2006 f150 fx4 with the 5.4 engine. I just replaced the spark plugs with OEM motorcraft plugs. all the plugs are tight, but i have a gas smell in my cab when i turn the heater on. anyone else have this problem. It happened right after i did my spark plugs, i double checked and they are all tight

I've seen alot of ppl on other forums having the same problem. Most of them say the smell went away on its own after a month or so. Some cases it was loose plugs, leaky injector or a leak in the fuel rail that could not be seen.

X2, I had the gas smell as well and it did go away in mine after a few days.

I had to retorque my plugs to 25 ft lbs because I got the smell a few months later. Solved my problem

had the smell after dealer changed my plugs as part of the scheduled maintenance. I believe they re-torqued the plugs and it went away.
