I have an LS/VTEC b18b block w/ b16 head and a P30 ECU
Recently when im having fun w/ my car and reving higher, i will sometimes throw a trouble code. Its the first oxygen sensor. Would the P30 ECu be causing my engine to run a lil too lean and not putting enough fuel into it because it is meant for a 1.6 liter engine?

 

What code?

 

check the o2 with a ohnm meter, ive ran a couple of friend b16 motors with a p30 and they ran fine. b16/b18 should be no problem.

What's so hard about posting the code number? Here, i'll help. Is it 1, 41 or 43? Knowing this will greatly narrow down the troubleshooting.

 

Its Number 1

I didn't realize there were a lot more codes than 1-23
I think i woulda gotten 45, Fuel system too rich or lean, if i was correct
thanx
