P1174 = intermittent rough idle. There are multiple possible causes for that, lets start with the most obvious ones: the sparkplugs - bad gap or defective; next is the ignition system - the spark is too weak because the ignition module is malfunctioning ; finally th injectors - dirty or malfunctioning.
To all of that you must check the fuel line pressure and the wiring to the injectors. A lot more testing is required and it must be done using specific testers.

How do the obd 2 clear the check engine light on a 1995 Saab


  • A 1995 Saab 900 still used the ISO 9141 not OBD II so an OBD II will serve no purpose to your vehicle. Saab 900 did not use OBD II until 1996. If you want the check engine light to go away on this vehicle you have to fix the problem and then the battery disconnected for a couple minutes and the light should stay away if all is OK.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

The check engine light is on my 1995 Saab 900s. I can not find a techician with the correct scanner.How can I turn off the light?


There are three ways to reset a check engine light.

1. Disconnect the battery, wait approximately 30 minutes, reconnect the battery. This resets the cars computer which also reset the check engine light. On newer OBD (on-board diagnostic) compliant vehicles this usually does not work. See step 2.

2. Reset using an OBD II reader. When you hook an OBD II code reader up to your vehicle, you can reset the computer using the code reader.

3. Fixing the problem. Generally the check engine light comes on for a reason. Usually it is emission related (sensors, gas cap) or electrical (faulty wiring). In this case the way to reset the check engine light is to fix the problem

My saaB 900s try to start But won't . I replaced every thing , Fuel pump, ignition coil, distriButor and ecu But car still wont' start. The engine light was on But after disconnecting the ecu and ICU, now...


If the fuel pump is'nt running then it's a bad relay or blown fuse. If the pump is running then it could be a few things, a bad timing belt, bad cam sensor, bad crankshaft sensor, could be the timing is off which you can adjust with the distributor, or it could be a bad o2 sensor or MAP sensor.

My saab 93 showed error code P0100. I renewed the mass flow sensor but the error code and the poor performance is still there. the revs are limited to approx 3500.


P0100 OBD-II Trouble Code

Technical Description

Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes

A code P0100 may mean one or more of the following:

* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.

Possible Solutions

Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:

* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.

What does p0140 code mean n what culd i do about it


O2 sensor. There are troubleshooting procedures here: http://www.obd-codes.com/p0140
Procedures require the use of a good OBD II scanner.
If you have the money, you can try replacing the sensor to see if it clears the code. It's easy to replace.

Obd II locations on 1995 saab 9000 cs


In 1995 they made different systems. If it has OBD, then it should be the conventional 16 pin connector, found underneath the drivers steering wheel area. If its the older type, then it has a 2 pin black connector under the center console area. Hope that helps
