When driving with my cruise control on 95 km (that's where it's most noticeable)it feels like the vehicle is ...uh jumpy? or ...it is getting fuel and letting off too much to feel smooth. Keep in mind it's not a huge amount of surge with increase and decrease of momentum. I feel it's wasting fuel and is annoying - I thot it was my imagination but, when relaxing a lot, I can feel my head lurch towards the back when driving on a flat and smooth paved hiway with very little wind.
The speedo reads a steady speed but there's gotta B a problem there because it feels normal at 115km - cud this B spark plugs?
This truck runs great when driving at all times without the cruise on so ..I guess it shudn't B plugs - cud it B a vacuum line or speed sensor maybe?
Where do I start looking for a remedy?
Anybody?
Thanx - Brian
