Got a Major Misfire on my V8 Jeep
Discussion
Evening all,
Jeep Grand Cherokee 4.7 V8 on LPG 2002.
So last night, I pop out to the local takeaway for some errrr Salad.
Anyway just as I pull up in turns over to LPG, turn Jeep off and go and get my errrr Salad.
Come outside, fire up Jeep and it splutters a bit but fires on petrol and switches over to LPG instantly.
Now as I pull away spiritedly it splutters and its running really rough to the point where it can hardly keep going, I managed to get it home with constant stalling and I have fault codes 301/302/303 pending.
I know its misfire on 1 2 and 3,
Today I have changed plugs, checked coils and all ok although the plugs were sodden with fuel put it back together and still no different.
I just dont get it, literally one minute perfect the next like this.
Thoughts please,
