I've got a 96 Integra LS, with what I think is an electrical problem but I'm not sure. One of my friends tells me its either a bad ground or the dizzy, another is telling me it could be the ECU.
Car starts fine and idles perfect for about 30 seconds.
Tach needle twitches first then bounces violently with no effect on the motor for about a minute.
Then the car begins to sputter occasionally
RPM's fall to zero and the car dies.
What I have replaced/fixed:
Replaced Fuel Filter
Replaced Ignition Coil
Battery & terminals are fine
Wires and plugs have been replaced in the last 10K
It used to only do this while driving, the rpms would bounce a little with no effect on the motor but every once in awhile it would cause the car to jerk. And this problem would come and go, happen one day and not the next with no change in the temperature outside.
How high are the RPM's jumping up to? Is it revving up and down while this is happening?
The jumping gets progressively worse. Starts off jumping 200-300 rpms then jumps as much as 4000. The car does not rev at all, it sounds like its just idling normally. But after about a minute or so of this the RPMS drop to 0 and the car dies.
Hmm dont know what that could be . I was going to say that if the car is idling up and down with the RPM it could be a vacuum leak but what your describing doesnt seem like that. Sorry I could not be of any help.
This really sounds like a bad ignitor module (i.e. ICM). I've had it happen to me on my old car. The tach would jump up/down and the car stumbles off and on. Eventually it'll give out and the engine will stall and you won't be able to restart it.
