Robert, yes there are three box shaped items very close to each other on many GM V6 engines. They are the ignition coils. Each coil drives two spark plugs and they both spark at the same time. Yes this engine is a four cycle engine but for many years there has been a spark on the exhaust stroke to help burn any remaining vapors. I can also remember hearing about guys who could not understand how an engine was idling twice its ital speed and not sound any different. It turned out that some early shop equipment would monitor the spark impulse when determining engine RPM. This would give a false RPM read out.

Larry I took another look at the Grand Prix and what I found was what looks like 3 blocks with 2 wires coming out of each, the blocks are very tight together almost looking like one unit. The wires each go directly to there respective plugs. I can't tell unless I actually do it but It looks like if I take off the alternater I just might be able to snake my arm down in there and get at all of the plugs. If this turns out to be the case I will let you all know. I don't think I would find that little trick in a book. I might try this, if it works I will let you know. I have found that some times what works is the odd crap that people over look because it is not the normal way of doing things. I like to think out side the box so to speak.

M model back in the eighties which had one plug on the rear of a transverse engine that could only be reached from the bottom, and that after jacking the engine while the wheels were turned a certain way. I recall that G. M took a lot of ribbing, as it was quite clear that the engineers had failed to take in to account that spark plugs might need to be changed in the future, with the engine sill in the car. I had a Mazda 929 s, which had the plugs in wells which required the longest extensions I owned in order for my ratchet to work with the plug wrench. A blind man could certainly install those plugs as easily as a sighted person, as it had to be done by feel.
