Will a belt tensioner off Chevy Malibu quad4cyc fit my 2002pontiac Grand Prix 3100

SOURCE: replace headlight bulb

Actually there are two little black tabs on top of each headlight housing and you simply have to pull them up to release the whole headlamp.

Then follow the rest of emissionwiz's solution.

I didnt have to remove my alternator, I just used a 15 mm wrench to remove the left-hand threaded bolt holding the tensioner on. hope this helps

That depends on when was the last time the car was serviced and how many miles its done since the last service.

If its a high milage car then having the valves set should clear up the misfire and the lifter tick.

A code “multiple misfire” may mean that one or more of the following has happened:

•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Faulty catalytic converter(s)
•Stuck/blocked EGR valve / passages
•Faulty camshaft position sensor
•Defective computer

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Well you don't have to remove the tensioner. If you look at it, you'll see a 3/8 square hole in the arm of the tensioner. Put a ratchet wrench, or breaker bar in the hole, and you can move the tensioner, it is only spring loaded. The diagram for how the belt laces in should be on the radiator core support. Lace it for the majority around, move the tensioner, and once you have the belt in line, release the tension on the tensioner arm.
