Hi, I've been reading the passed posts and found it very interesting, I've had my Blazer for over a year now, and want to tune it up. My little sissy truck ran fine up until I got the brite idea to drive from florida to virginia (some 1800 miles). Before I left I changed the oil, the battery, and the air filter. The plugs, rotor and cap had been replaced with in a the passed 6 month so i thought nothing of it. I left on a rainy morning, it rained most on the way up and back. I noticed about the South Caralina border and the Service engine soon light came on border the engine was running a little ruff, and the Catalytic converter sounded like it had hole in it, the brakes had no vaccum assist and were hard to push. the further north I went the worse it got it would stall at lights and idol fast and slow, but seemed fine on the highway. In virginia I changed the plugs cap rotor and PVC valve. No change, i raised the idol a little so it would run at stop lights. And headed back to Florida. Another damp trip, but the truck seemed to run better the further south I got. Any ideas of what may have caused this. It still seems tempermental but is running a little better. The truck is old with over 200,000 miles on it but up until now the only trouble i've had is a fuel pump and tires. Also i noticed alot of carbon (black powder around the mouth of the intake can this be cleaned out like a regular carb (spray gunk) and is there anything else I can changeout during a tune up? THanks

Replying to: spck68 (Jul 14, 2009 2:42 pm) You said this is a '97 model. You shouldn't be spraying carb cleaner into it as there are components that can be harmed. You might try taking the MAF out and cleaning it with an approved cleaner. The throttle body can be cleaned, but should be done with throttle body cleaner, not carb cleaner. |

I have a 2002 blazer that will not start. It will turn over but not start up. I am getting a fuel pressure of 45, i do not know what it should be at. I am thinking my fuel pump is bad. I replaced one about 3 years ago. Anyone have a suggestion?
