hi!
sometimes, at a varying point between 2k and approximately 4.5k rpms, the engine dies completely, drops a couple of hundred rpms, and then comes back again. This only happens when very little throttle is applied (between 10-30%). At full throttle the engine functions perfectly.
Anyone know what might cause this?
My car is an 1998 euro spec ITR (b18c6).

 

Is your car completely stock or are there any modifications?

 

Supersprint 4-2-1 header, Ractive cat. replacement, Apexi N-1 exhaust, AEM CAI and MSD plug wires.

 

pull those MSD plug wires off and use stock ones. I bet that helps.

 

Why is that? The MSD plug wires came on today.

 

Well you did not say that before..........
So let me take another guess, Your muffler bearings are seizing up causing the hesitation.

LOL!
How about a fresh rotor and cap.

P.S. Maany people do fins that the stock or NGK wires have worked better than the MSDs.

 

BTW my car has about 150k kilometers (94k miles.)

well, was it sputtering and dying before or after you put the wires on?

 

Before, Changing the plug wires did not do anything, either good or bad.

 

Wiggle your throttle position sensor while the car is idling to check for a bad connection and/or do a Helms test on it.
