help- 325i 1990 intermitant stall

[charliebaked]

Hi struggling to find solution, had this beauty a couple of years and serviced myself, but strange fault occured and now is getting worse.
It seems worse on de- acceleration the rev counter drops virtually to zero and misses and if you arent quick with releasing the throttle you get a big misfire. So far i have chaned idle control valve, cap, rotor, crank sensor, cleaned maf, coil, fuel pump relay under bonnetfuel filter, fuel pressure regulator and still it keeps intermitantly doing this total loss of spark......i have read some forums that say it may be the ecu is there anyone who might help? cheers

If you have changed all the above things sounds pretty much the ECU is the only thing left !!!
