Car shuts down while driving down the road

I have a 1998 Chevy Cavalier with 292,000 miles on it. It has the 2.2 L engine with a 5 speed manual transmission. I recently drove the car through a flooded area in the neighborhood. Since then, the car will stall but it only seems to do this when the weather is wet or damp. Once it is dry, the car will run fine. I had a tune up done prior to driving through the water but did not experience any problems similar to what is currently happening. The spark plugs and wires were replaced during the tune-up but have not been changed since. I have replaced the following since the flood incident - fuel pump, air filter and coil packs. I'm not sure if this problem is electrical or fuel related. How can I find out which on eis causing the problem? Also, when the car stalls and is downshifted to a lower gear and the clutch is released, it will not restart while rolling. Any ideas on what the problem is?

The car runs fine at startup when it reaches normal operating temp it starts spitting and sputtering, backfiring then quits running and wont start until it cools down, the only codes it gives are crankshaft position sensor and camshaft position sensor range/performance, both of which I have replaced to no avail and it is still giving me the codes and on the anylizer it says that the egr, eva, cat, and the O2 sensors are all failing what is the problem?

I was driving in a snowstorm last night and hit a patch of black ice. I managed to get the car under control but when my tires grabbed traction the car came to a dead stop and turned directly onto its side. After about 30 minutes of the car sitting on it's side, the tow truck came and leveled the car out. The car started right away with no problems, but within 5 to 10 minutes the car died and now will only turn-over but not start. What should I do to get my car running again? I am a student with a 3 week old baby and I am beyond broke for the next couple of weeks. I don't have the money to put the car in a shop until they decide what is wrong with it. Because right now they say they have no idea until they look at it.

My 98 chevy cavalier will start but as soon as you touch the gas it will die. Before this happened all of the lights on the dash board were coming on and off like the engine light the brake light all them.

I have a 1998 cavalier 2.2 liter automatic transmission that after running at highway speeds 55-80 stalls at stopping. I put my car into neutral, start it up (has no problems restarting) Then when I shift into drive from neutral it clunks hard, then clunks hard again from 1st, to 2nd gear, then clunks again but not so hard from 2nd to 3rd. I would assume that this is the motor mounts, however it only seems to happen after the car stalls. My check engine light turns on and off pretty randomly, and would assume that the light itself is malfunctioning. The car does not stall at every stop, and never stalls if not brought over 45, or if the car does not make it to standard running temp. Ive recently done a full tune up with the exception of the coil pack module.(Coil packs have been replaced, just not the module that holds them) I am unsure of how to check for vacuum leaks, so some VERY DETAILED information on doing that would probably be a great first step, But in all honesty I am NO MECHANIC, so I cant stress enough on detail.

The error codes read as following :

P0742
Definition:TCC stuck on
Explanation:
commanded off by the ECM - TCC slip detected after off command
Probable Cause
1. Solenoid Failure
2. Open or short circuit condition
3. Blocked passage in transmission
4. Check transmission range switch for proper operation

P0122
Definition
TP(throttle Position)sensor
Explanation
The Throttle position signal is used for various systems in the vehicle.
Probable Cause
1. Sensor open or shorted internally - replace component
2. Check connector and wiring to sensor

P1404
Definition
EGR valve stuck open condition
Explanation
While monitoring the EGR valve pintle position the ECM detected the closed position sensor voltage higher the learned closed position voltage
Probable Cause
1. Failed EGR valve
2. Carbon blockage of the pintle.

Thats all the information I could gather about the codes. All of this is practically Chinese to me, so if you could at least tell me what to fix in order to have my car in good running condition, whether or not its something I can do by my self, and if it isnt something to try doing alone, about how much to expect for cost. Or if the car is even worth fixing. As I said before im far from a mechanic, but I am willing to try to fix it my self if its not to complicated.

Can someone hrlp please

We had a the same problem with our Chevy Cavalier and we spent a ton of money having everything fixed, cleaned or replaced. It took us a VERY long time but we were finally able to find the root of the problem and permanently fix it ourselves.

Ours turned out to be a bad Torque Converter Clutch (TCC). You can easily check to see if that's what the problem is by disconnecting it, driving the car to see if it happens again. If it does not then you most likely need to replace the TCC (they used to be around $100.00 at the auto parts store). We just left ours disconnected and the problem was solved (although replacing it helps with the gas mileage and is probably needed for emission testing).

I hope this helps you.

Recently, I would be driving my car (however long, whatever distance) and it would be fine. I'd stop at the store or something for 10-15 min or whatever, and start my car up. It starts kinda rough, and when I put it into gear and push the gas pedal, it kind of sputters, and eventually stalls out. After trying to restart it multiple times, it finally catches. And after letting it sit for at least an hour, it starts up, and runs fine. There sometimes is still a little "sputtering" when idling at a stop light, but other than that, when I get going its fine. What would be causing something like this? Thanks for the help!

I'll definitely look into those, thanks! But if it helps, today it is pretty cool, and rainy and it didn't show any signs of wanting to stall. Where yesterday, when it was stalling, it was pretty hot out. If that could effect it at all.
