Re: need help fixing motor running lean
Had this same problem on my 88 1.5 DX. Turns out the timing belt was off a tooth. Kept throwing O2 sensor codes and pinging on acceleration. Got great gas mileage though!!

Re: need help fixing motor running lean
its pm6 or whatever everything pretty much stock on my d16a6 but header and CAI....and o2 is new. and I was wondering why my car seems to get so hot I check out the spark plugs and they all white as can be but ring is black so I take it runs rich at startup(warmup)...

Re: need help fixing motor running lean
I check timing 10 times and seems to be good but can it hurt if timing belt is too tight?
