It's amazing what a tune up will do...

OMG... just driving my car after I gave it a tune up feels so much better. Replaced plugs, wires, rotor, distributor cap... and it did exactly what I'd hoped. My car used to buck alot when I tried pushing her. Now she doesn't buck at all... it was the one big complaint I had about my car, and now that is gone... I'm so unbelievably happy. To celebrate I went out cruising, trying not to break the speed limit too much... and I didn't even notice that I had pushed her up to almost 90 on the highway... opps. Anyways I did everything I could to try and make it buck and it didn't. Supposedly someone changed the plugs etc to ix the issue before but it hadn't worked. I pulled out the plugs and they were spaced at nearly .60 which I am told is way too far apart. Anyways, I have the Bosch Plats in there now spaced at about .33. It makes a world of difference. I'm very happy. Anyway, just wanted to inform you all... oh, all the parts were included in my Christmas presents (we opened them up today, tomorrow I'll open mine from my Dad [Image: smile.gif]) Merry Christmas everyone... mine sure is.

Ain't a tuneup nice!!. For future reference, if it starts giving you the same or similar problems down the road, loose the Bosch Plats.

I've heard the Plats could give it problems, but I've also heard the contrary too. The plugs that have been in it were copper... and the ones before it, and they all gave it problems. Of course I think the people putting them in had no idea what spacing was... so that was probably the biggest issue. We'll see if they give me any problems though... if they do I'll go out any get some good copper ones. But until then I'll keep them.

Hey,

I recently replaced mine with bosch plats...bucked at weird times like at 1800 rpms and then randomly after that throughout the range. I thought I had cracked the porcelain or messed up my wires...I mean, these are bosch platinum! these should work well!

Replaced em with .60 autolites...less than 3 dollars for all three. Runs beautifully now.

Horror story...back in the 70's porsche started putting in bosch platinum plugs...messed up the fine machinery that is the 911 whenever they did it. People found out the porsche racing team used the cheapo copper bosch plugs.

Bosch Plats were designed for european sports cars. They do work well in many newer american and japenese models, but tend to perform poorly in older models, causing a numerous amount of bad side effects. The ceramic or porcelin (dont know how to spell that) shaft tend to break very easy and crack after little use and high temps. Most mechanics tell ppl to vear away from them. The origanal motorcraft plugs is what i use in my TC and they perform perfectly.

Take out those Bosch Plat plugs and throw them in the trash. They just dont work in these motors. I speak from personal experience on this. They will give you trouble. The stock cheap Motorcraft plugs work much better, and a set of 4 cost as much as one Platinum plug.

ex-Parts guy to the rescue!

Ditch the Bosch plugs anyone if you have them!

A few years ago I saw a report on spark plugs about the differences between copper, platnum, double platnum and specialty plugs (+4s, V-groove etc.) and reliability.
Buy copper plugs(And in my opinion use the Motorcraft plugs in a Ford)! The reason for platnum plugs is for the lazy people who don't tune up regularly. If you are going to own your car for 4 yrs/60,000mi why should you care about the next guy...throw the platnums in because they will last longer. They don't give better fuel economy, or more horsepower or anything..they just don't age as quickly, basically.

And, as far as Bosch plugs are concerned, the have the highest rate of manufacture defects of all the major manufacturers (Bosch, Champion(makes Motorcraft), AC/delco, NGK & Nippon/Denso)
