I was driving night before last for about 50 miles and noticed that the bucking was still occuring even when the car was warm, so it seemed to be getting worse. Last night I drove it a short distance again and it was even worse, almost to the point where it was undriveable. At first when I just put my foot on the throttle it evened out, but now there is a noticeable dip in power and it stumbles. I did a little research and found it could be a whole host of things, one being the TPS. However, Honda in their apparent greediness and willingness to screw a customer decided to make the TPS a non replaceable part. So if you go to the parts counter at Honda and ask for a TPS they'll only sell you a throttle body with the TPS attached, which is said to be a $700 part (I haven't actually been quoted on a price, but knowing dealers that doesn't sound too exagerated). Damn that shit pisses me off, it's criminal. I mean a TPS is what a $40-$50 part tops?
Luckily you can buy aftermarket sensors, however you still have to side step Honda's idiocy by dremeling a slot in the fasters that hold the TPS in place in the throttle body so you can actually remove it.
Today I decided to take a look under the hood. I found one interesting thing. Where the intake hose connects at the throttle body I found that the clamp that secures it was loose, really loose. It used a fasterner threaded into a nut welded on the clamp to hold it in place. But the fasterner was MIA and the clamp was just dangling. I reattached it with a new screw and went for a drive. Better than last night but there is still something amiss. I needed to change the oil so when I was at the autoparts store I went ahead and got a fuel filter too. I hadn't changed it since I've owned the car so I figured it would be a good idea.
After changing that it felt better yet, no violent jerking like last night, but still not 100%. Feels like something is missing when I'm accelerating. Next I'm gonna try cleaning the MAP sensor and throttle body and check my plugs. I'll work from there but at least its driveable.
