spark plugs, or "does something need to be fixed"

From : jmc

Q: got my truck back from the mechanic they did replace my sparks. i asked for one as a learning tool. heres what it looks like the outside electrode is a pretty even gray with just the slightest bit of yellow speckling on one side. the tip looks a tad narrower than the rest. the center electrode is grey the top isnt flat- its markedly angled down toward the outside electrode. the insulator is pretty much white/very very light brown speckled. along the top edge its a yellowy brown. theres barely any corrosion at all anywhere but both electrodes to my eyes look worn. the threads look a bit dark to my eyes as well. according to the web page that was posted here a while back and another one i googled up my engines running a bit warm. one site suggested something about vaccum leaks it was a bike site - and indeed my truck still throws a p0455 evaporative emission system leak detected. could these two issues be related truck runs fine but still seems to lack a bit of the the g-force acceleration it used to have. thanks for any responses. and tgif! jmc .

jmc wrote still throws a p0455 evaporative emission system leak detected. could these two issues be related i dont think so. the po455 relates to pressure in your gas tank. it pumps fumes back to the engine rather than released to the atmosphere. i had that issue about once a year on my 2001 ram. check all hoses leading away from the tank. first i had a split hose end. then it had a crack on the plastic hose manifold at the canister. i dont believe it would cause any performance issues but if your state tests like here in az they will fail it if an emissions related code is present. .

suddenly without warning rm v2.0 exclaimed 28-apr-07 1238 am - and indeed my truck still throws a p0455 evaporative emission system leak detected. could these two issues be related isnt this usually gas cap related yes but gas cap was replaced and light reset. was back on very quickly. jmc .
