This sounds very much like an O2 sensor. Most likely the primary one. This O2 sensor controls the amount of fuel that gets into the engine based on how well it is consuming it. This is a pretty easy job on most cars and the part usually costs around $60. Since your service light is on, you can take your car to a local parts store and they are most likely able to scan it for you for free and that will tell you the problem for sure. I hope this helped!

2004 grand cherokee 4.0l one day it will run fine the next day it runs rough rich and when i step on the gas the engine cuts out and spits and sputters

When the "spits and sputters" happen are you in low rpm? Can you "by-pass" the sputtering by accelerating? Has your gas mileage suffered?

Buick lesabre 3.8 liter v6 gets poor gas mileage and cuts out like it is running out of gas if i accelarate hard or going up a grade

check the resistance of your fuel injectors.Should be 11.6 to 12.4 ohms, measured between the two prong, with the plug off. Look for one that is out of range low. When you load the engine, this one will **** up all of the electricity, as electricity takes the path of least resistance.

It's a "service reminder" based on your current mileage (odometer) Check your owners manual vs your odometer mileage and you'll see what's required for service.

I have a 1998 buick regal it has been recently tuned up was getting very good gas mileage and runnin well now it is burning more change in performance and no engine light codes

Good gas mileage on this car should be 19City 27Hwy. Gas mileage can be affected by many things. Assuming that the car has been recently tuned as you have indicated, I would: Check tire pressure first<-you'd be surprised what low tire pressure can do. Check for low oil level <-engine friction Cheap spark plugs. Let me know.

Missing hoses on engine to carburetor and engine idle speed is very high and gas mileage is very low.

You have lost a vacuum hose. Replace it and the idle speed will go down and the gas mileage will improve.

Poor gas mileage after a long trip on my 2008 Chevy HHR

How about Fuel filter? How many miles on vehicle? In some cases a fuel filter can cause this as well as a "lazy" o2 sensor. If to lazy, ecm will set check engine lite.

Better engine performance and gas mileage

try either a cold air intake or a chevron....a chevron is a cylinder with slots cut like arrow heads which will remove air turbulence....that alone will increase your performance at least 25% and horse power about another 40 to 50.
