Miss fire ....
Okay so I had a miss fire in cylinder one two and three . I changed the plugs and only cylinder one came back so I changed the coil pack . It came back . I changed the exaust temp sensor because that was causing other Sensors to mess up such as circuit high and low in the maff and exaust temp sensor . So cylinder one was still messed up so I just changed the injector . Not the chec

Well if you checked and changed the spark components (spark plugs, coil pack) and you replaced an injector than what about the rest of the fuel system? i had a faulty fuel pump that gave me a misfire on 2 cylinders. Also, have you checked your fuel filter? From what you describe as "my motor runs like crap" than it could very well be the filter or pump. The squeeking problem could be a number of things.

I had the same sh**, it took me so long to know what's with it, I had three misfire 1,2, and 3, I couldn't know even my mechanic didn't know, so I took it to the dealer, and they said its the head casket, so when we took the engine out to replace the casket kit, my mechanic realized that it's the timing belt!!! It needed an adjustment! So you might wanna check that.
