Stumped!

Hey Everyone~ I ve got a 2004 SR5 that started acting up last week. Started with a lack in power while driving. Plugged it up to a computer and it said misfire on cylinder 2. I changed all the plugs, wires, even ignition coils. Now it is firing, but flooding and not engaging. I m stumped. Could it be an 02 sensor? Bad head gasket? Any thoughts would be great. Thanks, fellas~

 

No codes?

How do you know it's flooding? On an EFI vehicle that's an indicator of a stuck open injector or a non firing plug(s)

What do you mean by 'not engaging'?

 

The flooding is a guess-- it smells like gas. And 'not engaging' meaning that it is turning over but not starting. I am a total mechanical dummy, to be perfectly honest. So I came to the experts-- Ya ll!

 

In that case I'd start by completely rechecking my work you mention here................

Because doing those things don't move it from misfire to no start w/o something being assembled wrong or something else disconnected along the way.

Remember I said

Since you smell gas, and have no start, I'd go with the non firing plugs.

 

That makes a lot of sense. Off to double check my work! Fingers crossed. Thanks again!

 

Did you connect the MAF sensor back up?

 

Occam's razor, fellas....I bought the wrong type of spark plug. (I'm an ass.) Problem solved!!

 

Glad to hear you got it running again. So, did the tune-up effort resolve your original misfire issue?

 

It did. Thanks again! She's purring.
