1986 Volvo 240 GLE B230A running on very low rpm (idle), jumps like a kangaroo and stalls.

Hello,

I have a problem with my car (1986 Volvo 240 GLE B230A). When I start the engine the car is running very poor on idle, but some times it runs fairly good until I use to accelerator pedal, and then it starts to run poor. It will eventually stall because of that.

However, when I start driving, the car runs pretty good (but not perfect), until it suddenly stalls without any obvious reason. Sometimes it just loses all power, and when I push the clutch pedal, it feels like the engine runs on something like 60 rpm backwards or something, until it eventually stalls. I have replaced ignition module, coil, ignition wires and plugs, vacuum hoses, distributor rotor and cover/cap (the red thing with wires from the coil and sparkplugs).

I have also replaced the EGR valve and EGR tubes which solved parts of the problem. Before I did that, the car jumped like a kangaroo even when driving (both when accelerating and driving in constant speed), and wouldn't let me drive faster than 40-mph, or more correctly, I didn't want to crunch the engine, so I turn around and drove home in low speed.

If anyone have comments or good advise, please help me. I'm now suspicious to the impulse sender in the distributor. Does anyone share that suspicion, or could it be something much more serious?

Thanks in advance.

If you have a Hall effect sensor in the distributor, I would suspect the wiring is coming loose where it is soldered to the 3 pin socket at the bottom of the distributor, happened to me twice. I soldered up the joints and they've been fine.

Is the Hall effect sensor the same as the impulse sender? It sounds familiar with the 3 pin socket, with a wire from the distributor, to the ignition control module. I have been cleaning the joints, but not actually bent on them to make the contact better. I'll try that this weekend. But what if that doesn't solve the problem. Is there, by any chance, possible to replace the impulse sender without removing the distributor from the engine? I'm afraid I'm not brave enough to do so alone. The vacuum clock mounted on the side of the distributor, with some pins/bolts, and one of them is more or less unavailable for a screwdriver.

Anyway, I think I'm one the right path now. Or is threr other things that can cause the problems I described in the original post?

Any advice will be appreciated.
