Today my car was acting up scary. When i first started it for the first time today, it was fine and i drove for like what.. 30 min ? and then left the car to do some errand.

Come back, ignite, car shaking and rpm goes below 500, and then slowly dying, and then engine shuts down. Tried again, still same, engine died within 10 seconds. Tried AGAIN, and then this time i pumped some gas (is that bad ? ok ?) still dying, and then afte ra while, engine is shut again.

Then next attemp i kept gas going for a while, and the rpm finally stayed at around 650 , a bit low compare to normal.

Drive for a while, and then went somewhere again, and comes back, stil lthe same, except this time, engine will shut almost immediately after ingition, much faster than previous incident.

so i left the car there for a while, and comes back, viola, everthing back to normal.

Is it the "idle control" ? as my friend guessed ? Or another possible reason we came up with was maybe something to do with fuel tank. For the past few months or so, i have been keeping my gas tank quite low, say maybe less than 1/2 or so, because of the gas price, i just fill a bit whenever i feel like it.
Yesterday was the first time i actually fill my car up to almost full.

Is it because there were too much oxygen in the fuel line ? or ?? any suggestion will be appreicated.

I am not sure if i should bring it to a dealer, now everything is normal, and i probably can not reproduce this problem.

=-(

 

Our cars have shitty ignition or something, My car always shudders when I start it until I drive for a few minutes. It has shut off on me 2 or three times before. Nothing to show the dealer though.

 

Sounds like when the minuture vent hole on my MC gas cap was plugged.

 

MC gas cap ? what is that ???

 

Actually I had the same problem. The dealer told me that in the winter, gas companies create a different blend of mixtures/additives than in the summer. This blend boils/vaporizes at a much lower temperature than a summer blend. When you drive your car then shut it down for say 15-30 minutes and it is fully warmed up, the heat from the engine vaporizes the fuel in the lines very close to the injectors/engine. This is why the engine stumbles and can even stall for a minute or so when you first start it up. This situation is most likely to occur on a slightly warmer than usual day in the middle of winter or when you have driven the car in a manner that makes the engine operate near peak temperatures (stop and go driving or high speed driving for awhile). The best thing to do is to get it started then give it some gas for like 15-30 seconds to get fresh fuel flowing again. This should never happen in the summer.

 

This theory sounds plausable. I guess i will try your method and see what happens. Its really unpleasant to see my car all caughing and dying ! lol

 

If that dealers theory was the case, then all cars would have the same symptoms. And I don't lnow anybody with the same problems as us in such a new car.

 

Maybe, but most cars are not as finicky as the CLS is for higher octane gas. Gas companies do in fact change formulations for winter vs. summer driving. Not sure if it's the reason we are seeing it in this thread but it certainly can not be ruled out.

 

On the other hand, yes, thats true. I have a 3.0 first gen, and we al know there are a shit load of v6 accords out there that have the exact engine and setup as i do. Had a couple friend who has 3.0 accords, and never heard similar problem.

Hmmm..... perhaps i should not kid myself and bring it to a dealer. But then, now everything is fine.. i don't konw what to do, i mean if i bring it to the dealer and i can't reproduce tihs sympton, that would be a waste of my time.

Maybe our ignition system just really suck ?

 

I had that problem, and the dealer had to replace a part. They said it was kinda common. I told him that the RPM's drop low and then pop up again for a sec then will sometimes die, and they said. Ohh no problem bring it on in and well fix it.

 

What you described is EXACTLY what happened to me the other day !! Drove stop and go for 45 minutes, stopped to get groceries for about half an hour and on restart it stalled. Then when i started again and began backing out of the spot it started to shudder so i put it in drive and went forward instead. Within a couple of minutes, no problem, and it was a warmer day than usual. Amazing how accurate you described it. Thanks.

 

I seem to remember there being a TSB for this problem on the 01' CL's...sorry don't remember the specifics though.
