NPK if i'm correct

 

Probably NTK, but, those should be good.

Might try running some combustion chamber cleaner thru it? (fuel additive)

 

​​​​​​I'll try to go get some tomorrow.
already ran a bottle of injection cleaner through it , as i thought at first it was an fuel injection problem.

The wierd thing is, it drives 1000x better on LPG ( liquefied petroleum gas ).

 

Are you running on gasoline now?

 

Yes all my issues are gasoline related. On LPG it seems to drive way better. Doesn't backfire at all..

 

What possessed you to go back to gas?? I would be real tempted to put the LPG stuff back.

 

​​​​​​
The LPG is still installed , and working. ( Well it did until my magnetic valve broke, repair on it's way )..


The issue is that i need to have correct readings CO% and o2 sens on both fuel types to be approved on the road. Especially gasoline needs to be right , as it's a gasoline car from the manufacturer..

 

Ah. Ok. That makes sense.

Have a read here about High CO readings.

 

I'll check my airfilter tomorrow
And maybe order new probes? Would you suggest to?!

I've added co cleaner additive to the fuel now , we'll see what that does..
​​​​​​
btw, if it would have cracked heads, wouldn't the car always run bad?
​​​​​​As it's sometimes working good and sometimes not, i can't imagine it's something mechanical..

 

My cracked heads only used a little oil and coolant. Truck ran great though.
