Hey guys, I just got my car tune and my aem wide band seems to be running to rich, it's jumps from 13.5 to 10.00 and sometimes lean, so I checked I took my spark plugs out and there seems to be gas sitting on top of my Pistons, does anybody know why is doing that? By the way the motor is a b18b on boost, injector size 750. Any ideas what it could be?

 

It's a tunning issue should be around 14.7 on idle 12.0 on full throttle
Probably with a coil on distributor messing up if no codes and fuel map is correct

 

It's a brand new distributor and yeah it just jumps around, and by the way it's tuned on a hondata s300. So is it bad having the gas there?

 

Check your timing and yes its bad it can damage the rings
Just because new doesn't mean it's good

 

Damn yeah I don't want that to happen and okay I'll check it as soon as I get home, by the way when I step on the pedal to 3k rpm the the check engine light lights up?

 

that should have been the very first thing you said. that right there will cause all of the issues you're finding.

check the code, fix whatever the code says.
done.

 

Okay I'll check that today and let y'all know what i find on the codes, but it only does it when I step on the gas, it'll hesitate a little to 2 step and then it starts 2 stepping but I'll check the codes and timing belt and see what I find.

Okay so I haven't checked the check engine light, but I did hear some loud scratching noise coming for the distributor, n when I put the key on, on not fully turn it on, the fuel pressure gauge goes to 40psi then shoots back down to 0, and Also you can hear like a loud hiss from the fuel rail? N I also bored bought a new distributor n still hear the loud scratching?
