2003 chevy trailblazer_lt_ext
After doing an oil change, I was revving it a little bit and noticed it sounded like it wanted to die before actually revving up. The air filter was changed about 400miles ago. When I changed the spark plugs, where the hex head and ceramic part of the plug meet where rusted and number 4 looked to have some slight oil? on it. We are at 111K on it now. After changing the plugs the rev seemed to be more responsive but didn't seem to have a "fast" rev like most engines (hit the pedal and it revs up). Is this just the computer doing it because its in park? It did seem to have better response when actually driving though. Oh and BTW, when you get on it, it downshifts and the RPM's spike to almost 5K freaks me out. Is this also normal? This is NOT my daily driver, it is the wife's. I drive a 98 stick Stratus with a 2.0l in it. lol Sorry if that should be another post.
