When I drive my car when I hit about 2500 to 3500 Rpm my car lags like the a/c is on, but its not, I thought it was my plugs or maybe my coil but it wasnt. DO you think it could be my fuel filter? I dont understand why its doing it.

We don't have fuel filters like most cars. The only thing we really have is a screan that covers the inlet of the fuel pump in the tank and thats it. How many miles on the car?

like 75000 i think

ok so what else that happens is that once I end up at about 2500 rpm, and I stick the clutch in and give it a few quick revs, and it backfires every time I rev it almost like there is a lot of pressure build up and then when it gets past about 5 to 6 grand everything acts like its fine.

what year is your Neon? i'm changing the fuel filter in my Neon but mines a 1995.

injectors might be clogged.... could try running some fuel system treatment through, but sometimes that will only make them clog up more.

leak in the intake?.... just my two cents....

I put fuel treatment in it, and that didnt do anything for it, my car is a 2001 btw, I just dont get it, it seems like every time I take it to the dealer, it gets messed up in some sort of way. Im sick of it, and now Im getting this knocking sound like a rod or somethin but it only happens half throttle. So my car is just a rolling thorn in my side... HELP!!!

make sure your plugs are in tight... and check/torque them with the engine COLD. my 01 did that for a while and the #3 plug kept working its way loose because i always tightened it hot.

I did do that, and it still didnt help, It seems to be getting worse, not to mention that that when I am gettin ready to stop, and I put the clutch in the car stays around 2500 rpm until my car comes to a complete stop... and on top of it all, my IAC sensor gives off a loud hum after I turn my car off.

are you getting any codes? the IAT or the TPS could be bad, maybe possibly the O2 sensor. all of those things contain the type of voodoo that would cause your drivability problems.

I havent check yet, I was gonna go buy an OBD II reader, but im short money, Ive heard that autozone will scan that shit for free, but I just havent had the free time to get out there. Idk all I know is that its getting really really frustrating, know what I mean?

theres a way to get the codes by flipping the key on and off a few times... ill let you know if i find it.

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.
2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.
A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition for a neon.

There ya go.

I thought that was only for 95-99 with the whole key turn thing. I guess I'll try it. I talked to a couple of mechanics they said it could be my O2 Sensor or my TPS sensor, so Idk.
