I have a 95 neon that is almost paid off, i just spent 600 on a new AC, and 500 for tires and alignment. Now the light is on and one place is telling me it is the EGR valve and another tells me i have blow by. The car runs like hell. It spits and sputters and smells like burning oil. I have the code that the light flashed at me. It spit out these numbers
1 2 4 3 4 3 5 5 Anybody have any idea what to do so i don't get nickle and dimed to death?!?!?! Any advice would ge GREATLY appreciated.

It sounds like it is the EGR vavle causing your rough running. Do a full tune-up, plugs, cap, rotor, wires, fuel and air filters and an oil change. Most places can replace your EGR valve fairly cheap.

From what I remember I think the number 1 2 4 3 4 3 5 5 means, the 12 just tells you that the error message is starting, the 4343 I think is the error code, and the 55 means the end.

In case you ever need to read the codes again here's the list so you can double check everything and don't have to take random people's advice :)

Code Description of Trouble Code

11 Timing belt skipped 1 tooth or more from initial learned value;
Intermittent loss of either camshaft or crankshaft position sensor;
No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles
13 No change in manifold absolute pressure (MAP) from start to run
14 Manifold absolute pressure (MAP) sensor voltage out of range
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02 sensor problem (oxygen sensor), upstream or downstream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle position sensor (TPS) out of range, or disagrees with MAP
25 Idle air control motor circuits problem, target idle not reached (+/- 200), vacuum leak found
27 Injector control circuit problem
31 Evaporator purge flow monitor failure or evaporator solenoid circuit problem
32 Exhaust gas recirculating (EGR) system failure or solenoid circuit problem
33 A/C clutch relay circuit problem
34 Speed control solenoid circuits problem
35 Radiator fan control relay circuit problem
37 Torque converter clutch solenoid circuit or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control circuit problem
Auto shutdown (ASD) relay control circuit problem
No ASD relay output voltage at PCM
Fuel level sending unit - volts out of range
Fuel level sending unit - no change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too high
47 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal controller failure
54 No cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure - SRI mile not stored
63 PCM failure - EEPROM write denied
64 Catalytic converter efficiency failure
65 Power steering switch failure

You should go for an EGR block off if you are going to have work done on the EGR anyways, this will cause the check engine light to remain on all the time since the EGR system will be actually failing, this is supposed to make the car quicker, not faster, just quicker, lol...

what is an EGR block off? I keep getting the egr codes as well.

Hey man, when i had this problem, i just did a tune up. Like plugs, wires, belts and what not. Error code went away. I would try that first. I took it to a shop and they quoted me some rediculous number to fix it. The plugs and wires and what not you can do yourself. Hope this helps. I don't have my neon anymore but it was a great car while i had it.
