Kill it with fire

how do i post the scans?? (might be a newb question lol)
car also started reading a few misfires, going to do plugs and try to get ahold of a tuner
any ideas what else could be causing the knock, it rly came out of no where, car was running amazing
also did a TCC solenoid engine light went off but came back on reading same code
starting to think its the tune?

Could be false maybe? How are your motor and trans mounts? Uppers?

all mounts are looking good, checked everything over when the solenoid was done, ive ran 2 full tanks thru the car since it started, nothings changed, any suggestions, checkin all the plugs tomorrow

Umm any exhaust clamps coming loose?? The downpipe mainly. Fuel filter? It's not catted is it?

Yeah definitely check those plugs.

Start with plugs fo sho. Check injectors, fuel pressure....the list goes on really. Scans would help immensley

everything looks fine, rly starting to think its false

Check the secondary 02 to see if its smaking the tunnel...also start shaking things....see what's loose

only time the cars showing kr now is between shifts and even then its all over the place

been all thru this car cannot find anything, bad fuel pump? again the KR is completly eratic, seein it at all throttle positions, spikes right at the end of a gear then drops then spikes, has to be fake just cant figure out whats causing it!?! getting ahold of a buddy that tunes soon , doing ls6 springs this weekend to so going to double check everything again and replace both knock sensors, then go crazy lol

Test the pressue at the rail?

See if it is bleeding off by chance.

From what I hear turbo cars get pretty thirsty for ze fuel...so you might try a re-wire before going into a pump.
