This makes me a little nervous having to do the plugs and wires. But patience will be the hardest part. Last car I was working on I got so pissed off I put a baseball bat through the windshield.

How can i be sure that the mechanic fixes the front and the rear ones? Would it be possible they would only fix one or the other? How many total should they be replacing of the plugs?

the world needs more knowledge on these first gen lacrosses. and they also need more aftermarket support. kind of how the 3000gt/Stealth has their 3sx aftermarket support. id live to see a 3.8 fwd lacrosse hotrod. reminds me so much of the googley eyed luxury performance cars that Mercedes and Lincoln used to put out

How are the transmissions in these cars? I'm thinking about looking at a 06 114,000 miles
