Okay, some might remember me helping my dad out with the Honda and trying to figure out why it was sputtering. Charging the battery for like 5-6 hours ended up solving the problem so we thought it was just a weak dead battery. Well, now it's doing it again but much worse and idk if this video mimics really what i can feel and hear. But it's almost like it's MISSING really bad. When i rev it, i rumbles some and misses.

Here's the Video

Car Info:
1993 Eg sedan(I believe the ex model, correct me if i'm wrong lol)
d16y7 around 120k miles give or take
300k miles on the body
New radiator
New ThermoStat
Did a full Radiatorflush, new oils ect
Degreased the WHOLE engine bay and dirty parts to get better air flow and less hazardous


Not sure what OBD it is
I believe it's pretty ready for a tune-up
Havent checked the plug's will do
What would be running rich?

Sorry man, but what is the info on the car again? Is it OBD-II? Is the CEL light on?

What is the condition of the engine? Recent Tuneup? Good Plugs? Good Filters? Is the base Ignition timing within specifications?

If you idle the engine and pull off on spark plug wire at a time, does anything change?

Has it been running rich lately?

how long has it been since its had a tune up? plugs, wires, cap, rotor, etc

If you had to charge the battery to get the car to run right and now it's doing it again. My assumption is that the alternator is bad. Is your battery light on?

Not sure, we got it from an old Mexican guy that didn't really ANYTHING about the car

So far since we have had it i have changed:
New raditor
New oils/liquids
New thermostat
New Distributor cap
New rotor cap

Both me and my cousin said to my dad i think it's time for a tune-up, don't know how long it has been since but knowing how ignorant my dad is he want's to know all the possibilities.

It's not the battery that is causing this. Before when it was sputtering it was just because of a weak battery, this is something different.
Also no the battery light is not on at all.

ok well what im saying is that IF the battery is low, it COULD mean that your alternator is not charging the battery, causing the car to depend on the power from the battery to operate. IF the alternator IS bad, it will cause the battery to run down. Start the car and remove the positive terminal from the battery. if the car dies then it is your alternator or possibly wiring, or fuse.

A D16Y7 in a 1993...


I'm sure there is some sort of rigging going on there...


Has it always ran like this?


CEL's?

B20DelSol

Right???....the Y7 is an OBD-II engine...the 93 civic is an OBD-I chassis...

What ECU does this thing have?

This makes me question if it has the right injectors or if it has a resistor box on it or not?

redtherocket

Indeed... Needs to be a P2E for the Y7..


Since the Y7 uses a 3 wire IACV, rear O2 etc... Its guaranteed to still have the OBD1 D15 intake and ECU..

PerfectionIsKey

NO CEL's at all, when we first got it, it ran like a damn champ. Almost to the point where i DID NOT believe it was a y7. I had MULTIPLE friends come over and try to find any modifications and none at all. I don't know much about how the swap was put in, so idk if there was any rigging. I do know it was a 96-00 platform motor though


Okay, so you want me to turn the car over and start it, and take the POSITIVE TERMINAL from the battery off and if the car dies that mean's its the Alternator/possible wiring issue/ or a fuse problem? Also the POSITIVE TERMINAL is just the black wire that is looped at the end that is tightened down by a nut right?



Not sure what ECU it has, As the car is dominantly driven by my father and he HATES if i even touch it(Even though i work on 9/10 of my friends cars, worked on his 30k$ truck, worked on my mom's car, which she has had for around 12 years which is an intrepid, which is ARGUE-ABLELY THE WORSE CAR MADE IN HISTORY, never has ran like a champ since day one with 15k miles.) so i can't take off the fender and check the ECU.

How would i know if the injectors are correct? and what does the resistor box look like?

redtherocket

Take a picture of the engine bay... And get the ECU code... Its on the passenger side under the dash. There is a kick plate covering it..

Now.

Before jumping to conclusions, I would cover the basics first..

If it always ran like a champ, then I would suspect some sort of maintenance issue...

Or possibly a wiring issue has become present from "wear and tear" since the swap...

PerfectionIsKey

So under the dash on the passenger side there should be a "Kick plate" i need to remove to get the code? alright

Okay here's daily driving for my dad:

Drive it rough and tough, high RPM's for the first 6-7 months he's ha this car
10-15 LONG burnouts on our street(He knows better yet continues)
just basically beating on it

I know for sure i'm going to do a FULL tune-up on the car, fresh oils and all. I have some really nice Syntheic oil(moble 1 i believe) that i was saving for my car but i have so much of it i'll use some in this car

Dude...aren't you like 18?

PerfectionIsKey

Kinda irrelevant? but okay.

B20DelSol

so you are 17 and have been working on your moms car for 12 years...just comparing experience...sorry...

Anyways, any ideas yet as to what it is.

PerfectionIsKey

NO NO NO lol my mom has had the car for almost 12 years now(more roughly towards 10 years, ill just say 11 to be practical lol) i tend to not be very clear, my mother has had her Dodge Intrepid for around 11 years. I SWEAR TO GOD, this car is so bad to the point i would almost drive a ******* pink Prius over it. It is literally that bad lol. Idk how long it has been since i've worked on it but anything i can do to help i try to help out. If it's something as simple as changing the brakes and oil or something as complicated as of right now her Heater core just went out. So i have to rid out the WHOLE dash and the car is pretty tight in there and tear out a bunch of things to get to it. I'm not the most experienced , or the most talented in working on cars but i am always VERY grateful of all help i get on here and friends and love to do it.

Well gotta start somewhere.

PerfectionIsKey

Since a buddy of mine has a lift, i thought i would just wait until this weekend and pitch in with my dad to clean this car up and do a full service. I mean i drive the car here and there and i would like it to be running good and clean. So i'm going to pull the SRS code(It's been on since day one) check for any hacked Harness wires/cords. Clean up some more greese and dirt. Thinking about getting rid of the stock air box because i have a new intake and air filter i can throw on. Might just buy a new OEM one not sure yet. I bought a valve cover from the local junk yard for 10$ :D Was actually really clean , so i'ma polish it up and paint it. Just basically get the engine looking and running nicer.
