Today while i was driving, approx. (50mph just cruising) and all of a sudden my car starts to sound like a wrx. The exhaust tone was very lopey and there was lots of hesitation. I pull over and it sounded like an injector was unplugged so i go to unplug the injectors 1 by one to see if engine idle lowers and the first one i pulled did nothing to the idle. I tried the rest one by one and they all made idle lower. I had the car towed to my house and i replaced the faulty injector with new one. i started up the car and the Idle is perfect again I can rev it and its all fine. Now the car blows tons of white smoke. At idle its not noticeable but when i push the throttle it smokes alot. The first thing i thought was blown headgasket. I checked oil, color is still fine, no milky effect. Doesnt look like i lost coolant after checking it. What would effects could that faulty injector have caused? thanks. Engine is a b20vtec just build, before this incodent, there was no smoke at all.

 

have you checked spark plugs to see wich is the causing cylinder/s?

 

also check your oil level make sure it is not over filled
