FROM my previous post...:

the tcs off light AND the slip light comes on from the time i start the car and the idle is a little weird..the car is stuttering/shaking..and when im driving i can hear noise i think coming from teh exhuast? it used to happen before a few times but it went away after a minute or two..today it stayed on for like half hour while i was driving and its annoying as hell. car is fine in the higher rpm ranges...but until 2,7000rpm its defly not the same..
almost feels like the catbacks not there..its some nasty stuttering noise.. maybe like bees in a can? i dunno
and the last time i started the car...nothing felt wrong with it..

UPDATE:
i drove down to autozone with the car feeling pretty normal and the guy pulled out a buncha codes..mostly tranmission solenoid problems because i swapped the tranny so i guess thats normal..

the things that weren't normal were two codes in particular:
P1320 - i heard that this is due to the ignition coil??
P0301 Cylinder 1 misfire

a third which is questionable... P0740 - circuit malfunction?

are the two problems interrelated? i need some detail as to what the codes mean..what would i need to buy to fix this problem? im tired of getting crappy gas mileage/random shaking of the car and rough idle. i already changed pcv valve recently, cleaned throttle body..

 

bump to the top ^^
