Vacuum hose final connection to cylinder head. They look like sensors.

Toyota Corolla 1988 4WD 1.6efi 240000 miles
The fittings that connect to the head and there are two of them are made of plastic which obviously being plastic and so small are both broken probably due to engine heat and the hoses connected to them at just sitting there and its running rough on idle and when the aircon is turned on. If I know what these fittings are called I can order new on ebay so Im looking for the name of the parts, I cant just order vacuum hose engine sensors they must be called something, widget, gizmo, etc?

Intermittant starting when clutch pedal is pushed in.

Toyota Corolla 2001 4 dr., 5 speed std. trans. w/OD, 1.8 Ltr. engine 119750 miles
Toyota dealership suggested problem may be "sensor" at time I delivered to dealership. Toyota replaced clutch switch Assy. According to invoice. Car starts a little better (without pushing in pedal so many times) but still will not start at times - e. G. , have to push clutch in several times(3 to 4) and while holding pedal in, I rotate my foot on the pedal.

Still have problem with intermittent starting. Some time it will start with the 1st push in of clutch. At other times, I push the clutch in 1-5 times(estimated) and have to "twist" my foot on the clutch pedal while holding all the way to floorboard. In other words, I'm having to move the pedal while holding it to floorboard. It has eventually started when I do the "twist" on the clutch pedal. Any suggestions for correction of this problem will be appreciated.

Intermittant engine management light.

Toyota Corolla 2002 Corolla 46000 miles
Hi, my engine management light comes on whilst driving maybe once a week. Then goes off after I restart car. I have had the camshaft sensor replaced as this is what the fault code was signalling. However, the light still comes on but not so often as before. I have had many different diagnosis from garages /mechanics (without seeing the car). I have been advised to get the serpentine belt changed, timing chain slipping, wiring fault or sensor is misplaced. Can anyone shed any light without me having to spend a fortune please? It is a vvt-i petrol engine. Thank you

ABS light on

Toyota Corolla 2007  88258 miles
The ABS light turned on, I cleaned the front wheel's ABS sensor and it turned off. As I started the car again, the light was on, I removed it and the next time I started it was on once more but this time there was no way I could remove it. How can I reset the ABS system?

Disconnect the negative terminal and leave it that way for ten minutes. Then, with the ignition key in its position, you place the terminal and, without starting the engine, you remove it and put it in on 4 times. That way it will be reseted. Good luck.
