Help needed

[Gareth2510]

Hello my 940 has a problem its a 1997 2.3 lpt. If i start it it dies give it some gas it will stay alive take my foot off the gas and the rpm drops to the point of stalling & engine light comes on. If it doesnt stall it will hover around 450-500 rpm. I have tried fitting a new coil, crank sensor, and ignition module still has the same problem. I have tried a different fpr rpm increases if i pull the hose. Has a new distributor & arm new fuel pump etc. I have cleaned the eart leads on the manifold resoldered points in radio suppression relay & fuel pump relay ( clicks when priming ) rsr clicks after a few mins of ignition being cut. Now one thing i do notice is the longer of the two injection resistors gets red hot cant even touch it hot. Any ideas as to what the problem could be would be a great help.

The longer of the two resistors is the one thats getting hot. Ones for injectors whats the other one for.

The long one is for dim-dip headlights, mine gets very hot also. I unplugged mine to disable the dim-dips, but I'm not suggesting anyone else do that - unsure of legality, etc.

I wonder if your idle air valve is working correctly.

I have a near new one on the car but it was only a cheapy one. Ok so resistor thing is ok getting hot not that then. I have tried another set of injectors same deal i squirted some carb cleaner with the car running around the injectors no change in rpm from that. Its a weird one.

You should have put this post up in the '700/900 Series General Section'. I would have hoped that it might have been transferred but clearly not.

I would suggest to gain a wider audience of expertise that you re-post your original question there.

I'd second the posting in the general section bit - some real diagnostic savants on there.

Does it only have the starting problems when cold or is it when warm as well.

I'd question the maf and the idle control valve (under the inlet manifold) - a good soaking with carb cleaner does them wonders.

{Btw is is Warminster, Wiltshire you hail from - small world if so, i grew up there and am there most weeks if you need to try swapping some bits to fault find}

Will re post it when i can. Hot cold it does it on both occasions. Yes in warminster wiltshire by the army camp. Think il just have it scaned its got to be something simple as if i drive it its ok its just keeping it going once the key is turned. Probably is a duff cheapo icv.
