changed the spark plugs. now i smell gas
 

i changed the sparks in my 07 expy about 2 weeks ago and i was changing the oil today so when i was starting the engine up. i smelled gas coming from the engine. goes away after about 10 seconds what could it be?

was it cold? could be a loose sparkplug. If i was you i would check it out.....

When changing the plugs , did you move the injectors in their seat ? Maybe an injector o ring is seeping . Just a thought .

Checked the spark plugs and #8 was loose. Tightened it and smell seems to have gone away
