Hey all,
I had the front 60K work done on my '94 MTX about two weeks ago while I was away on my honeymoon. Replaced timing belt, accessory belts, crank sensor, cam sensor and water pump. My mechanic noted that when he was lining up the timing marks on the cam sprockets, he noticed that the rear bank sprocket "tick mark" was out of alignment by one tooth (apparently done during a past timing belt change). Well, with everything freshened up (and properly aligned), I have to say there's quite a noticeable increase in power. I thought my SHO was relatively healthy before, but she's even stronger now. Prior to having this work done, I didn't notice a slight bog and hesitation when dipping deep into the throttle, but now there's nothing but instant, smooth and definitive acceleration. Even startups are smoother than before. And the best part is, I've been putting up with a pinging at moderate throttle under 3000 RPM since I bought the car over three years ago. I had changed the knock sensor when I did the upper 60K last year to no avail, and was getting ready to start trying the IAT and BAP sensors. Well, after the front 60K work, there is no longer any discernable pinging, which is great. The weather hasn't been particularly warm lately, so I can't say for sure that the pinging is gone for good (always seemed to be worse in warmer weather), but I'm pretty confident that things are vastly improved with this relatively simple maintenance.
Just thought I'd share my experience!
