Evap and crankshaft position sensor?
Hey guys just a question here kinda weird. I'm losing top end power and sounds like my engine is starving when I get up around 60mph. Any ideas would be helpful thanks a lot in advance
I would probably start with checking the simple things. Check for codes, check air filter, spark plugs etc. Maybe do a fuel pressure test. Loss of power under load at higher RPM can be any number of things, but stopped up air filter, restricted fuel filter or weak fuel pump are most common, maybe even worn spark plugs. On top of that a restricted exhaust or catalytic convertor could be the problem too.
Ok so I changed all the plugs (they didn't look bad). Did an oil change, air filter. Checked the codes and am getting a misfire 4,5,6 cylinders. Says possible crankshaft position sensor or camshaft position sensor. So I bought the crankshaft position sensor to try out first since its the cheaper of the two. Where is this thing located???
Keep in mind, (and I am only pretty sure about this for your application) Cylinders 4,5,6 all share one catalytic convertor, 1,2,3 share another. If a convertor is clogged and depending on which one, it will affect 4,5,6 or 1,2,3. A clogged convertor also usually causes a loss of power under load at higher rpm.
