I have had the oil changed regularly, had the PCV changed recently and also had the fuel system cleaned but still my VX coughs when starting. Yesterday, for the first time, it coughed, acted like it was going to run, almost stalled, but then caught and ran like normal. The coughing has been going on for about two months. Immediately after the fuel system and PCV work, it ran better than ever, but barely a month later, it is doing worse. Any ideas?

Also, this link explains about how to tighten steering but the last post says it's a bad idea to do this. http://club.vmag.com/ubb/Forum39/HTML/002813.html I've noticed some rocking in the steering wheel - I can actually feel it hitting when going over mildly rough surfaces as the wheel catches - and this is also a fairly recent ocsurrence. Is it safe to tighten the steering a little bit?
