Hello folks, many thanks for all these attempts and thinking time devoted to my problem. It is really a puzzling situation as most of the things have already passed the test, yet the car is not behaving. Rovergauge has an indicator of idle mode, it's just my car that doesn't get it lighted up...

Sorry to keep on this but....how would it? I only know how to use the gun for checking the timing but wouldn't know what to expect in case of timing scatter. My problem is that the mechanical advance is always active and it is not possible to disconnect it as one can do with vacuum advance...

Hi, if timing scatter is the "spontanous" random variation of timing (dizzy wear etc etc) I thought of that but wouldn't know how to check it. Timing obviously varies with idle oscillations, problem is whether it is the cause or the effect or oscillating idling. For sure ignition has something...

hello folks, I have performed the suggested checkups. In fact cooltide did have a point....there was a difference of 8 mm in the throttle valve diameter distance to the plenum bore measured as per the workshop manual (it should have been 0,5 mm). Fortunately I had a spare plenum from another...

Hi, I will certainly follow this suggestion. As I said the engine has just been rebuilt, and in principle everything has been cleaned, but you never know and as you said it's worth going through it rather than just keep guessing + trial&error. I must admit that despite having rebuilt the whole...

That's right, but ....how do I check that? It looks as if it is doing it, but I have no reference to compare with. Are there any stated sizes, angles, measures or the like on the workshop manual that one could refer to? Has the throttle to be square to the plenum inlet? or has it to be at an...

Hello Kev, many thanks for your input. I was originally thinking on the same line, i.e. some air leak somewhere along the places you listed. However, performing the base idle setting I noticed that by clamping the stepper to plenum pipe to avoid the stepper operated air bypass I could reduce...

Hi all, have been here for long but never posted a thread myself, this time I think I need your advice or I won't get out of this mud. engine: RRC 3.9 Efi 1990 engine rebuilt completely (starting from cyl liners all the way up, everything that could be and was worth changing was changed..)...

Hi Ianski, sorry I was missing your post, thinking the topic was over. As far as I know a ballast is a resistor not a condenser, apart from that I agree with the proposed scheme. But my circuit hasn't got a ballast, the way to tell it is measuring tension between coil +ve and ground with ign ON...

It all worked beautifully.... up and running again.... THe module is now displaced to the side of the engine bay, close to the coil, where it shouldn't suffer the same heat problems as before. Ianski, as far as I know, the ballast resistor is something they used to add to make sure the coil...

Iansky, simply fantastic...... I'll go and get it wired immediately.... Thanks Ciao Adriano

OK kev, many thanks for the suggestion. I already have my 3pin module and would like to use that one to start with, + have already messed up the cables. As I understand you have the 2pin model, could you kindly provide me with the following info: is the -ve from coil connected to the left or to...

Hi All, having the same problem as many others did with replacing an old 2-pin IA with a new 3-pin model, I run into the problem of wiring it correctly. I searched for previous threads and found a few, but for some reasons they all stopped with the suggestion of buying the adaptor link lead...

Hi All, I just subscribed to this nice forum, and, as many of you will know, this is due to initial need for info. However with time I will hopefully be able to give back what I get, having spent some 25 years trying to make the damn thing rtun smoothly ..... In fact, I was going to claim I am...
