Ok i know sputtering has been discussed, but ive searched, and every case is diffrent...heres mine, help me out please...

All started with the skunk2 manifold on my 95 GSR...
- Never messed with the timing..
-NEW plugs, rotor and cap, and plug wires.
-Took off my Fast idle thermo valve (capped lines)

I changed the plugs 3 times in the past month, and the car runs great for about 2 hours, than it starts to sputter again. I take the plugs out, and they look fine?

Ive noticed ive been burning a oil, not alot, but enough to notice..No leaks though.

No CEL's.........Sometimes i get code 43 (fuel pressure) but they say thats just the 02 sensor. i reset it every time i get it..And that goes away..

Ive been patient with the sputtering, as it happens in all weather, every gear, any RPM..Ill just be on the gas...(0-WOT) and it will just "skip" and go back to normal..

Than tonight, which really TICKED me off... Im driving and it is just BAD. Im stopped, i can barely MOVE, i press the gas, and it almost dies.. i floor it, and it shuts off.. Start it up, once i get about 4k..it goes back to "every couple seconds" it studders..

Im so god damn pissed at my car, u dont understand..WTF is wrong with it?!?! Why would it foul plugs out so fast? (if thats the problem) Help!!!!!!!!!!!!!!!


Picture is for you, people who only look at threads with pics

 

Even though you have posted most of this, can we get the complete picture please?

Engine (Code, Year, Automatic, Manual, Original, ALL mods)
ECM (Original with engine, or swap, Wich one)
Wich Sensors/Valves are installed on your Manifold.
Did you "not install" the FITV, or just "bypass" it with alternate coolant lines.

Just a wild guess, could your FPR be seeing inadequate vacuum?
I don't see a MIL code 43 in My Helms. . .
I have 2 45s though, one is too lean, one is too rich.
Her are the codes I see:
P0133 (61) Primary Heated Oxygen Sensor Slow Response (Sensor 1)
P0135 (41) Primary Heated Oxygen Sensor Heater Circuit Malfunction (Sensor 1)
P0137 (63) Secondary Heated Oxygen Sensor Circuit Low Voltage (Sensor 2)
P0138 (63) Secondary Heated Oxygen Sensor Circuit High Voltage (Sensor 2)
P0139 (63) Secondary Heated Oxygen Sensor Slow Response (Sensor 2)
P0141 (65) Secondary Heated Oxygen Sensor Circuit Malfunction (Sensor 2)
P0171 (45) System Too Lean
P0172 (45) System Too Rich

Take it to AutoZone and have them tell you specifically wich DTC you are throwing.


PS:
You are not using silicone hoses to your FPR and other sensors ae you?

Its a 1995 , OBD 1 Integra GSR 5 SPEED Manual. Intake/Catback/ Skunk 2 Manifold. ORIGINAL MOTOR! I Have the IAC, and IAT and both of the sensors on the TB hooked up. The FITV i have it removed because it was broken, and just plugged both those lines. They are not connected. (Could that be it?)

Silicone hoses? Whats the diff? i dont think so..i think there oem rubber..

 

Map sensors can cause some crazy engine performance at anytime, and don't always set a code. Sometimes they still test good with a vaccuum pump and DVOM. It is sometimes best to plug in a known good one and see. I would say check all connections to all sensors mounted on the new manifold.

 

Put your stock one back in.... and see if that fixes it.... heres what I think is going on... Somehow your car is reading that your engine is not warm and it is injecting more fuel into the CC to warm the car up and that is causing your fouled plugs... just a thought....

check the vacum lines, if you need a picture call skunk2 and tell them you need the instructions to hook your vacum lines up and the will e-mail them in minutes(thats what I did) they might also tell you whats wrong, and reset your ecu if you havn't done it yet!

anyone?

 

bump

 

Still having problems. Did you check all the wires to make sure they are on the right plug. Maybee you mixed something up when you extended the plugs.

 

Well, i never exsteded any plugs, and they all still work, cuz when i do take them off, i throw a CEL....I just cut them out of the harness for more slack..

are still having that fuel code occurring? and how long did the problem started after you installed the manifold? Does the problem only occurs during heavy throttle like from a stop position? and, how many mile do you have on this vehicle? becuase, I sound like a misfire is occurring.

Good thought.

