The Control Unit Bosch Motronic

[andrealx]

Hello everyone,I open this new discussion sure your help;the car in question ? an Alfa 155 1994,that for some time of the defects,type strattonamenti,smoke, blue or black exhaust,difficulty? to keep the minimum and cos? via.From the time that, subjected to a diagnosis control unit in the memory has no errors, it might be the same ecu to be "crazy"?Requires replacing the eprom, or reprogramming,if the rewritable?
The most recent test done ? was to disconnect the battery to do a sort of reset and the car from a couple of days no problems,but ? really too soon to sing victory,thanks.

post a photo of the engine compartment.. I miss me I remember how it made 155.. ;)
butterfly in the intake and clean?

[ugoboss]

if ? the 94 should be an 8 valve, those were the fault of the coils, the respective forms of power with regards to tearing, for the smoke, blue or black can be either oil or gas in abundance, you must attack a good diagnosis, and then check all the data.

try to adjust the mass air flow sensor by turning the wheel of some of the shots to the right or to the left by removing the black cover

[andrealx]

I confirm the car ? an 8 valve,mass air flow sensor vane.For the smoke I thought, too, to of the crap in the intake,oil vapours particularly.I have to add that the plug wires have been replaced,unfortunately for? not with spare parts quality?,since recovering over the cables, the lid of the aluminium, which the car ? output and ? that went on for 20 years,
cables download by popping the car, and making it couldn't be handled.The lid is not pi? back in its place,that gives you no problems the same?

Have you done a compression test of the cylinders? That blue smoke I do not like, if it were a problem of power, I do not think that the smoke would be blue

Hi, diagnostic you used?
If, after reconnecting the battery the car is not from pi? no problem.
We can START WITH THE SOLUTION.

they are all ears :cool:

Good evening and happy easter!Small update,the 155 is not part of pi?!!Yes,I am two days who wants to know,the battery ? charge,the starter turns but the engine does not start.With regard to the type of diagnostics used,I don't say,because not ? was made in my presence;you held? informed....

[djang01]

Are sure that ? a problem of tightness of the bands. Try to remove a spark plug, put it to ground and see if it makes spark. But at least some sign when you try to put them on the bike?

[andrealx]

Then the car tomorrow or in the next few days will be? checked out by a mechanic,hopefully, competent, and passionate,that will solve,we still hope for more? that are not the bands!!

[danny677]

The bands do not greet you from time to time, to the maximum may be the rubber valve guide now cooked and overcooked.
The fact that no part or ? an electrical problem or the fuel pump that does not send ir? sufficient pressure to atomize the gas in the manifolds.

[andrealx]

After a long period of absence, here I am again to update you;the 155 ? been 15 days in the hand of an electrical repair shop that has performed the following works:replacing fuel pump,was a p? noisy and uphill the car was struggling a p?,as if there wasn't pressure enough;replacing the lambda probe,and a sensor, rpm and phase.I believe that the latter was responsible for the various shutdowns,sobs and smoke,lost the stage,twirling evil machine.
Doing the due touch wood the car is going well,we hope to continue!!

to tried changing the mass air flow sensor?

[gcmotor]

Check out all the points of mass of wiring. For the case there are water leaks in the passenger compartment ? if so, you must remove the ecu and open it because there could be water inside and then try to clean it.
