Tune up I need to do a tune up on my 2000 Pontiac Montana van. What is the best way to get to the spark plugs to change them. Also my transmission seems to be slipping. Could this be because the filter and fluid needs changed.

Slipping tranny can be caused by that. Rule of fixing cars is if not sure start cheap. Replace the Filter and fluid. Also it wont hurt to put in Lucas Transmission Additive with the fluid change. Change plug 2 ways if it has motor mounts on top then disconnect them and pull the engine foward. or

No need to rotate engine as I was told that sometimes this causes damage to exhaust link which is flex. First two plugs can be reached by going along the same channel as exhaust pipe from header runs. Last plug remove right side tire and you can reach up by body to change it. This one is blind, but it's possible.

2002 Pontiac Montana stalls in stop-and-go traffic especially on a down hill grade. Have changed gas filter. Diagnostic didn't find anything unusual.


First off, when was last healthy tune up? Plugs, plug wires, ALL filters and a good fuel system cleaning? I'd start there, then have parts store like Autozone, Advance etc.. do an OBII fault scan. I'm suspecting of tune up doesn't help maybe an oxygen sensor or a MAF (Mass Air Flow meter) are strong possibilities. But tune it first, and get scan done before just throwing parts at it.

Van dies when i sit at idle...


If I were you I would look at the Mass Airflow Sensor. If you diconect it and the problem gets better it's a sign that it's out. when you disconect it it puts of in to a default mode. So I am leaning twards that.

Changing spark plugs in a 2000 Poitiac van.


There are a few ways to doing this, and it takes time and a few band aids. You can remove the alternator to give you some room to access the rear spark plug with an extension and swivel spark plug socket. You can also get to the plugs from under neath if you have a ramp and long arm, an extension and swivel spark plug socket will help. You may have to use a 2x4 to wedge the engine to give you some room if you have larger arms. The other way is to tilt the engine forward by disconnecting the two top engine mounts. First replace the 3 front plugs and wire one at a time so you don't cross them. After you have changed the front plugs have a friend help you. Make sure the parking brakes are on and disconnect the two top engine mounts, release the parking brakes and let the transmission in park. Push the van forward slowly to tilt the engine forward far enough to give you room with out pushing it to far in to the radiator. Put the parking brakes on again to keep the van from rolling back and place a block of wood behind and in front of the rear wheels. Don't want to lose an arm. Replace the rear plugs with extensions and a swivel spark plug socket. Note, your going to have to replace the spark plug wire since the rear ones are really hard to remove and pulling on then will destroy them, not worth the headache trying to save them. Use platinum plugs so you can get 100.000 miles before you have to change them again so use anti-seize on the plugs so you can remove them again. Good luck and hope this helps, I personally go from under the van.

remove the ignition coil pack ( 2 10mm bolts on front of it and 2 13 mm nuts on the back side) u will need a long extension and deep socket for the back ones , and unplug all electrical connectors and remove it from the vehicle and you should be able to reach the back plugs without a problem.

With out scanning for codes or data this sounds like its in need of a good tune up.(spark plug wires, spark plugs ;use only recommended ac delco platinum or iridium plugs, pcv valve, air filter,fuel filter and have the throttle body and intake cleaned.Be sure to have the trouble codes cleared afterward.Hope this helps!
