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....

 

Might want to start with checking for trouble codes

 

Doesn't sound like a vacuum leak to me....

IF its ignition its est/esc

but you said you replaced the module so that narrows it down.


Check your fuel pressure, check your FPR, and check for codes. Besides those things I'd say its one of the above ignition components.

 

fuel pressure has nothing to do with it because it does so
on the gasoline and on the gas-lpg,

tommorow I`ll replace coil and distributor

I hope that`ill do it, but if not what could it be?

I doubt that knock sensor could do somthing like that.?

I have to do it fast cuz 8.06 is

It might be the distributor, I had the same exact problem and when I took the distributor apart, the shaft had separated where it attaches to the reluctor wheel.

 

problem solved

turned out that when I had bad ground and I wanted to strart the car, battery went dead, I`ve connected another batterry,
ad when I turn on the key, 2 pins in ecm fried, both - ground
ground went thru them,

and they were shortcirtuiting,

eariler i`ve chandeg cables,cap, distributor, coil, and nothing changed

then I checked there and there was it
finnaly

 

Could you elaborate onto how you tested the "fried pins"?
