After all I've gone through with the bucking, I'm admittedly still in the "not sure if it's really OK" phase. I know when it's not working, but can't quite be sure that it's working right yet, you know? My questions with the AC have been around since I got it. I don't remember Junior's AC working like this (then again, I had it pulled anyway)...

If the AC is cold and the car runs well leave well enough alone. How much of a “bog” are we talking about. Remember the AC cycles and if it’s coming on as your accelerating you’re going to feel a power loss.

Of all of the sensors of the car besides O2 sensors, I'd be most likely to keep one of these with a spare on hand. Moving on though... Assuming my bucking issues are solved, I'd like to address what to do with my AC. Often when it's running, I notice small "pulses" through the gas pedal as well as a whine that increases with RPM's. In addition, the engine seems to bog between 3 and 4k when accelerating. This only happens when the AC is on. Is all of this normal? -Bryan --- On Sun, 6/22/08, Larry Alster <[EMAIL PROTECTED]> wrote: From: Larry Alster <[EMAIL PROTECTED]> Subject: RE: [Miata] 2002 Bucking - 100mi Update To: [EMAIL PROTECTED], "'Miata Power List'" <[email protected]>, "'Miata Mailing List'" <[EMAIL PROTECTED]> Date: Sunday, June 22, 2008, 9:37 PM I see your point but the MSM is extremely hot under the hood too so I still might keep a spare in the race trailer.

On 99-00 cars, the sensor is on the front of the valve cover on the other side of the intake cam sprocket, whereas on 01+ cars, it sits atop the rear of the valve cover (very hot) where it probes into engine oil (even hotter) at all times. Not an ideal arrangement. If Mazda didn't have to fit the VVT actuator to the front of the intake cam sprocket on 01+ cars, they probably would have left it in the original position. In short, if your sensor is on the front of your valve cover, I wouldn't worry about it--there are plenty of other sensors that'd likely break down first. -Bryan --- On Sun, 6/22/08, Larry Alster <[EMAIL PROTECTED]> wrote: From: Larry Alster <[EMAIL PROTECTED]> Subject: RE: [Miata] 2002 Bucking - 100mi Update To: [EMAIL PROTECTED], "'Miata Power List'" <[email protected]>, "'Miata Mailing List'" <[EMAIL PROTECTED]> Date: Sunday, June 22, 2008, 9:20 PM Yea it does, I thought that was the point. That the sensor on the cam was the problem.

My MSM has one so I might keep a spare around.

I should have clarified that I had replaced the Cam Position Sensor. For 01+ owners, this seems to be an almost common necessity, as the plastic sensor is constantly exposed to hot engine oil. -Bryan --- On Sun, 6/22/08, Larry Alster <[EMAIL PROTECTED]> wrote: From: Larry Alster <[EMAIL PROTECTED]> Subject: RE: [Miata] 2002 Bucking - 100mi Update To: [EMAIL PROTECTED], "'Miata Power List'" <[email protected]>, "'Miata Mailing List'" <[EMAIL PROTECTED]> Date: Sunday, June 22, 2008, 8:52 PM Is this the sensor on the intake cam??

I've done everything but drive it HARD (in every case, bucking happened during normal driving anyway) including running the AC. There are some things that the AC does that are still scaring me, but at least the car doesn't seem to be bucking :-) On the other hand, I changed the fuel filter today. After washing my hands about 5 times and showering twice, I still smell like gasoline! Of course, I did have some running down my hands and arms and it'd just sprayed in my face (accompanied by a surprised exclamation of dubious origin). Seriously...I'm glad I'm only going to ever have to do this a couple of times ever... -Bryan
