Squealing noise after spark plug change
This past Saturday I changed my spark plugs for the first time. I followed all instructions as far as hand tightening the plug first then following up with a quarter turn with the ratchet. I was careful as far as I know returning all boots back to their correct fitting. I did not remove the fuel rail. The squeal increases as the RPM's increase, and doesn't start until the car is completely warmed up.
I drove the car and noticed an immediate improvement however a squealing noise that I didnít have before is coming some near the heater core and I canít figure out what it is. It has given me any drivability issues or triggered any lights but the noise is driving me crazy. Any ideas?????
Year of the car: 02 GT
No New codes associated with the noise however I keep having a check gas cap light come on. This was happening before the spark
plug change though.
Spark plugs (NKG) were pre-gapped and double check at .54
