Car is having two kinds of trouble.
Recently is started running rough missing sounds muffled etc. Mech said it was the injectors leaking and manifold problems anyway have anything like this. Is it just the injectors need to be replaced of more?

The check engine light has been on for awhile i just ignored it since i was told it was wire sending unti malfunction and 400 just to check the stuff. Then some guy told me it was something to do with the brakes wire since its also sending off the trac light too?

Any help solutions etc?
