how to change spark plugs in a 98 olds achieva?

Question

stalls and misses constantly

Answer 1

pull the plug wires one at a time,,and do the plugs one at a time so you don't cross them up,,and be sure and not over tighten the new plugs too much,and gap them good they don't come pre-set like some people think they do you,ll need a good spark plug socket so it don't break the new plugs when your putting them in,,they will break real easy good luck with it,i hope this help,s.

Answer 2

Is it a V-6, or 4 cyl.? Is rather simple on either. The V-6 is kind of annoying, as for the back three are a pain to get to. Just buy the plugs you need, with help of the parts store clerk, and I would recommend platinums, unless your getting rid of it. I'd also change the wires too, as they'd be quite old and brittle. I hope this is good enough. An easy way to do it, is also, do 1 at time. You'll see if you take all the wires out at once. So, don't do that.

Answer 3

What 3 hundred and sixty 5 days is it? no matter if it truly is a better moderen one, you'll likely ought to eliminate a canopy from the right of your motor. the canopy is supposedly a shelter, serves no objective in my opinion. On my truck, I truly ought to eliminate the gas rail contained in the lower back because it truly is a v6 to get to the perfect 3. no matter if it truly is older, all you want is a spark plug socket, a lengthy connector and the Ratchet. once you position in them although, merely hand tight. too a lot can strip out the threads contained in the motor.

Answer 4

Answer 5

You may be "barking up the wrong tree".

You may want to narrow down the problem before you start replacing various parts.

Just my opinion.......
