  • The old Spark Plug question...

    Okay, I have finally got fed up enough with the poor performance to battle the demons of changing the spark plugs in my 99 Firebird.

    I read all the reviews on different plugs from old posts, and I have decided I am probably best to go OEM with AC Delco since I have no mods on my engine. Here is the question. AC Delco makes different types of plugs. I know the standard type that came in my car. I have also seen a type called Rapid Fire plugs (which I am under the impression are platinum?), and also an Iridium type. I read so many contradictory posts on this topic, even the "experts" are starting to confuse me. Any advise would be great. In addition, the whole plug wire thing is confusing too. Advise there would help too.

    I'm very happy with my AC Delco Irdiums...although no performance improvement over the stock plugs.

        Speed Freak - Typically I would be more concerned, but this time I beleive I know what the problem is... ME! I am a lazy no good bum who has neglected his spark plugs for 103k miles. I know my car hates me for it, but it still goes when I say so, so I decided to just do it. It has been doing all that jazz that cars do when they need plugs. The misfires, the rough running.

        Hey, possibly you can help me with a different issue though. My car is hell to start, usually takes about 5 seconds and some encouragement from the gas to get it to crank once it gets warm. The fuel pump seems to work, but I have no way to test it, other than listen for it. It has been doing it as long as I have owned it and it is anoying. It always starts, but it would be nice not to have this issue.

          Change your fuel filter to help the starting problem.

                      Yeah, I have been thinking of replacing the cat anyway, i need new pipes so it just makes since to replace all of it. Bret - You said you replaced your injectors, how much? Mine have always tick and it annoys me.

                      Looking forward to hearing how the fpr replacement goes. I really am at a loss except maybe a fuel pump. The thing is I have had the car for nearly 2 years, and it has always done it. Always been a pain to start, unless it is cold, and always ran perfect until the plugs started to age.

                        Hard starting might still be plug-related. On my previous car I let the plugs go until about 80K miles, that was before I knew that plugs actually wore out. It got so bad I could barely start it in the morning. replace those plugs before you do anything else, since you KNOW they're bad.
