99 dakota
99 dakota
I have a 99 dakota with the 5.2. I was wondering what maintenance i could do to it or what "tune up" i could do to the motor. It seems to get real poor gas mileage. When i say poor i mean 5-8 miles per gallon maybe 10. Just wondering on ideas i could do to tune her up.

What type of driving?
40PSI in tires if they are rated that high.
Check your air filter and oil.
Check your rear end gear lube.
Make sure your bakes are dragging.
Check plugs.
Make sure you're using good gas.
Get back to us with your mileage after you've done the above.

A question first:
1. Auto or manual?
When was your last tune-up? Plugs, wires, filters and the like are pretty cheap and if they haven't been replaced in a while, it might be time. That being said, I highly doubt those normal maintenance parts are the source of your problem.
You can clean the throttle body. Its not too hard to take off. Spray it down real good and get rid of all of the black deposits. Of course, I highly doubt this is going to solve the problem, but a little free maintenance never hurt anyone.
Now, are you having drive-ability issues? Bucking, stalling, hunting idle? Pings, ticks, or knocks? Is it doggy? Is it doggy throughout the entire RPM range or just at certain RPM ranges? How about oil pressure? Does it remain relatively constant or does it plummet when you come to a stop?
Finally, what is your oil consumption like? You pouring a quart in every 1,000 miles but are unable to figure out where it is going?
All that aside, I would bet a leaking belly pan gasket (or plenum gasket or intake gasket - all the same thing). Has this ever been repaired on the truck to your knowledge? If you need to fix this, you might consider replacing the MAP sensor at the same time. These two culprits will seriously hinder your engine's ability to efficiently use gas to produce power.

Automatic, 130k I bought it at 100k. There doesn't seem to be any power hold pack at all. There is a noise only sometimes of a tinging but it sounds more of something vibrating maybe not.. .and for oil it is burning about a quart every 1000
