LOL know what you mean. had the same prob with a peice of watermelon Corsica my wife had. (Man I hated that car)
Dontcha just love engineers.

Local Renaul mechanic said to my friend that engineers shouldn't design cars when they're drunk when that mech was fixing some engine support strut under friend's Laguna...

Just a side note here, my brother-in-law has a Mazda, think it's a 626, that was running rough until a couple of weeks ago when he changed the plugs for the first time, he bought the car new. He drives about about 70 miles to work each way and has for years. The spark plugs were worn almost to the nub, as well they should, they had over 200,000 miles on them.

Any good platnum plug will last over 100,000 miles in modern engines, if they're not something is wrong with your engine that no spark plug is gonna fix.

Nope, it wasn't a V-6. There were no plugs up on the front-end of the engine; all were in a straight row along the back of the engine almost under the firewall lip. Plus, they pointed down at an angle into each cylinder. Hence slant-6. If it had been a straight-6 all the plugs would've been along the top of the block.

I've heard that it is unleaded gas that we have to thank for the much longer lived spark plugs. When I first started driving in the '60's seems that plugs need to be replaced every 20,000 miles or so. Much more frequently than that in my two stroke bikes.

Not true. Better technology. A set of stock plugs will last 100,000 miles today. With today's computerized ignition changing to a "stock" set like we ran in the 60's and 70's will cause major performance loss.

Well that was one strange '90 Lumina if it had Mopars slanted straight-six mounted transversely at the front.

especially when Chrysler quit manufacturing that engine in eighties.

Oh well

I just rented a 2004 Ford Tauras 3.0L w Fuel Injection for a 600 mile trip. It is a fantastic piece of engineering, and great fun to drive, but it only got 20 MPG cross country.

My 1993 Ford F-150 with a 5.0L V8 gets 18 MPG on the Interstate.

None of this is really important but notice I'm still 'on tread'
