Hi guys, I have 91 CRX and the question I have is, When the car is at idle i have no white smoke out of the tail pipe but when i throttle the car here comes the smoke then when i let it idle again no smoke. i asked a friend and he said that the smoke smelled like gas? could the car be running rich? if so how do i fix it. i was wondering if anyone has this problem or know of this problem and what can i do to stop this. Thanks

White smoke usually means coolant has leaked into the oil. A sweet smell will usually indicate this. However, I have heard failing fuel injectors can cause this. Easiest thing to do is an oil change and check the oil for contents. It will either smell like fuel or have a brown tint to it and be kind of foamy and a sweet smell. Let us know!

Suggested Repair

Change the oil and inspect it for fuel odor or coolant contamination, such as a brown tint, foamy appearance, or sweet smell. White smoke is more consistent with coolant entering the engine than with a rich mixture; failing fuel injectors were also mentioned as a possible cause.

Conversation Summary

The owner of a 1991 CRX reports white tailpipe smoke only when the engine is throttled, not at idle, and was told it smelled like fuel. Experts note that fuel smoke is usually not white and ask whether the car is using coolant or oil. A later reply says the white smoke does not smell like gas. An expert explains that white smoke often indicates coolant mixed with oil, identifiable by a sweet smell, and that failing fuel injectors are another possibility. The recommended next step is an oil change and inspection of the oil for a fuel smell or a brown, foamy, sweet-smelling appearance.
