I have a soft tonneau. It's impossible to tell what difference it does make. My 95 averages 25mpg. Best ever was 27.9mpg through PA 2 years ago.ib4200 wrote:How much of a difference does a tonneau cover make if any at all? anybody ever test it on a hardbody?
Have you installed new plugs, cap and rotor? Are your vacuum lines all good?sr20hardbody96 wrote:ive been having problems with my 96 hardbody xe model 4banger n im not getting s*** for mileage my engine light only comes on when the trucks running at first it said bad o2s and bad egr valve but i changed both n it stil acts the same n sumtimes it doesnt even turn over n i already tried injector cleaner didnt make a difference also when it cranks up after not turning over the engine light comes on and the truck starts idling really bad any help would be appreciated i already had a proffessional mechanic look at it should i take it to the dealer
I wonder if your EGR/PCV system is gunked up. This includes the: Breather, PCV valve and tubing, EGR valve and tubing, and the intake tract. My theory is that: At cruising speeds you have a vacuum charge in the intake system. If the EGR/PCV systems are not working efficiently, then there won't be as many inert gasses (practically burned of oxygen) taking up space in the combustion chamber, so instead of pulling inert gasses, it is pulling more fresh air (21% oxygen) than it needs to, and thus has to burn more gasoline to avoid going lean. The oxygen sensor can compensate for some of this, but it can't clean dirty parts.bareboatin wrote:I would be happy with ANY mileage that others get on this same vehicle. Thanks for all the output .
most vehicles back in the day didn't have the advanced electronics that today's vehicles have. personally I'd rather have an OBD2 vehicle than an OBD1 (OBD2 is where you can read the actual code with a scanner and was introduced as standard in 96, OBD1 just gives you the flashes). It's just so much easier to isolate a problem.Reverend D21 wrote:Not having OBD on these older trucks is what makes them so great, no emission test here in NY. Back in the day mechanics didn't need a little check engine light to help them fix a vehicle.
