Can I switch out engine parts from a Nissan Pathfinder to my car .
On the driver's side strut tower in the engine compartment is a heavy-duty black cable attached to a stud. This is the negative cable from the battery. Disconnect this cable to disconnect the battery. Note there is a plastic loop on this same cable end which can be slipped over the stud to keep the cable in place and prevent an inadvertent ground of the battery from the cable flopping around.
I put 2 ignition coils and 1 spark plug and my engine light turned off and it started running good . That lasted about 3 hours and then light turned back on and same symptomsNo progress. .well I don't have a diagnostic tester and I've never messed with cars before so I'm just you tubing it . I need help
