i bought a 1995 gts noticed it had a slight miss at low rpms.header pipe #6 wasnt as hot at start up as the rest.checked and replaced plugs. wires. same problem.cruising at a constant speed the car humps.took the plug out of #6 and car runs the same.was told maybe an injector bad.replaced them also .no luck! removed the heads and #6 valves are wet and the same color

Was there spark?

Was the injector exciting (was there constant 12V and modulate ground to energize the injector)?

 

[panther007]

yes plenty of spark. injector was firing

How was the compression in that cylinder?

 

[panther007]

compression was balanced across all cylinders. why would the cylinder be wet? and the piston be clean? the others have a carbon look about them

 

[HISSIN50]

The injector might have been leaking. The gas (solvent) could clean the carbon off the piston while the car sat.
