Ping....ping.....ping!!!!!!!!!!!

OK.........Had an error code for my 1994 JGC V-8 5.2L with 170K miles. Bad O2 Sensor. Changed it and got the fault to go away. Now I notice that my engine PINGS when it comes under a load from starting out from a stand still or when I speed up on the road. I use 87 gas but have tried a higher octane 89 but it still PINGS.........Any suggestions? I am at a lose with this one.

when you are low on fuel (1/8 tank or lower) put some 93 octane in it about 1/4 tank and see if that helps.

I don't get any pinging when starting out but I do notice it when going up hill. When I used 93 octane it went away. so I decided 93 is a lil prcey for me so I went down to 89 Octane, I still get a lil pinging but nothing like before.

Did you pinging just start with new O2 Sensor?

WOW.....93 octane is very expensive. Tried the 89 octane and it seemed better but still pinged some. I did not have any pings until after I changed the O2 sensor. Maybe its time for a tuneup......Cap,plugs, etc.....I just hate the pings.......It sounds like you know what....The O2 sensor was a BOSCH Replacement. Oh.....When I run the A/C it even worse.......I also had a problem at the same time with shifting/sluggish so I changed the fuel filter which was very easy to do with the clips on it. Took only about 5-10 minutes......That solved the shift/sluggish problem big time........Now I have to get rid of the pings......I am not about 1/4 tank of 87 octane and I will fill up Thursday ( payday ) probably with a full tank of 93octane ( and cry when I pay the big bucks ).......And I will see if the problem goes away.


TO BE CONTINUED !!!!!!!!!! SAME BAT CHANNEL ......BLAMMMM.....POWWWWW....Sorry got carried away back in my childhood.......LOL

check the knock sensor too..

[dksob81]

No knock sensor in the 5.2L

[89ltd]

oh........ sorry, carry on.

[esfd455]

Well thanks for all the replys..........I finally ran a full tank of HIGH OCTANE and now the pinging is gone. I have filled back up with 87 Octane and still no pings............I guess I had gotten a tank of bad gas.......Thank God that is gone......Thanks again.

Maybe having a full tank of the good stuff will help it in the long run, I think maybe I will have to fill up with the goo dstuff, it's been awhile since I actually filled the tank in my jeep with gas prices being so high.
