Is it bad to drive far if the engine is pinging. Mine did it a little today and freaked me out. It went away after a minute or so. Just want to make sure if it dose it again Im not hurting anything.
yes it could . if it happen when your just cruzing it could be bad thing . at the very least you would cook the cat cuz exhaust temp's will rise .air fuel ratio is to lean . PUT A 180 STAT IN and check your plenum pan for oil leak . HOPE THIS IS HELPFULL .:SPIN:
i agree with dodgefan360 u dont need a colder plug tell u find the cause of the ping . cold plug cold weather short trip's = fouled plug'sI did a 180 degree stat and a new Hughs plenum.....but I still get the occasional pinging.....any other things for a fix? or is something really bad going on?
The stat would cause the engine to run at a colder temperature, thus the fuel burns more efficiently.If the truck is runing lean wouldnt puting in a 180 stat allow colder air, Thus causing the truck to become more lean by sucking a higher density of air? Or am I not understanding what the stat will do?
180 stat lower's cylinder temp's . pcm see lower temp in temp sensor and add's more fuel ping gone . i dont have the deathflash and i have done the crank sensor mod to advance base timing and still no ping . cold engine needs a hot plug , hot engine needs a cold plug , to keep carbon build up to a min. longer projected nose plug will advance timing slightly as a shorter tip will retard timing that why a champion truck plug 4071 has been reported to help with pinging .

The above mentioned re-learning is what neccessitates re-mapping the spark timing & fuel ranges (a PCM flash).180 stats simply fool the computer at the coolant temp sensor into believing the motor is cold, so the PCM increases the dwell time of the injectors and they squirt in a bit more fuel. If you are running a colder plug, you may not get the proper spark to the A/F mix and my end up with a bigger mess. If anything, I'd want to run a hotter plug to expose more of the electrode so that richer mix sees more of the spark. BTW... the PCM soon learns the new fuel ratio and tries to advance your timimg, theoreticly leaning your engine back out. However you can compensate by putting a CAI on with a bigger filter to suck in more air. The PCM will see a lean, cold air temp at the IAT sensor, and add more fuel if it is within the loop parameter.
BTW, I didnt discuss octane, but should The higher the octane # on the pump, the cooler the fuel burns...well DUH! Sometimes that will help spark knock by a bit slower burn, but may be waste in motors that don't need it.
Now I have a headache...
