Driving issues....... please help!

[pingaloca25]

after doing the k-member and coil overs yesterday my motor was running terrible.

any thing under 2.5k rpms the car shakes like a mofo. also throttle response is super slow

only thing we had to move was a ground cable from that goes from the driver side motor mount to the chassis. i grounded it to 2 different spots and it still runs like dog shit



let me know if you guys have any idea what it could be.



thanks

check connections to your o2 sensors and maf sensor. engine movement can cause havoc.

also make sure your exhaust is properly connected.

scanner said its #6 cylinder misfire.

possible COP failure, but most likely its the COP boot. I change all of mine every year when I do my sparkplugs. They are known to go out.

the boots are about $6
