There are a lot of things that could cause these symptoms. Foremost I think would be that you have a vacuum leak somewhere. SO check all the hoses, first and make sure that there aren't any laying about unplugged. Secondly, you might think about replacing them anyway due to the age of the van. Rubber hoses only stay rubbery for so long and this could be the cause of the leak. If you can rule out a vacuum leak then I would suggest retrieving the codes, if there are any, stored in the computer. http://www.allpar.com/fix/80s-codes.html If that doesn't point you in a specific direction, then you may want to take it to the shop and have them run their diagnostic on it, which is more detailed than the onboard diagnostic.
could be a vacuum leak
If it is missing it is probaly a coil pack
Have you changed the fuel filter?
recheck wires to plugs sounds like two are crossed
Follow the plug wires from the distributor.
If the plugs, plug wires, are good then suspect a vacuum leak somewhere.
There are seals under the valve cover that need replaced to repair oil on the spark plugs.
Pull the gauge cluster out and use a low volt solder iron, and re-solder the points where it plugs in to the cluster, just heat it until the solder starts to melt.
Hey ya i have a 1994 grand am and i was having this same problem. What i did what replace the spark plugs. After i did this i took the car and and when i floor it no longer stutters when accelerating.
if it idles rough too, check your plugs, if not, check your fuel filter.
If you haven't done a tune-up lately (plugs and wires), do it. Do not "gap" the plugs, it will ruin the platinum coating. Install them right from the box.
i just changed the plugs on my 1979 frod 400 ci truck, and i had a similar problem. new platinum plugs, idles good in park, but feels like its slugish in acceleration. right now im actually getiing info on gapping my spark plugs and it sounds like that's what your car needs too.
Gas engine, none. Diesel, one per cylinder.
check for leaks if none try a tune up plugs wires air filter ect
No the number and the style of electrical plugs are different. Plus the 1997 has an extra motor mount.No the number and the style of electrical plugs are different. Plus the 1997 has an extra motor mount.
Intake manifold air leak or you need to put some fuel injector cleaner in. Did you gap your plugs correctly?
check fuel pump
Might be time for a tune up, new plugs, fuel filter, pcv valve, cap and rotor and wires if aplicable.
They are located on the side of the engine block on each side of the engine.
to change the plugs, remove the air filter element - lean over engine to back and unscrew plugs and replace same with new ones
A person can replace the rear spark plugs very easily. Disconnect the battery, remove the cables/boots and the old spark plugs. Put in the new spark plugs, reconnect the cables and boots, and reconnect the battery.
The turn signal switch is quite easy to remove and replace. The turn signal switch simply plugs in and plugs out.
There pay not be any power under acceleration if o2 sensors are bad, or if certain plugs are blown. This can also be caused by a bad battery or starter.Ê
They are on the left, right, and rear of the block.
Check to make sure the wires are all tight and you have them in the correct firing sequence. Also make sure you put the correct plugs in.
