Engine stuttering, white smoke and gas smell from exhaust...
Can't get ahead lately, just one problem after another...
For background, I own a 2000 integra LS that some idiot decided to throw a stock B16A2 into, as far as I know nothing else under the hood was changed that would affect the engine.
Today, I started the car up fine, sounded fine, ran fine. As the engine warmed up, periodically the engine would start to stutter and the harder I hit the gas, the louder it got but I got very little power to the wheels. And it would just go away. After about 15 minutes, when I was almost to where I was going, it started and wouldn't stop. Now when I started the car not long after (Engine was still warm, but not quite operating temp) it started rough and continued stuttering in idle and when gas'ed. I also noticed white smoke coming from the exhaust only (that I could tell) and a strong gasoline odor.
After about an hour of research I have found A LOT of postings around the web pointing this to either a blown gasket or a cracked head, allow coolant to leak into the cylinders (causing the white smoke/steam), which may also cause the O2 sensor to go haywire and inject more fuel, causing the gasoline smell.
I did find somewhere, however, that this same issue could be caused by bad fuel injector(s), is this possible? How could I diagnose this?
Anything would be appreciated,
