My opti went out so i changed it w/ a brand new one a couple weeks ago, the car was running better than ever up until about last week sometime, now i can feel a stumble around 2k in the 4k range and up to redline when flooring it.

I noticed my heating wasnt working inside the car last night... Do u think this could be water pump related.. cuz i think i might have seen it leaking at one point which leads me to believe that it might have killed the new opti too.

someone please point me in the right direction cuz these car problems are just piling up...

stuff thats gone wrong in the past month:
opti- $260
exhaust falling off due to bad weld- $50 plus $50 for install
headlight motor cog- $45
$150 alarm went bad- another $150
heat stop working - ???

lots of other small ****..

 

1st thing i would check is to make sure the system is bled of any air pockets/bubbles. That could explain your loss of heat.
