectors not urs prolly goes lean |

Re: Help me fix this so I can boost my poor Civic!
Borrow a working dizzy from someone and try it. Its alot cheaper than buying ---- piece by piece at the local autoparts store.

Re: Help me fix this so I can boost my poor Civic!
Problem fixed :D
My roommate had an extra new y8 dizzy so I put all the parts in, had to put on a plug, runs great! Now just to get some money and pay bills so I can finish the turbo... |

I figured it was something with the ignition but wanted some second opinions before buying parts. |
Re: Help me fix this so I can boost my poor Civic! UPDATE
The POS is still having the same problem. I swear it's effin annoying driving a car that accelerates shaky and has unbalanced shitty tires...
Any other ideas? |
Re: Help me fix this so I can boost my poor Civic! UPDATE
another dizzy

Anyone?

Re: Help me fix this so I can boost my poor Civic! UPDATE
The same thing is happening with my y8. runs way rich almost all the time, altho sometimes it had its good moments. now it won't start. suggestions? i just picked up a new resistor box and a new fuel filter to try tomorrow

Could it be a bad fuel pump? People have told me that whenever their fuel pump went out, the car just wouldn't start. I'm pretty sure this is a fuel or ignition problem. |

When I floor it from a start, the car will get loud but is really really really weak until somewhere between 1-4k rpm, then it lunges forward.

Re: Help me fix this so I can boost my poor Civic! UPDATE
When I pulled my fuel filter today, theere was no presssure built up so i ordered a fuel pump
|
Re: Help me fix this so I can boost my poor Civic! UPDATE
Mine seems to fixed now. I just resoldered the main relay, put in a new pump, and new fuel filter. So maybe you oughtta start with the cheapest? I think it was the pump tho

Re: Help me fix this so I can boost my poor Civic! UPDATE
wow...still working on this? Don't replace the dizzy...I didn't mean replace it. Try to borrow someone elses dist. A minor defect in the sensors inside will not be fixed by a dizzy swap. I still think its the dist. But do what you must.

His symptoms and mine are identical except mine never pulled a CEL, and it just so happens both are y8s. I would buy an aftermarket fuel pump. If it doesnt fix it, ill be of value to you when ur car is boosted
