Nothing Below 3,000
 
Here is the situation my car has a misfire below 3,000 rpm
but only sometimes. It seems to kinda of phase in and out.
Anything above 3,000 rpm or so and it runs like a champ.

My car:
standard 99 civic ex 186,000 miles
y7 motor 60,000 miles
y8 intake manifold
y8 trans
safc
obdI conversion

Alright I have (before this post) changed the dizzy cap and rotor, plugs, injectors, plug wires, and o2 sensor. I have also checked the compression twice and I have 170, 175, 170,
165 starting from the dizzy going right. I have also checked the injectors to make sure they are functioning properly.

Warrick: I am running a po6 unchipped

I was playing with the car today, after I just installed my secound brand new set of plugs and wires, and the car seemed fine it idles normal. But then I go for a test drive and I found out that it only misfires under 2,000 with the car in gear. WTF!!!! Whenever the rpms get up over 2,000 it's fine.

timing belt skipped a tooth?

I have thought about that but wouldn't the compression be bad or low.

A new update just got back from test drive number two and the exact misfire only happens when I below 60% throttle. I will pull the plugs and see if I can tell anyhting from those.

Just went outside and checked my plugs. They are white like a mother fucker which means lean so should I just try retarding my timing or change my safc setting? Or maybe a little of both?
