Hey everyone.....today I finally got around changing the spark plugs on my 1998 Toyota Camry V6. One thing I can say about this experience is that.....its something I dont want to do again.....neither am I buying another 6 cylinder camry in my life.....unless the start mounting the engines differently. It took me about 20 minutes to change the front spark plugs.....I replaced the older Denso spark plugs with NGK Iridiums.....the Denso's looked gray in color at the electrodes....and the tips of the electrodes were black....I think thats bad right? Anyhow, I was able to change the front spark plugs with relative ease....but the rear spark plugs were just extremely hard to reach.....what I mean by this is that I stood near the passanger side for 2 hours trying to yank the damn rubber wire but it did not budge:cursin: ....I am soooo pissed right now because my hands are bleeding....my temper is out the damn roof.....One thing that did happen which was positive is that I took the car for a ride after changing the front spark plugs and I tried to feel the difference.....to do this....I got in my drive way....brought the car to a stop and just floored it....the tires screeched all the way through first.....this is something thing that has NEVER happend before....I know because I have tried....but now I want to know how much better it will perform if the rear three are changed.....I wish I knew someone who lives close to me that could help me out....I dont want to go to a mechaninc unless I have no other option.....Please tell me what should I do?????
