Last night I started my car and all 6 misfired multiple times. I ended up with 14 codes and it all repeated 1-6 misfire and multiple misfire code. Any ideas???


I just did my sparkplugs sometime during fall of 2011 so I wouldn't think those would of gone bad already....


85k on the car 2008 tl type s

 

auto or manny tranny?

 

Manual

 

I see your problem as more a computer mgt problem...
What are the specific codes ...

 

300-306

 

any previous symptoms? should still be under warranty no?
those are all misfire codes; could be anything from fuel to ignition.. needs more diag.

 

I used to get o2 sensor codes 174 which is bank too lean. But that was fixed under warranty. And I don't think it can be covered by warranty I didn't get an extended warranty. I got the car new

 

its an 08; i would go ask and try your luck especially if you bought it new? go to the same dealer

 

If you've driven that much you should have gotten the extended warranty. If you never use it, it comes back in a check to you refunded. but we're Monday morning quarterbacking on that subject. It could be bad gas or coilpacks too. Who knows until you go for a cool check-up.

 

Well I cleared the codes last night after I checked them..... I think ill disconnect ny battery today reset the ecu and see if they come back if they do, well I have a serious problem. I was just trying to see I'd it happened to anyone before and they figured out the problem. I know the dealer will just reset it to begin with and tell me come back if it happens again.... I will put a fresh tank of gas tonight most likely ill try to go to a shell instead of bp and see what happens.

 

But I greatly appreciate the input from everyone

 

are you the original owner of the car?

you said it was a six speed. could some one have over-revved the engine!?
pull the heads and see!

 

Agreed, misshift, bent valves.