Swags04:
1) When was the last time the Fuel filter was changed?
2) Can you swap BACK to OEM plug wires?

It still sounds like fuel delivery problems to me, But I'm no expert on spark.
Excess fuel "carbon fouls" spark plugs, That's part of the reason I suspect too much fuel. What did your fouled plug(s) look like? Which one(s) wre fouled? Were all of them fouled, or just one?

The HO2S voltage reading is used by the ECM to adjust fuel mixture. (RICH/LEAN).
I wouldn't count the HO2S out yet.
The trouble shooting steps in my Helms (96+ OBDII) point to Fuel Pressure as an alternate cause of this problem.

So. I suppose that leaves us with:
Check Fuel Pressure.
Have someone check HO2S.

And see where that leaves us.
If ALL of your plugs end up the same way, then it would be something like fuel pressure or a sensor that is keeping the ECM in "Rich Mode".
If there is only one or two plugs that get fouled, then we would be looking at an individual cylinder type problem (Distributor, plug wire, injector).

Best of luck to you.

 

sounds just like when my truck(a dodge ram) was misfiring.

It turned out to be the spark plug wires were bad. The insulation formed microscopic cracks, when it was damp and cold, the wires would arc to the block and misfire. These wires looked fine, and were only 20 months old from the factory(2000 truck, happened in 2001!!).

I replaced the wires, and the plugs , cap, and rotor, while I was at it..runs perfect now.

If you are misifiring, and have a cat, when that, too. unburnt fuel in the system will be burnt in the cat, which will melt it and cause it to clog/flow poorly.

Looked at my truck manual: it says that if the truck's CEL is blinking, it indicates a misfire, stop driving immediately. severe catalytic convertor damage will occur.

 

Well these are brand new NGK wires, and a brand new honda oem fuel filter.

One thing i want to get is a new Fuel line from the Fuel rail to the Fuel Filter, What are the replacement parts for this so i can get a Earls? Does anyone know! My aem intake has been stretching that...

Also, all my plugs are the same, and im going to get a FPR next. What should my fuel pressure be at? (According to if i have it at the filter)

 

Also, when i put my new 02 sensor in........They have 2 black wires, i didnt know where each went, and just stuck them in......Could that be it?!

I think its the Fuel Pressure, That Fuel Line, Or the O2 Sensor/bad cat.

 

i also just noticed that, when i just took it out, it was fine for about 10 mins.(cold start), and about 10 mins into driving it started sputtering/becoming slower, pulled less...
does the 02 sensor have effect on that?

YES! I missed that you had replaced the O2 sensor. The O2 sensor helps the ECM control the duration of injector firing. IE: when the O2 sensor has effect on Rich/Lean condition of the vehicle during and after the "warmup" period. I'll bet that the ECM still thinks it is in "warmup" mode. As far as I know, my Heated O2 sensor has 4 wires. Heater +, Heater -, Sensor +, Sensor -. The ECM increases injector duration as O2 sensor voltage increases.

 

I forgot, Could your AEM be "pinching" the line form the fuel filter to the fuel rail after the line becomes "soft" from engine heat?


I don't think this would cause a problem as that would "starve" the injectors, and I think that you haea "rich" situation.

What was the word on the plugs? All fouled? Carbon Fouled?

 

Fuel Pressure (B18C1 & B18C5):
With FPR Vacuum Hose connected: 38-46 psi
With FPR Vacuum Hose disconnected and pinched shut: 47-54 psi

If Fuel Pressure is too High:
Inspect fuel return line for piching or clogging.
Isnpect FPR

If Fuel Pressure is too Low:
Check for clogged fuel filter
Inspect FPR
Insect fuel lines for leakage, pinching, or clogging.

 

I have the fuel filter unbolted from the wall, so it does not pinch anymore


That o2 sensor sounds like it could be it! At least i hope. Do i need a new one? Or should i just check the wires on where they go again? There are 2 black ones...whats the diff?
Im not throwing a code or anything..

 

How well does the throttle cable mount to the Skunk2 Manifold? Does the cable deflection meet the 10-12mm specified?

 

Im not exactly sure what that means about the throttle cable, but its attached by a ITR bracket, and it looks OEM. It reads 0.0 on my vafc and 100% on full throttle(TP)

 

My helms shows 4 wires per the Primary heated O2 sensor. . . .
Do you only have one O2 sensor?

Where is it?
