Question
I saw the ansewr for the "service engine soon" on the GMC jimmy. I just bought a 1995 Chevy Blazer LS, with 89,000 miles. Two days later the "service engine soon" light came on. Is the ansewr the same? Just need to reset the light? It was serviced just before i bought it. It has the v6 engine and is four wheel drive with auto transmission. Seems to run ok.
                  Thanks,
                    Steve

Answer
Steve,

Sounds like the standard mileage warning.  After so many miles, usually somewhere between 60,000 and 90,000 miles many of the newer vehicles flash this warning to have you check the smog system.

If you have a manual for the Jimmy, check it, and see if they tell you how to reset the light.  Many times it is as simple as flipping a switch under the dash.  If not, you may have to take it to a shop that can reset the light with an electronic scanner.  If you don't have a manual, you can pick one up at most auto parts stores for around $20.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
