hi

for couple of days I`ve got this problem,
I start the car, it can start and run well or it can start with the crazy think I will describe later.

suddenly it goes crazy, just like a half of cylinders were not firing,
exhaust booms, engine shakes very strongly, rpm tach showa from 0 to high rpm, its undriveble in this condition, and suddenly it can go back to normal.
itssomething with ignition.
spark plugs are new, cables are new, cap` new, rotois ok, I`ve even got new module but thats not it....

today car was runing good, I was waiting for it to go crazy, it got warm, i`ve turn fan on, drive a 200 m and than i did go crazy...

I dont know what it could be??

what should I check?

vacum somewhere?

and the strange thing is it can run good or crazy just like he wants it to....

 

how hot is your motor running?? does this just happen when the motor is hot? sometimes if your motor gets too hot and you let the car idle, the fuel in the fuel line will start to vaporize in the line, so when you go to accellerate there is little to no gas left in the line past the fuel pump and it either wont have enough fuel to run smoothly (shaking), or none at all and just die. this has happened to me before
