Hi! Form all lest year I've problem with my engine,..I've written about it in some post in this group.
Week ago I've try to clean my Air Mass Meter,...and I've damaged it! This little plate has broken. I've bought a next, used AMM and installed in my car! So,..the car's started to work so good,..all my problems have gone away! The engine works so good, the acceleration is OK, the sound is good (under 3000 RPM, I can drive and talking witch passanger:) ) The car have the power and all have been so good. It's been only for 5 days,...and yeasterday and tommorow the problems came back again:(( The angine hasn't got enough power, the sound is loud (in 3000 RPM I hear engine clear in the cabin,..but for 4 last days,when engine works fine, I can't hear the engine when it's worked on 3000 RPM). So I've been so habby that my problem with engine has gone away and the engine after the year began to work perfectly.
I've thought that after the exchange AMM would be already all ok,..but problems back again.
I've think that it's connected witch no acceleration of ignition timing,...If I good know, in my system the acceleration of ignition is stering by the AMM. So this 5 days the ignition works so good,..but now it's not accelerate again,..why?
all the best....
Engine is B230F from 1988 year and in V740. The AMM is 0280212007 the ignition EZK117 and injection LH 2.2.
