It is a pain in the **** on the 3.5L. One trick I have found is not only do you have to take the hydrolic tensioner off, but it makes it easier if you also loosen the manual tensioner right by the hydrolic one. there are 2 holes in the pully. when you finally get the belt on when lined up correctly, turn the tensioner so the belt is really tight, you should be able to pull the pin on the hydrolic tensioner and put it back in. If the belt is too loose in front one of the cams will spin to one tooth off. have patience, these belts are a pain!!!!!!

SOURCE: Emission system codes
P0421 - Warm Up Catalyst Efficiency Below Threshold (Bank 1)
P0171 - Fuel System Too Lean - (Bank 1)
P0446 - Canister Close Valve Malfunction
P1191/P1193 - Limp Home Valve - Low RPM
Before replacing the catalytic converter (bank 1 next to the firewall, Bank 2 is near the radiator), you'll want to verify it is bad (most likely is it sinse you also have a 'lean' code for Bank 1 - probably clogged). This can also cause misfires and engine stumble (low RPM) that's probably where the 1191/1193 occurred. The final DTC, P0446 - Canister Close Valve Malfunction, could be the valve itself, or the wiring between it and the PCM. Check the connector & pins for any damage/corrosion.
Hope this helps

1.Fuel injectors, related wiring, sensors, computer issues
2. Running out of gas, or poor fuel quality
3. Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
4. Incorrect Fuel Pressure
5. EGR system concerns: leaking EGR valve or restricted ports
6.Base engine concerns: low compression, valve train problems and timing issues
7. Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues
You will have diagnose each element until you find root cause.
And it could be more than one element faulting out.
