92 Toyota Pickup manual 4-speed 2.4 ltr. Water dissappearing, at first thought it was a leaking drain plug but replaced that and problem still there. Have replaced the radiator cap. Radiator is less than 5 yrs old. No apparent leaks I can find. Adding at least 1/2+ gal water every few days. At times when I shut truck off I hear something like a scrubbing sound coming from under the hood for several seconds that fades out. I've heard same noise once or twice when driving, but not as good because of other road noise. Not always, but at times when driving I feel a distinct surge in power, as if I was pressing the accelerator and letting off. Normal vehicles smoothly decrease in speed when letting off accelerator or when giving it gas, but mine sometimes abruptly slows and surges. Reminds me of driving a go-kart...that distinct connection between applying the gas and letting off. Same happens at times when at idle. HELP!

From a 2001 Toyota Avalon. The dang thing is stuck in the "OFF" position. Of course I tried different keys, lubricants, rocking the shift lever, steering wheel, etc. but it won't budge. I'm certain that the lock cylinder itself is bad. So I went ahead and bought a new cylinder and by examining it I figured out that in order to remove the existing cylinder I have to first get it to "ACC" then depress a release pin on the underside. Wonderful. If I could only get the thing to budge, it would be a snap! Next I tried drilling out the core. I don't know what kind of steel is in those things but I ruined two titanium drill bits and made almost no progress. So now I am back to trying to force the thing to move to ACC. Anyone have any ideas? :wall:
