- To Whom It May Concerned:
-
- This is epsode III on some problem about Toyota 2SE engine.
- The 1st epsode was about the Pickup Coil, I had it replaced yesterday,
- and posted the 2nd to thank those people who helped me.
- This post is about the idle speed of the idle fluctuation.
- After I replaced the Pickup Coil, I hooked up a techometer as well as a
- timing gun to the engine for a timing check. Both of these devices are
- of inductive type, that is, their signal pichup is clamped to the spark
- wire. There is a service connector for a different type of techo, though.
- I observer some drop (for a very very short duration) in the idle speed
- in between of normal (steady) rpm from the techo. The normal revolution
- lasts maybe for 20 seconds each time before a miss.
- I called the delar today, some mechanocs said it's normal for a 2SE
- engine to have some idle fluctuation (?). <---This is my firat question.
-
- My second question is when I depressed the brake pedal, the idle speed
- dropped by around 100 rpm (?).
-
- And the third question is about the idle up when A/C is on. I observed that
- when I turn A/C on, the idle speed jumps up to 1200 rpm before the room
- temperature goes down. But on some other type of cars, the idle speed
- would maintain the specified, for example, a Honda Accord automatic,
- the idle speed is at 800 rpm, with or without A/C on. Could this
- be different methods were used to compensate heavy loads?
-
-
- Your advise will be appreciated.

- BTW. I am going to check the brake vacuum booster leakage tonight.
