Help, VWDOC! 96 xj pings at idel
Doc, or anyone else. I was all over the engine on my 96 XJ this weekend and
now it pings at idel untill warm. Sounds just like my tdi jetta. It
otherwise runs fine. I think I messed up a wire somewhere. Both my coolant
and air temperature senders are out of range but this just started so I
don't think they're to blame but I'll pick them up today. Anythoughts on how
to troubleshoot this?
Thanks

Double check the vac hose to the fuel rail and if you took any ignition wires
off or changed plugs, check for a broken plug or crossed wires.

Re: Help, VWDOC! 96 xj pings at idel
yeah what DougW says.
Make sure your vacuum hoses are good to the MAP sensor and you did not
damage wiring to the TPS nor 02 sensor.
Pinging could be caused by spark timing too advanced, bad gas, too lean a
mixture or low fuel pressure, bad plug causing a hot spot or maybe even a
vacuum leak to name a few possible causes.
BTW what did you do since you were all over the engine?

Well I dropped the transmission pan to replace the filter. That was
complicated by the long dipstick/filler tube. I disconnected two connections
by the filler tube that were tye wrapped to it. I've rechecked them. Also
replaced the thermostat, coolant and air temp sensors were both off in their
resistance so I've replaced them. I also changed the oil and filter and had
put in the recommended amount of "sea foam" about 2 hundred miles
previously. I used the recommended 10-30 oil. I also have removed one quart
and put in lucas oil fortifier. This is the first oil change for me on this
car with 140k on it and I believe the oil I drained out contained a large
amount of "fortifier". I also replaced the distributor a month ago for a
worn shaft and "think" I got it in correctly. I'm going to retard the timing
by one tooth and see if what happens. Anyway to tell if the timing is
correct? Oil pressure is above 1/2 on the guage, engine is quiet above 1k
rpms with no or little noise while driving. Only code is "33" then the 55,
ac fan clutch and the ac works fine. I've not checked fuel pressure yet. At
this point I can't tell if it's a ignition knock or a wear knock. It sounds
like my jetta tdi with real good fuel (quiet knock) that's why I'm leaning
towards a ignition knock.
