2005 sable 86K. Running rough, mis fire code, lost power. Ran a bottle of Heet, cleaned intake, changed fuel filter. ran a little better but still bad. Plugs / wires / coil pack chaned 8 months ago. How can I tell if its a fuel pump, clogged injector, or timing belt?

When I say I lost power I mean acceleration has decreased. Electicle power is fine.

Start by checking the fuel pressure with a fuel pressure tester designed for your fuel system and comeback with the readings -we start here

No problem I will work on that over the next couple days. I will say though.... there was plenty of pressure in the fuel line when I changed the filter... because it sprayed all over the driveway... Lesson learned.

Looks like when I changed the plugs and wires last summer, I routed the # 2 wire touching the EGR tube. Replaced burnt wire and now I am running on 6 cyl instead of 5. Lesson learned.
