95 neon sputtering under acceleration
Hey everyone. I'm a new member on dodgeforums but i will be a frequent commer i'm sure because i'm obsessed with neons and i've owned one for 2 weeks now, lol. OK well here's my problem. Ever since i bought it 2 weeks ago it will sputter and won't accel fully without sputtering or being weird. It's hard to explain. But it only does it once in a while. Sometimes i'll step on it and it'll go like a bandit!! But then it'll spit n sputter sometimes when i step on it it ain't givin it it's all. Well today i replaced the fuel filter and it didn't help. I switched coils, put in new spark plugs, and the wires look almost brand new so i know it's not that. Sometimes it idle's a little rough too. No check engine light or anything, but i haven't checked to see if any codes show up, which i plan on doing yet tonight. I have pulled the injectors clean them all up and i thought it was 1 injector but i switched that out twice and i also had the fuel rail pulled and turned the car over and they all spray fine. Any help would be GREATLY appreciated, i'd do the same for anyone else.. Thanks...

RE: 95 neon sputtering under acceleration
Yes it might be your catalyc converter because when they get clogged it spit and sputter all day long because it acts in conjunction with your o2 sensors. Also check the compression in all your cylinders. Let me know what happens.

RE: 95 neon sputtering under acceleration
Well, when i was messing with my injectors, i waited for about 2 hours to let the motor cool down before i pulled the fuel rail to see if all the injectors were squirting, i pressed a pin into where you check the fuel pressure in the middle of the fuel rail and it threw pressure out real well so i don't think it has to do with the fuel pressure. But if it was my cat or 02 sensors wouldn't it throw a check engine light?? Maybe not i was told. But what i was thinking of doing next weekend is taking it to the exhaust shop and having the cat totally removed cuz in minnesota here we don't have to worry about emissions and then having all new exhaust put on and throwing a turbo muffler on there and my buddy has all brand new 02 sensors that i could get cheap from him so i'd throw them all in while i was at it and then see what happens.. Only thing i'm worried about is the backpressure needed from the cat...will it run fine without the cat and the backpressure will be fine without throwing a check engine light or cel??? Is it a good idea to remove the cat totally?? I'm a straight up mopar V8 man this is my first time owning a 4 banger which i'm lovin already.. I've wanted a tuner for a while now. But i've heard about the backpressure on 4 bangers that's needed... Maybe it won't be an issue but you guys probably know more about this issue than i do. On a v8 there wouldn't be no cats once i got it but unsure about the little 2.0. Thanks alot.. it's greatly appreciated

RE: 95 neon sputtering under acceleration
I was doing a little research on neons.org and i came across this...
So in other words... it's need a new fuel sending unit??? Because that's exactly what my gas guage is doing, and i did the dash cluster repair and it didn't do a thing to the gas guage.
SUBJECT: Run Out of Fuel with Gauge Reading 1/8 to 1/4 Full
NO: 08-28-95
GROUP: Electrical
DATE: Jul. 14, 1995
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 08-42-94 REVISION A DATED AUG. 5, 1994 WHICH SHOULD BE REMOVED FROM YOUR FILES OR NOTED IN THE 1994 TECHNICAL SERVICE BULLETIN MANUAL (PUBLICATION NO. 81-699-95054). DIAGNOSIS AND PARTS HAVE BEEN REVISED. ALL REVISIONS ARE MARKED WITH **ASTERISKS**.
MODELS: 1995 (PL) Neon
NOTE: THIS BULLETIN APPLIES TO VEHICLES BUILT IN BELVEDERE WITH A "1" IN THE FIRST DIGIT OF THE VIN # BUILT PRIOR TO MAY 26, 1995, (MDH 05-26-XX) AND ALL VEHICLES BUILT IN MEXICO WITH A "3" IN THE FIRST DIGIT OF THE VIN #.
SYMPTOM/CONDITION:
Loss of power and/or possible engine misfire. Vehicle may stall and will not restart. Check engine lamp may be illuminated. Fuel gauge is reading 1/8 to 1/4 full, but vehicle operates as if it is out of fuel.
DIAGNOSIS:
1. Lack of fuel may be confirmed by using the Mopar Diagnostic System (MDS) or the Scan Tool (DRB III) to check for the presence of Diagnostic Trouble Codes (DTC's). If DTC (Single/Multiple Cylinder Misfire) is present, continue with the following diagnostic procedure before proceeding with other diagnostics using the Mopar Diagnostic System or the DRB III along with the 1995 Neon Powertrain Diagnostics Manual.
2. Check for proper fuel pressure as outlined in the 1995 Neon Service Manual (Publication No. 81-270-5025), Pages 14-7 to 14-8. If the fuel pressure reading is less than 15 PSI, the vehicle may be out of fuel.
3. Remove the fuel filler cap. Perform the Fuel System Pressure Release procedure as outlined in the 1995 Neon Service Manual (Publication No. 81270-5025), Page 14-11. Disconnect the negative cable from the battery. Raise the vehicle on a hoist. Remove rubber cap from drain tube located on the fuel pump assembly flange. Attach 5/16" hose to the drain tube and apply a vacuum from a Fuel Storage Tanker. If fuel is present, the problem is not with the fuel tank level unit or gauge and further diagnosis of the fuel delivery system will be necessary. If no fuel is present, follow the procedure to determine whether the fuel gauge or fuel tank level unit is defective, as outlined in the 1995 Neon Service Manual (Publication No. 81-270-5025), Pages 8E-3 through 8E-4. **Most likely, the fuel tank level unit conductor elements have deteriorated and are causing the incorrect reading.** Proceed with the following repair procedure.
PARTS REQUIRED: 1 **4864020** Fuel Tank Level Unit
REPAIR PROCEDURE:
**This bulletin involves replacing the fuel tank level unit with a revised unit.**
1. Install new fuel tank level unit, P/N **4864020**, as outlined in the 1995 Neon Service Manual (Publication No. 81-270-5025), Pages 14-5 to 14-7.

RE: 95 neon sputtering under acceleration
Well there's no possible way to get it over an 1/8th tank of gas lol. That's just the way it is from that sending unit i'm assuming, after looking at that TSB

RE: 95 neon sputtering under acceleration
the TSB is referring to when the gage gets down to 1/4 or 1/8 left the car runs out of fuel instead of it saying its empty then running out
the fuel pump & sending unit are sold as one $200 setup, so if you have alot of miles it might be due for a pump anyway
, just because pressure squirts from the bleeder on the rail doesnt mean it has the correct pressure, they can still hold 25-30 psi and run but it wont run very good on that, i think the minimun required at idle is about 45 psi - if your pump is weak it will make it worse with less fuel from it having to work harder, you might have the issue the TSB is talking about
