car cutting out - all car problem

[BarnDog296]

I have had alot of cars in the years ive been driving and ive noticed a problem with cars in general that I always assumed was just kinda the norm. But maybe its b/c ive always owned older cars?

Sometimes I really dog my car harder than normal (maybe it hasnt always had enough time to warm up really) but I will go out and just ride it like hell to test out something new I have installed or put into it. Well tonight I did put it through it paces and MAN it was a BLAST to drive!!! But thats a whole different story. Anyway I am headed home from hanging out with some buddies and my car just kinda dies when I am in neutral and about to drop to second to get on an on-ramp onto the highway here in Atlanta. Now earlier in the night, it was having a problem starting and just dying on me when I would start it up, but nothing that putting my foot on the gas couldn't fix.

Now I have noticed that my other cars would do the same thing when I would dog on them hard they would cut off when I would finally drop into the lower RPM range than the 6000 or so I was pushing it into.

Now is this a problem with dropping RPM too fast or what? am I messing up the ECU b/c its getting soooo much air and sooo much fuel for awhile that when it drops down to reasonable levels it just doesnt know what to do or what?!?

i feel bad for your 240.... the dying just sounds like its boggin out from the overflow of fuel/air at the high rpms....for all of us, please don't beat on your 240..go buy a honda if ur gonna do that >.>

Honestly I dont beat on it that often I really am not worried about if something bad happens. I can honestly replace just about anything in the car (and im not drifting it in the streets or something), but I am just wondering why its doing what it does. I am basically taking it to empty backroads I know about in Georgia and doing track runs, but nothing too crazy like 100MPH or anything like that. I am usually about 20-25 over the speed limit, something they cant take my license away for, but enough that its still fun.Also with the work ive done to it 6000RPM really isnt that bad, the car would change gears at 6500 RPM when it was an automatic with the work I had done. I honestly dont dog on it most of the time, but come on man! You have a FUN car to drive, higher torque than an S2000 with a good 50/50 weight distribution. GREAT suspension setup and the works, you dont spend all that money on a car to get it the way you want it to NEVER tear on it.I am just wondering after a time like that why it is faster to die on me than normal?
