I have a 2000 S2000 with 27k some times the car sputters between 4k and 6k and when it hit's 7k it stops sputtering the car is all stock. Looking for some info.

Thank you

 

Have you checked the oil level?

 

Have you tried a new MAP sensor? Or disconnect and reconnect the MAP sensor wiring harness?

 

happens to me all the time....voltage drop.

(but your car is stock, so you shouldn't have a voltage drop??)

 

I have alot of sterio stuff 2 amps JL audio subs & one cap 1.0 fardo could that be the prob. or a voltage drop ingition ?

 

ooh oil is level is good..

 

Just disconnect the whole thing and test.

 

No CEL ?

 

"Bucking" at slow speeds while beginning to move in 1st gear and while beginning to accelerate in 2nd gear. I have had this happen 3 times now, after stop and go driving, on "warmer" days (I live in Florida and I've only owned the car since October so it has been relatively cool). So far it has not been so bad as to actually stall the engine, but I would not be surprized if it gets worse during the summer months. I find I can duplicate the symptom if it's warm out, the car is fully warmed up, then I come to a stop, press the clutch several times, then try to start going in 1st, the car lurches intermittently as if I'm running out of gas. As soon as I get the revs up it's fine again. In case the following is related, it also suffers from low rpm drop sometimes after I let go of the gas. It will drop down to about 4,000 rpm, enough to make the engine shudder. Oxygen sensor? Emission control devices suk, especially on an S2000!

 

You shouldn't hijack other peoples' threads like this and in the other thread. You can always start your own thread as your question is really the same as the topic of either thread.

In any case, read my response to you in that other thread:
