hi i have a 1994 850 2.5 manual 20 valve keeps stopping with no warning then difficult to start have replaced rotor arm fuel filter but still no different no got to the point of where it hardly runs at all

you may be lucky after a while that it will fire up ok but after a few mins just cuts out completly no warning as though you have just turned the key off

there is a orange symbol that comes up with a green triangle and a pict ure that looks like the throttle pedal god only knows what this meens

its now driving me crazy as to what the fault may be even cleaned out throttle body etc the car has done 2160400miles but when ok is fine i do hope someone can give me some ideas must be someone here that can help hopefully

If I am understanding your post correctly I believe the light you are talking about is the Lambda light. It is the same as the Check Engine Light on US spec cars. It essentially means the car is mad about something.

The good news is that you can read codes that will narrow the problem down.

Instructions on reading the codes is here:

Read the codes from socket A-2 and post them back here. We can then give you advice on how to fix the problem or problems.

Welcome to the board. Take your time, use periods " . ", and make slow, clear sentences. There are a lot of knowledgable people on the board who can help you out.

hi in desperation called out diagnostic mechanic who said this prob was a faulty coil

1 coil and ign amp replaced still same prob
2crank sensor replaced still the same
3fuel pump relay replaced still same
4 rotor arm replaced
5 fuel filter changed
now getting to the realy silly stage justcant get it to run well maybe for 2mins then just cuts out dead no misfire before this happens
if you go back and check again you find no spark from coil yet again
i hope u may have an answer or anyone else that reads this may have
i am now beginning to think the prob maybe immobiliser or the ec u itself waiting in hope for some sort of info

Codes would be a huge help here but lacking that information double check, no triple check, the battery connections for signs of corrosion.

I am doubting the immobilizer since it kills the starter. From what I glean from your posts the car will still crank over.

Make sure that the wiring from the Crankshaft Position Sensor is routed well away from your coil wire to the distributor. In its natural state it wants to loop up right next to the coil wire which can cause interference to its signal. I doubt that is really your problem but it is a good one to eliminate.

The guy who "knew the problem" is throwing parts into it?
And it was not fixed on the first guess?

we can tell you esanctly haw to fizx the problemw asbut if we throw letterfs out there with out ...

Is this easier to read? Some clear sentences and punctuation? We empathize with you. Communication is especially difficult above a second-grade level when one is busy pulling their hair out over a poorly-running car.

I thought a person needed a scanner at the OBDII. Great news !!!

Hey Sperry,

How did you attain contributor status w/ only 24 posts. I've doubled your slack performance and only have a lousy 1 1/2 stars...What gives.
