SOURCE: 1991 S10 2.5L throttle body idles to fast

A vehicle that old will suffer from brittle and cracked vacuum lines. I would say there is a bad, or several bad lines leaking away vacuum from the intake manifold. Don't forget to check the hose going to the PCV on the valve cover. A vacuum leak will also cause the engine to stumble and miss intermittently when idling.

SOURCE: can 2008 saturn astra be dinghy towed(4 wheels down)behind an RV?

You can do it if you really wanted to. You'll need to make sure the steering wheel is secured and that the wheels are perfectly straight or you will wreck the front tires. You will be adding unneeded mileage onto the the car by having the front wheels turning. would be better and less costly overall to get trailer that you can put the front end up on.

SOURCE: opel astra headlight adjustment

two screws on each headlight control the direction the headlights are aimed. One screw, usually at the top but sometimes below the headlight, adjusts the headlight up and down. The other screw, located to one side, controls the headlight from right to left. Turning the appropriate screw one direction or the other will change the direction the headlight points.
In order to aim your headlights you need to have a flat vertical surface you can aim your headlights at in front of a level surface on which to park the car. If your driveway is level your garage door is the perfect place to aim your headlights.
The tools you will need for this job are simple. Masking tape is used to mark where the headlights are to be aimed and a screwdriver is needed to adjust the headlights. A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks

SOURCE: idling problem toyota altis

Either there is a vacuum leak causing the high idle, or
the IACV is bad or being controlled by the computer to make idle speed too high:

To change the IACV refer to the following:
Idle Speed Control (Idle Air Control) Valve Removal & Installation To Remove:

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the throttle body. Idle speed control valve toy_cor-04-18-1187.gif

  3. Remove the 3 mounting screws from the throttle body. Remove the idle speed control valve and gasket.
To Install:
  1. Using a new gasket install the idle speed control valve on the throttle body with the 3 mounting screws.
    • Tighten 33 inch lbs. (3.7 Nm).
  2. Install the throttle body.

Has anyone experienced and fixed oil leakage problem from the intake manifold and throttle body on 2001 TS Holden Astra 1.8l ? Thanks Hoffy


HI normaly the only areas i would look at other than possible head gasket,Check oil level is correct, is there is a blockage in the engine breathing side (possibly internal of rocker cover) sludged up. Or possible excessive crankcase pressure of course any one of these could lead onto the other if all the above check out ok then a cylinder leakage test should be carried out.(this is different to a compression test).Good Luck

Code p0507 on a 2008 trailblazer


Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL illuminates. this code sets when the rpm is 200 rpms higher than expected. below are some of the things that will have to be checked out.
A P0507 DTC trouble code may be caused by one or more of the following:
  • A vacuum leak
  • Leaking air intake after the throttle body
  • EGR valve leaking vacuum
  • A faulty positive crankcase ventilation (PCV) valve
  • Damaged/failed/dirty throttle body
  • Failed EVAP system
  • Failed IAC (idle air controller) or faulty IAC circuit

What do computer codes P0068 & P0496 mean ?


P0068 MAP/MAF is Throttle Position Correlation.In this error code:--- From the error code P0068 you have its indicating a bad throttle body or throttle actuator controller.. The 2 tps sensors inside read each other and if they differ for a few seconds or milliseconds then you get a this error code with reduced power. In some cases the new connector and wiring to the throttle actuator is required and in some cases getting the throttle body cleaned helps.---------------
And code P0496 - "Evaporative Emission System High Purge Flow".------------In this error the purge valve needs to be replaced. The purge valve is mounted on the inlet manifold under the hood.Its on the top of the intake manifold, passenger side. Two hoses (one on each side) and a wire harness on the front of it. It has a red w/blue stripe and brown w/white stripe wire harness connected to it.Remove and replace this valve.-----------------This will help.Thanks.Helpmech.

The idle has an intermittant stumble


Your Idle Air Control (IAC) valve may be dirty with carbon, simple fix with throttle body cleaner through the IAC passageway through the throttle body. Make sure it's throttle body cleaner and not carburetor cleaner, the carb cleaner is to corrosive to the gaskets used on the throttle body.
If cleaning the IAC does not help, then it's a good chance that the IAC is to far gone and will need to be replaced.
Good luck and thank you for using fixya

Is there any grease zirks on the 2008 Saturn astra?


Probably not. All the vehicles are getting away from putting in fittings. Any time I replace a component I make sure the replacement has grease fittings.

Saturn 1999 sl Engine has a high idle speed. How do I find, replace, inspect IAC?


The Idle Air Control valve is located on the throttle body. If you follow the intake tube from your air filter all the way back to the intake manifold, where the intake tube connects to is the throttle body. Remove the intake tubing and you can see the throttle body.

There are two sensors on the throttle body and a vacuum line. You'll see two harnesses going to the throttle body, one is the IAC.

However, a quick diagnostic check can be done without touching the throttle body to confirm your problem. If the car has a normal idle when initially started but then rises to a higher idle and stays there BUT then if you were to shut the car off and restart it and it comes back to normal that is the Throttle Position Sensor (TPS). This is also located on the throttle body (the other sensor to the IAC). If it is the IAC it will be high and maybe fluctuate a bit.

Reduced power light came on


reduced power messge is not caused by oil pressure. i assume this a 3.0L v6. this engine has a electronic throttle body which is a electric motor that operates the throttle plate that takes the place of a throttle cable. in cold weather the pcv (positive crankcase venelation) system accumulates moisture that will form on the throttle plate, in cold weather the water freezes and causes throttle plate to stick. when the ecm detects any malfunction whithin the throttle control circuit it is put in to reduced power mode that limits throttle position. usually resets after ign. is cycled. there is a service bullitin to re-position pcv hose behind throttle plate to reduce moisture bulid-up on throttle plate. your saturn dealer can perform this service.
