I check try to check all the plugs but the 2nd i couldnt get out.

any help i can get from you guys, i think its crossthreaded but its too tight?

but i got 180 on the other 3, is this too high for my ls with 100k miles?
or is it good and ready to bolton a turbo kit?
does it make a difference i forgot to take out the ecu fuse?

LMK. Thanks.

 

Well I don't know abotu your "cross threaded" cylindar, but make sure the engine is WARM, and you have the pedal or throttle ALL THE WAY open (pedal on the floor) while cranking the engine, and instead of ECU fuse I find it easier to simply remove the injector clips....

 

i CHECKED it already
yes it was warm, pedal to the metal, and cranked till it turn over and over and over.
no fuse was removed or unclip the injectors.

would like help with the corss threaded spark plug, if anybody had this problem let me know how u fix it?????
