Title: O2 sensor
Post by: bus_driver on July 26, 2006, 08:57:53 PM

I have to ask if I am on the right path....my kick is burning the spark plug tips white my fuel mileage has dropped(worsened) and now my truck idles a little higher...1000rpm and when I start up I have a but load of gas out the exhaust

I am thinking my O2 sensor is not working properly is there anything else ???

out of range coolant temp sensor will cause it to run really rich.

White plug is a lean mixture, that and the high idle would seem to indicate an air leak in the intake.

the part that confuses me is how is it pure burning gas out the back and then lean at the plugs.... does that not contradict each other or is that just becuz i have no CAT.....

i first thought of an air leak i think i will take like wd40 and pray around the throttle body and check for any change.....

thanks guys

I once started mine up without the master cylinder attached. It idled high, popped a bit and had white smoke coming out the exhaust. It definatley had an air leak, lol.

Pure gas coming out the back? like dripping?
or could this be water, sure it's not coolant?
that creates white smoke too, and would do
funny things to the plugs as well as drip out
the tail pipe.

what i mean is raw burning gas not drippping like burn your eyes type of burning and then the spark plugs are burnt white and there is a a new one if I drive gentle the truck idles high if I drive like normal .....beating the piss out of it all the time it idles perfectly fine.... oh well got the o2 sensor now so will replace that and check it all again....
