Location of spark plugs to change myself

When I start my engine it runs 30 seconds then shuts off.I start it back up it is fine. Ocassionally need to give a little gas when starting to keep it running. It does this about every 6 start ups. I had a tune up which consist of spark plugs and spark plug wires 20000 miles ago ( 2 years ago). Had the Ignition Cylinder re-placed at the beginning of July, about 2 weeks after this problem started occurring. No dummy lights are on in the dash.

Hi. I drive a 98 Chevy Malibu V6 3.1 automatic and lately I've noticed the car will decelerate hard when I let off of the gas (and no I'm not pressing the brake). This will even happen as I am going downhill. Also, when letting off the gas to coast, (around 35-50mph) the car shakes. The steering wheel goes side to side (similar to a video game controller shake for a racing game). If I apply the brakes, the shaking stops and no, I'm not pulled to either side of the road. Supposidly, the brakes are ok and I just had the following items fixed: air filter element, fuel filter, spark plug wire set, spark plugs, PCV, battery terminals cleaned, and a new starter motor. The listed items are from a random problem that was a bigger issue. The car would not start, didn't matter with a hot or cold engine. So I'd bring it to the shop and 20x's in a row, it would start for the mechanics. Ghost in the machine! I've read that this problem was mainly attributed to an anti-theft ignition switch thing but; unlike others, the anti-theft light never went on. So far, the car is starting properly. However, I am now very concerned about this shaking and very rapid deceration (like 40 to 20 within one city block, coasting)Its wierd and I would really appreciate some help with a good deduction. Thank you!Oh, and I suppose that I should mention that the entire fuel system has been replaced within the last 2 years. (I think it was a flood car)Thanks again!

1998 malibu 2.4 liter. I changed spark plugs and drove it maybe 15miles, no problems. Then out of the blue it started skipping and now it I can hear a vaccum leak comeing from under the power steering pump but I can not find where it is comeing from. Anybody have any suggestions please thank you

You might want to check the intake manifold gasket

What's the easiest way to remove the spark plug right near the firewall?

Hi my malibu has been shaking a little when I come to a stop my dad is going to change spark plugs and the wites because he think this may fix this problem. But lately my car drives good but when goin up a big hill I notice it struggles and when I got home yesterday something smelt burnt but nothing was leaking I checked my oil and water it was good oil levels a lil high but idont know what the problem can be.
