today I jumped in the Xfire at 6:30am and without heating her up i started to drive due to being late to work. less than a 1/4 mile later, while I was trying to change the radio channel, i noticed I revving the engine to about 5k RPM because I thought I was in gear, but In fact i was in netrual. No big deal, put her in gear and approached to a light. I stopped and noticed engine is idling rough. Not rough to a point where it looked or sounded like it had a big cam or it was gonna stall, but it was rough enough to shake your butt slighly in the car. I revved her up to a 2k rpm or so thiniking it would get back to normal but nope. I started to drive and oh boy engine started to shake even worse, felt and sounded like eash cylinders werre miss firing, etc. I immediately pulled over, turned the car off. 30 seconds later I restarted to car, and everything was just fine.

Now, what in the hell was that? Any opinions? Previous experiences? It was pretty scary. I just thought maybe it had a small glitch and needed to be recalibrated. But why this even happened in the first place? Kind of worried me.

Thanks folks!

 

Ah, the age of the microprocessor. Sounds like some controller/processor got caught in an endless loop, not doing it's job.

The only thing I would ask is - how old is your battery?

 

so no big deal??

I bought the car at 38k and it now has 48k on it. The same battery. I am not sure how old it is.

 

If it's white, it's likely the original battery.

I'd go to O'Rielly's and spend $89 on a new one. My ford van does what your car did, about once a month, and I cure it just like you did.
No codes ever set - local shop has no idea what it is.

 

hmm... well, this only happened once. if it does happen again, I will replace the battery. Yes it is white. Thanks pizzaguy

 

If it is the white one, reaplce it now anyway, it will give you nothing but problems down the road and more than likely leave you stranded somewhere this winter when the temps drop...

 

Sweet!! Will do ASAP. Thanks John!

But, could this problem related to my battery? It was awkward. The car started to missfiring pretty bad all of a sudden, and a simple restart fixed it.

 

time to trade it in & get a newer one !!!!!!!!!! Great excuse !!! Honey I really need to trade it now !!!!!!!!

 

Lol, this is my second one. My girlfriend loves LOVES the car and has been nagging to buy it from me and i agreed to it. She was going to buy one 2 years ago but ended up buying something else. She is taking her off of my hands in a day or two. However, the car is still in the family And I will pick an 07 mustang GT. We will switch it whenever we feel like it

 

when you get ready to mod that GT give me a buzz

 

Do you have something for me Geno?

 

That problem may be a crank position sensor starting to act up.... that is how my Aero acted the first time at the race track... started but was real rough... turned off and re-started and everything fine. Did you get a CEL?

 

CEL???....

 

Curious, I've always read on "High Compression Engines" you shouldn't start them up and let them idle for long periods of time. Of course the word "long" is subjective.

 

went on vacation for a week,left the crossfire in the garage, when I came back noticed the spoiler up..Blood boiled for a minute thinking the house sitter was off playin in my car! only to find a dead battery.
Battery had been no problem up until that point, but after replacing the battery noticed a huge differnce on start up..turn the key and theres all sorts of juice there...where as before it always cranked and started but never noticed how slow it cranked!

also after I removed my rcm and cleaned it..after start up it ran like on 4 cyl till I cut it and restarted it then it ran like a charm!

 

I've had that happen in my truck. It was ignition cable going out. If you find it happening more often, I would have the cables checked.

 

Check Engine Light The CPS can set the light, but not always.

It SEEMS that problems with the battery almost NEVER or NEVER set the light.




um, right everyone?

 

I have had multiple cyclinder missfire when in that situation, restart clears it but I get a code that has to be reset with my Zeitronix reader. Woody

 

I would say anything is possible with a weak battery. From alarm malfunctions to door lock issues to ignition and running problems, these cars need the correct voltage at all times.

 

I agree with Mike, it isn't your battery....it wasn't sensing right position, and as you accellerated, it would only get worse. Mine would start like that once in awhile, and it finally went...
