engine codes P0327, P0161

[etlsport]

not sure why you are throwing the code but from my understanding engine knock is premature detonation of a cylinder (go ahead and chuckle) its usually caused by bad/poor quality gas, the octane rating is an indicator of the knock resistance of the gas (89 is more likely to knock than 91) so i would start by clearing it and running some fuel system cleaner through your gas and see if that helps

alright ill try that... i always use premium, but in greeley (its a ghetto town) that doesnt always mean a lot...

ill run some STP injector and fuel cleaner

Any station can pump some crappy gas through their pumps, especially from the bottom of the tank (did you notice the pump running especially slowly?). You just never know...

The knock sensor is often mounted directly to the engine somewhere on the head (may be difficult to get to). It senses the premature detonation etlsport described and retards timing if it detects consistent knocking. I would see if you can find where it mounts and clean up the connection or replace it if you are highly motivated.

The second fault is the one to focus on for now - run the cleaners through your engine and some good fresh gas and see if the fault comes back.

Good luck!

sweet, thanks guys... im glad thats its nothing major, just a little crappy gas (which doesnt surprise me in greeley)

once again, the site saves me lots of money

im sure it would have costed me a couple of hundred dollars to have a shop tell me that i used bad gas

uh oh...

im throwing all type of check engine's again. i didnt get time to drop by autozone and have them read it for me. but just about every time i drive the VX im getting a check engine light again.

i talked to a friend of mine who is going to school for mechanics and he said that the knock sensor is a 1 wire sensor on the block...he quickly looked at my VX and guessed that its underneath the intake manifold on the front side.

im gonna swing by autozone today and have them give me the engine code, but im guessing its the knock sensor again. since last time i posted this i have been running octane booster in my tanks and its still not fixing it...so i dont think its just bad gas. so now i am going to delve in deeper because i dont want it to cause an issue in the long run.

is there a chance that a valve needs to be adjusted? (i only have 8k miles on my motor) wouldnt that be something that the shop that put it in would be responsible for??

just making me worried before i drive to moab and wheel all week, then head to lake havasu and wheel there, then back to colorado....

thanks guys
