engine problems

so yesterday im driving home and my car is sounding weird, its sounds like the timing belt might be off but, idk, its sounds like it may be miss firing, and is giving off a weird smell,thought is was the coilpacks but today i put new ones in, but still having the same problem, need some help

I'm guessing that car is under warranty, better take it in before they say its void due to you trying to fix it yourself ;)

any codes gettin set off? also, what kind of mufflers did you use for your custom quad tip?

[ElCapitan464]

i bought the exhaust off my friend so idk, do u think that could be the problem?

[Obvis07]

lol no. the smell is coming from ur testpipe and if u have a CEL its from the testpipe. its purely engine lol. dont trip

Might want check out the spark plugs since you just replace the coil packs.
