My Neon Is running badly
well i got a 1996 neon today for 1300.. it was running fine and then i parked at home for a couple hours.. so when i got back in the car the gauges didnt work and it kept dying.. it dies at stop lights and i have to hold the gas pedal down to start it.. anyone know what that is?... auto zone said it was a map sensor i dunno

RE: My Neon Is running badly
Try this and thank Squee when you get the chance.
ON-BOARD DIAGNOSTICS
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.
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 MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control 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

RE: My Neon Is running badly
It didn't work because you did it wrong. But heres what you've got going on.
P0108 = Map Sensor Voltage Too High; Map sensor input above maximum acceptable voltage.
P1299= Vacuum Leak Found (IAC); MAP Sensor signal does not correlate to Throttle Position Sensor signal. Possible Vacuum leak found.
Change the hoses that come off the throttle body. Change the gasket that goes between the throttle body and intake manifold, change the o-rings on both the Idle Air Control, Throttle Position Sensor and the Manifold Absolute Pressure snsor (its on the intake manifold between intake runners 1 and 2).
Reset the PCM by removing the negative battery cable for 30 minutes to 2 hours and then start the car. Wait to seee if the CEL comes back on.
If it does then your IAC is probably bad go ahead and get a new on.

RE: My Neon Is running badly
The process to retrieve your codes listed above is correct, but they listed how you read it for the older first gen Neons. For the newer Neons with the digital odometer it will give you the codes through it. Instead of your mileage it will put up the codes all of which start with "p" and are followed by 4 numbers. When it is done giving the codes it will tell you that it's done or if there aren't any codes it will simply say that it's done or something like that.
