OK. I was going to say that if it's bucking, then I'd suspect your Cam Position Sensor. On 01-05 NB's, they can eventually short out due to heat causing some interesting problems.

It is not as sharp as it can be with the Miata but that may be due to the 6 vs 4 cylinders and/or auto vs stick or even much newer drive train isolation. It is a softer version of the miss I get, rarely, in the Miata. Ease up or press harder on the throttle and it stops. I would suspect plug wires but it has coil on plug. It is the light/part throttle that has me puzzled. Ralph Alder Team Orphan Aerodyne Bryan Wyatt wrote: Can you describe the miss/hesitation further? -Bryan --- On Wed, 3/24/10, Chad J.
