Hi, I have some problems with my EF’s engine (b15b7)… While engine is cold, everything is OK, but when it warms up to the working temperature, it’s starting to jerk (hmzz.. I don’t know word to express that error :D), it’s feel like the ignition disappears, but engine still works.. and the most interesting thing is that when I turning on the blower, it’s works normaly.. when turning off blower or lights, it’s goes wrong again (when lights turned off, but blower and window wipers ar on it’s also working ok).. Any suggestions?

P.S. On indle, rpms are jumping from 600 to about 1500rpms..

Sorry for my bad English, I hope that tou understood my problem
